Research reveals dogs of the Americas

sled-viewInuit sled dogs and other Alaskan breeds are the only dogs with American origins, according to new research. Although the original canine stock has been traced to Asia, there is evidence of dogs in the Americas dating to 10,000 years ago, before transoceanic travel brought Europeans and their dogs to the continent. “Nobody knows exactly what happened,” researcher Peter Savolainen said. “Most probably migrated together with the humans that entered America from Asia via the Bering Strait. These humans became today’s Indians and Inuits.” The canines became Inuit sled dogs, the Greenland dog and the Eskimo dog, according to the research.

Alaskan breeds — such as Inuit sled dogs, the Eskimo dog and the Greenland dog — are the only canines with actual American roots, according to DNA analysis. All of these pooches hail from the 49th state and nearby areas, according to the study, published in the latest Proceedings of the Royal Society B.

“They are all equally American,” co-author Peter Savolainen told Discovery News. “They originate from the indigenous Indian-American and Inuit dog populations, and have only marginally been mixed with European dogs in modern time.”

Savolainen, an associate professor at KTH-Royal Institute of Technology in Sweden, explained the determination after tracing the origin of mitochondrial DNA lineages for several dog breeds suspected to be pre-Columbian, meaning before Europeans settled in the Americas. Dogs inherit their mitochondrial DNA from their mothers.

Alaska’s Denali National Park uses sled dogs to patrol its 6 million acres of Arctic terrain.Scientists widely agree that the original stock of all canines worldwide originated from Asia. This is similar to the widely agreed-upon view that all members of our species originated in Africa before some people left that continent.

“There was a single origin of the domestic dog somewhere in Eurasia,” Savolainen explained. “The exact place is still debated, but our previous studies strongly indicate the southern part of East Asia, basically southern China.”

The earliest archaeological evidence for dogs in the Americas dates to around 10,000 years ago, long before the dawn of transoceanic travel in the 15th century that saw the arrival of Columbus and other Europeans.

Most U.S. dogs today, however, have European origins. Golden retrievers, poodles and many more breeds fall into this category.

Inuit sled dogs, the Eskimo dog and the Greenland dog, though, show no European heritage in their genes. Like Native Americans, they were in the United States and nearby areas long before Europeans arrived.

“Nobody knows exactly what happened,” Savolainen said. “Most probably migrated together with the humans that entered America from Asia via the Bering Strait. These humans became today’s Indians and Inuits.”

“Our data shows dogs came in several migrations, at least one with the Indian-American ancestors and at least one with the Inuit ancestors,” he continued.

The result for Alaskan Malamutes was ambiguous, but these dogs appear to come from slightly different stock originating in Siberia, Japan, China and Indonesia. The Alaskan husky and the American Eskimo dog have a known origin from Siberian spitzes and European dogs.

The dogs with the most pre-Columbian Mexican heritage, according to the study, are the Chihuahua and Xolo (Mexican hairless dog).

The researchers additionally determined that a group of free-ranging dogs based in South Carolina and Georgia — known as Carolina Dogs — likely have an ancient Asian origin.

Carolina Dogs might have once been associated with a Native American tribe, the canine’s relatives turning feral once their humans disappeared.

“The reason might be that the human population keeping these dogs was wiped out when Europeans came,” Savolainen said.

Prior research by Sarah Brown of UC Davis and colleagues is consistent with the latest findings about the Inuit sled dog, Eskimo dog and Greenland dog. Brown and her team found “ancient DNA evidence for genetic continuity in arctic dogs.”

Scientists hope to use such DNA studies and other research on dogs to learn more about past human migrations. From at least 10,000 years onward, wherever migrating humans went, dogs often came too.

Newly identified genetic defect in dogs similar to rare human illness

Researchers discovered a genetic ailment afflicting dogs that is similar to a rare defect in humans called centronuclear myopathy. It results in extreme muscle weakness that eventually leads to death before the age of 18 in humans, and research could lead to treatments for both dogs and humans. Roughly six in 100,000 human infants are born with the disorder, and researchers tapped an international network of veterinarians and identified five dogs with the same genetic defect and symptoms. Studies on two colonies of dogs have tested new treatments. “Thanks to genomic comparison, we are understanding finally that dogs and humans are sick in the same way and can be treated the same way,” said veterinarian and geneticist Laurent Tiret. “Dogs help us and we help them.” ScienceMag.org/Science Now blog (6/13)

A rare genetic disease may be going to the dogs. About six in 100,000 babies are born with centronuclear myopathy, which weakens skeletal muscles so severely that children have trouble eating and breathing and often die before age 18. Now, by discovering a very similar condition in canines, researchers have a means to diagnose the disease, unravel its molecular intricacies, and target new therapies.

The story began when Jocelyn Laporte, a geneticist at the Institute of Genetics and Molecular and Cellular Biology in Strasbourg, France, uncovered the genetic roots of an odd form of centronuclear myopathy that showed up in a Turkish family. Three children, two of them fraternal twins, were born normal. Then, at the age of 3-and-a-half, they grew progressively and rapidly ill. (Most forms of the illness do not come on so suddenly.) The twins died by the age of 9. Their younger brother recently reached the same age but is very ill. Investigators traced the problem to a mutation in a gene called BIN1, which makes a protein that helps shape the muscle so that it can respond to nerve signals that initiate muscle contraction.

To find out how mutations in this gene could lead to such dire consequences, other researchers tried to genetically engineer mice models. But deleting the BIN1 gene failed to recreate the disease in mice, so the researchers had to look elsewhere.

Enter the dogs.

Laporte’s team joined with geneticist and veterinarian Laurent Tiret, at the Alfort School of Veterinary Medicine in Paris, to tap a network of vets in the United States, United Kingdom, Canada, Australia, and France. The idea was to track down and analyze dogs that had spontaneously acquired a similar condition. Because of their longer lifespans and larger size, the canines could model how the disease progresses and might respond to new therapies. Using veterinary records and muscle biopsies, the researchers found five dogs with features that mimicked human symptoms. The animals first showed problems at the age of 6 months, collapsing after exercise due to muscle weakness, for example. Biopsies of their muscle tissue also appeared similar to those of afflicted children.

Gene sequencing confirmed that the animals bore an analogous DNA mutation to the one seen in humans, which removes a large chunk of the BIN1 gene, known as exon 11. The finding of dogs with a similar defect that developed similar symptoms was key to confirming that the BIN1 is, indeed, the culprit in the human disease, Laporte says.

The team then tackled the question of how the BIN1 mutation causes such devastation. Using genomics tools, studies in cells, and analyses of biopsies, the researchers showed that the problem hovers around the formation of balloonlike structures called T-tubules deep in the muscle fibers. They are part of a muscle structure called a triad that helps convert electrical stimuli from nerve cells into mechanical muscle motion. When the T-tubules gradually become faulty, due to mutation, the muscles cannot receive the electrical stimulus to properly contract, leading to devastating symptoms. First comes muscle pain during exercise and trouble with walking, then weakness in muscles that control eye movement, and eventually problems with breathing. Using the dogs, researchers correlated the destruction of the tubules to these kinds of symptoms, as they report this month in PLOS Genetics.

Going forward, dogs will continue to be critical to unraveling this disease, Tiret says. In addition to the Great Danes, researchers, including Laporte, have found Labrador retrievers that bear two other gene mutations that cause different forms of recessive centronuclear myopathy, one linked to chromosome 2 and the other to the X chromosome. The investigators have bred those animals into two colonies. They can be used to study the natural progression of the illnesses and also to test new treatments, such as gene therapy. In fact, those treatments are already showing promise in the dogs, improving leg strength and diaphragm function during breathing, paving the way for clinical trials in humans.

The canines get around a huge hurdle that mice, zebrafish, and other organisms present when researchers try to recapitulate human disease. Often, those smaller animals express the genetic abnormality very differently from humans, says clinical scientist and pediatric neurologist James Dowling at the University of Michigan, Ann Arbor, who studies the myopathies and their genetic causes in both children and zebrafish. “The fact that the dog model seems to really faithfully recapitulate the clinical disease is really very telling,” he says. “Something that intervenes there would have a very good chance of working in patients.”

“Thanks to genomic comparison, we are understanding finally that dogs and humans are sick in the same way and can be treated the same way,” Tiret says. “Dogs help us and we help them.”

Sibling rivalry: Even the royal dog isn’t immune

Kate and LupoWith the birth of Prince William and Duchess Kate’s baby expected next month, experts say the pair would be wise to prepare their cocker spaniel, Lupo, for the royal infant’s arrival. The ASPCA’s Victoria Wells recommends all expectant parents do the same. Wells offers several recommendations parents-to-be can implement before a baby arrives, but in the end, owners must follow their intuition and re-home a pet they truly believe to be unsafe around children. NBC News (6/25)

Preparing a “canine kid” for a baby’s arrival might seem a little silly to some people, but it’s serious business according to vets and animal behaviorists. Expectant parents who don’t help their dog adjust before the new bundle appears may run into trouble down the road, when their furry friend acts out and vies for adult attention.

And the most famous royal pup in the world is no exception.

Experts say Duchess Kate, due to have her first child mid-July, should take precautionary measures now to ensure that her little Cocker Spaniel, Lupo, who the couple adopted last winter, and has already made Tatler’s 50 most fascinating “people” list, is all primed for the newest member of the royal family.

Victoria Wells, senior manager of behavior and training at the ASPCA adoption center in New York City, says she sometimes sees pregnant moms bring dogs to shelters before there’s even been a problem because they’re so anxious about their pooch getting along with their newborn.

She firmly believes that parents can take pro-active steps before a baby comes home to ensure that their “fur kid” is ready for the big change— and to calm their own prenatal nerves about everyone coexisting. She advises the Duchess of Cambridge and all other expectant moms this summer: Make sure your four-legged friend knows some basic commands, like “stay’” and “leave it,” so Fido doesn’t jump on the baby and listens when called.

“Go to dog training classes or hire a trainer,” says Wells. She also suggests teaching dogs impulse control before there’s an infant in the house.

Marc Siebert, owner and medical director of The Heart of Chelsea Animal Practice in downtown Manhattan, has seen many couples in his more than 20 years of practice balance new baby and beloved pet— and he breaks it down in canine terms for new parents.

“Most dogs will accept a new baby as part of their ‘pack’ readily,” he explains. But sometimes the dog will “see the new baby more as prey,” which is when you have problems.

So how do you convince your “canine kid” that the baby is part of the pack, royal or otherwise? Let the dog get used to the nursery and the smell of an infant before you walk in that door with the car seat, Siebert says. Encouraging your puppy to explore the new room and smell those blankets and onesies really does help a dog get acquainted with a new baby before the official introduction.

For first time mom Aubrey Bartolo, 29, of Greenwich, Conn., ensuring a smooth transition between her 7-year-old Yorkie, Rufuth, and baby girl Bartolo, born two weeks ago, was a top priority.

“We had our doula bring a blanket and a little hat home each night from the hospital,” Bartolo said, “And she’d wrap [Rufuth] up in the clothes so he was used to her smell when we came home a few days later.”

Bartolo also says she’s been reserving special, one-on-one time in their bed, every night cuddling with her “first kid”— no babies allowed.

Victoria Wells tells parents they can even buy an infant doll and use baby products on it, as well as “rocking it” to sleep in a glider to prepare the dog for what life will be like with a “sibling.”

“The key to all of this is positive reinforcement,” says Wells. “Whenever you’re interacting with the baby or the doll, before the real baby arrives, try to make a positive association for the dog and give him treats.”

Which shouldn’t be a problem at the palace, as the pregnant princess regularly receives treats for her pup from her loyal fans.

In the final analysis, though, it’s crucial to trust your gut, no matter how hard it might be to admit that your baby and pet are incompatible.

Unfortunately, for Stephanie Klein, 37, a blogger and Jericho, New York, mom of 6-year-old twins Lucas and Abigail, obedience classes and behavior therapy didn’t do the trick for her toy fox terrier, Linus. The dog had nipped various people before the twins’ arrival. And despite all the professional help she sought and progress he was making, Klein ultimately made the heartbreaking decision that it was too risky to have the dog around her babies.

Linus now lives happily as an “only child” with Klein’s sister in Florida.

Treating allergic dogs

Dog AllergyVeterinarian Jeff Kahler explains that dogs often exhibit skin irritation in response to inhaled allergens, and owners must develop a plan with their veterinarian to get symptoms under control. Testing for most, but not all, allergens often aids in the development of a treatment plan, Dr. Kahler writes. Different therapies including desensitizing injections and anti-inflammatory medication, as well as additional testing for secondary infections, may be part of the plan, but without treatment, Dr. Kahler says, the allergies are likely to get worse.

Bogie licks and chews at his feet to the point that they are now red and swollen. Pauline says her dog has been treated with various antibiotics and corticosteroids, but as the dosage of cortisone pills decreases, the incessant licking increases. Pauline has been told Bogie has allergies, and I would have to agree.

Inhaled allergens in humans commonly cause eye irritation. In dogs, these types of allergies can cause itchy skin. So can contact allergies.

Allergies usually worsen with time as the response to them gets more and more intense, because the immune system is hyper-reacting to something in the environment. Over time, that response becomes more exaggerated.

The self-trauma stemming from the allergic response can exacerbate the inflammation and can lead to bacterial infections or a yeast infection.

Bogie needs to be tested for inhaled allergies specific to his geographic area – California’s Central Valley. This can be done through blood or skin testing. Unfortunately, it is not possible to test for every possible allergen, so a definitive diagnosis may still elude us even with the testing. This, however, is not common.

He needs cultures for bacteria and skin swabs for microscopic examination before a treatment plan can be formulated. Once the results are in from the cultures, treatment can start. I would also start anti-inflammatory treatment to try and bring Bogie some much-needed relief. The medications used for these therapies will be determined by his veterinarian.

When the allergy testing results are in, the next step is to determine if allergy injections are necessary. This therapy can usually be done at home and can have excellent results in desensitizing Bogie to whatever is causing the irritation. Not all patients respond well to desensitization, and these patients will likely have to be medicated when the symptoms warrant.

There are other possible allergic conditions that might be causing Bogie’s condition. He may need to have a diet assessment, for example, to determine if a diet allergy is suspected.

Obviously, cases like Bogie’s are complex and there is no single therapy. One thing is certain: Bogie is miserable and needs to visit his veterinarian for a treatment that results in relief.

Dogs’ attachment to owners mimics infant-caregiver bonding

Susannah and LaceyDogs and their owners may develop a “secure base effect,” a type of bond documented between human infants and their caregivers. Researchers at the University of Veterinary Medicine, Vienna, studied the reactions of dogs in the presence and absence of owners and strangers. MedicalDaily.com (6/23)

Just like humans, it’s important for animals to develop relationships with their own kind. However, when it comes to domesticated animals, relationships can go in a different direction. Researchers have found that pet owners oftentimes develop strong bonds with their pets similar to that of a parent and their infant child.

This bond is known as the “secure base effect.” It’s normally a bond found in infant children as they try to understand the world around them. Children often gravitate towards their caregiver, using them as a base for interacting with their environment. The effect influences their daily lives and can also affect their performance in cognitive testing.

According to a new study, dogs become attached to their caregivers in much the same way that a child using the secure base effect. Researchers at Vetmeduni’s Messerli Research Institute of the University of Veterinary Medicine, Vienna, performed two experiments on dogs’ behavior.

In the first experiment, they tested 20 dogs’ reactions during three different settings: having an absent owner, a silent owner with a blindfold on, and an encouraging owner. The dogs had to manipulate toys in order to get a treat inside. The researchers found that it was only the owner’s presence that affected how the dog reacted. If the owner wasn’t in the room, the dogs spent less time trying to retrieve the treat from inside the toys. They also tested for separation anxiety in two pre-experiment absence tests — they found that separation anxiety had no effect on the dogs’ performance in the experiments.

“In this case, dogs that experienced strong separation distress would have been expected to manipulate shorter than dogs that were not distressed by the owners absence,” the authors wrote. “However, since the dogs’ duration of manipulation was not negatively correlated with their individual separation-related behavior score, we showed that the owners absence did not affect the dogs differently.”

Because of this, they concluded that the only reason the dogs didn’t spend as much time with the toys was because the owner wasn’t there as a secure base.

Following up on this experiment, the researchers then tested whether the dogs would compete the tasks when their owner was replaced with a stranger. The dogs showed no interest in the strangers, and, furthermore, didn’t show much interest in the food when the stranger was there or not.

“The fact that the presence of an unfamiliar human did not significantly increase the duration of manipulation in the dogs compared to when they were alone with the experimenter provides evidence for a secure base effect in dogs that’s specific for the owner, and therefore, comparable to the one found in infant-caregiver relationships,” they wrote.

This study provides the first evidence comparing the similarities of the secure base effect between dog-owner and child-caregiver. In a 2003 study based on the Ainsworth “Strange Situation” Assessment, 38 dogs and their owners were put into an unfamiliar room and introduced to a stranger. The dogs were subjected to four periods of separation in which the owners would leave and then come back. The stranger also left during one period, leaving the dogs completely alone.

The researchers found evidence pointing to a secure base effect from the beginning, when the dogs were more inclined to play with the stranger while the owner was present. However, there was more evidence pointing to attachment, because the dogs would scratch, jump at the door, or stare at the door or the owner’s chair when they weren’t present. They were also much more enthusiastic, and greeted their owners for a longer duration after the separation, than they did for the strangers. Finally, when the dogs were left completely alone, they were more inclined to make contact with their owner’s clothing and sat closer to their chair, rather than the stranger’s.

Having this relationship could contribute to the reasons why the American Heart Association (AHA) said pets can reduce the risk of heart disease.

“Pet ownership is an important nonhuman form of social support and may provide cardioprotective benefits in patients with established cardiovascular disease,” a statement said.

The AHA said that studies have shown having a pet can increase physical activity, boost favorable lipid profiles, lower systemic blood pressure, improve autonomic tone, diminish sympathetic responses to stress, and improve survival after acute coronary syndrome.

Experts share tips for keeping pets cool in summer heat

EnglishBulldogSonnyPuppy9Weeks2Summer means taking extra care to keep pets from overheating, an especially dangerous situation for brachycephalic breeds including pugs, bulldogs and others with short snouts or flat faces, experts advise. Other tips: Don’t leave pets in parked cars, where temperatures quickly soar to life-threatening levels; make sure animals have plenty of shade and cool water when outdoors; and walk pets early or late in the day to avoid the heat of the full sun. U.S. News & World Report (6/19)

No one ever told Linda Pegram not to leave her dogs in the car.

On a mid-80s day in April, Pegram cracked the windows for her 7-year-old Cocker Spaniel and 5-year-old Cockapoo as she shopped at a Walmart in Chester, Va. About an hour later, a passerby called police, who arrived to find the dogs dead inside the vehicle. Pegram, who was charged with two felony counts of animal cruelty, told local media outlets that she’s devastated and didn’t intentionally kill her animals.

It’s a grim reminder that, as the weather gets warmer, we need to pay extra attention to our pets. And keeping them inside vehicles on hot days isn’t the only health risk. U.S. News turned to veterinary experts who shared advice on how to keep our four-legged friends safe and healthy this summer:

Be careful with high-risk dogs. Animals cool by panting, and those that can’t breathe particularly well have the highest risk for health problems during the summer. This includes brachycephalic dogs, or those that have a short snout or are flat-faced – like bulldogs and pugs. Pay special attention to seniors and overweight pets, too. If your pet ever breathes in and out in a noisy way, he may have some trouble with airflow, which in turn means he may have a harder time cooling off.

Don’t keep your pets in parked cars. Research from San Francisco State University suggests that in 10 minutes, the temperature inside a car rises by 19 degrees. Make it 20 minutes, and the temperature spikes by 29 degrees; 30 minutes and it goes up 34 degrees; and after an hour, the temperature soars by 43 degrees. Dogs and cats have a baseline body temperature of 100 to 102 degrees, and their organs begin to shut down at 106 degrees. “Very quickly, you can literally be threatening your animal’s life,” says Cathy Unruh, an animal welfare advocate based in Tampa Bay, Fla. She cautions that you should never put your pet inside a car that’s been parked outside in the blistering sun – the seats could be so hot that they burn your animal. Make sure the car is cooled down ahead of time.

Provide shade and water. Seems like a no-brainer, right? You’d be surprised, experts say. Always make sure your pets have ample shade and water when they’re outside. Kiddie pools and sprinklers are a smart idea, too, says Jessica Almeida, transfer director at the Humane Society of Utah. “A lot of the time, they’ll just go lie down in the kiddie pool and get their bellies wet,” she says. But never spray your dog down with a hose: Chances are, it’s been lying in the sun, and the water inside is scorching hot – enough so to seriously burn your pet.

[Read: Pet Health: Dangerous Foods for Dogs and Cats.]

Beware of heatstroke. It’s more common in dogs than cats and often arises when exercising in hot weather. Louise Murray, vice president of Bergh Memorial Animal Hospital in New York, suggests taking your dog out early in the morning or later in the evening, when the sun isn’t so high in the sky. Try to keep animals indoors between 10 a.m. and 4 p.m., which is typically the hottest part of the day. Symptoms of heatstroke include increased heart rate, excessive panting, increased salivation, a bright red tongue, red or pale gums, vomiting and diarrhea. “Just think – our pets are furrier than us, and they don’t process heat as well as we do,” Almeida says. “So if it’s too hot for you to be hanging outside, it’s probably too hot for your dog.”

Apply sunscreen. You’re not the only one who can get sunburned: Your pets can, too. Dogs are most likely to get sunburned on the bridge of their nose, in the groin area, on the tips of the ears and on their bellies, and animals with a thin coat are at particularly high risk. Invest in sunscreen that’s specifically designed for pets. Don’t share your own because some common ingredients, like zinc oxide, are toxic to animals, Murray says.

Friday, June 21 is Take Your Dog to Work day

Under DeskCompanies see benefits when furry friends visit the office
Friday marks the 15th annual celebration of Take Your Dog to Work Day. Although not all companies participate and employers are advised to ensure staff concerns such as allergies are addressed, studies show having pets in the workplace can reduce levels of the stress hormone cortisol and improve collaboration and trust, and employers say they think having an animal around helps customers and businesses connect. The Oregonian (Portland) (6/14)

June 21 is the 15th annual “Take Your Dog to Work Day,” created by Pet Sitters International to introduce employees to the benefits of dog ownership and promote adoptions from local shelters and rescue groups.

Companies that want to include other species can take part in “Take Your Pet to Work Week” June 17-21.

Even in pooch-friendly Portland, not every company allows pets in the workplace every day. Some find that allowing their employees to take their pets to the office during the annual “holiday” decreases stress, boosts morale and may even be good for business.

“Most people do like dogs, whether they have one or not,” says Lori Venneberg, human resources operations manager for Beaverton-based Digimarc Corporation. “It just improves mood, cuts the tension, and it doesn’t necessarily interfere with productivity. In fact, it kind of reduces stress level.”

Recent research backs her up. A 2012 Virginia Commonwealth University study found that having dogs at work reduced levels of cortisol, the hormone released in response to stress. Another study by researchers at Central Michigan University revealed that the presence of dogs established a sense of employee collaboration and trust.

Digimarc participated in Take Your Dog to Work Day for the first time last year. Venneberg, who worked previously in a dog-friendly office, had heard about the day and thought it would be fun to implement at her current company.

The management did some homework first by identifying potential issues, such as allergies or a fear of dogs, and determined that employees with those concerns could choose to work from home that day.

The participants signed a liability waiver and agreed to bring dogs that were flea-free and current on vaccinations.

All employees had the chance to interact with the dogs during an ice-cream social, and the dog owners received a “doggie bag” filled with paw towels and poop bags and treats.

 Buster participates in Take Your Dog to Work Day at Digimarc Corporation.Lori Venneberg

“We had no accidents, nobody got in fight, it all went off very smoothly and was a very big hit,” says Venneberg, who brought her own dog, Buster.

The day went so well last year that the company is offering it again this year.

At Honda’s Northwest Training Center in Northeast Portland, technical training coordinator Monte Wolverton looks forward to bringing his Yorkie, Teddy, again to work this year.

Last year on Take Your Dog to Work Day, Wolverton found that Teddy served as a conversation starter during a training session with students from dealerships around the Northwest.

Wolverton also found that the dog’s presence reminded him to take necessary breaks.

“Sometimes, you get so focused on your job, but the dog has to take a break outside once in awhile,” he points out, “so it’s kind of a good refocus.”

Even at a cat shelter, a dog’s presence can be welcome.

Cat Adoption Team in Sherwood doesn’t participate in Take Your Dog to Work Day, but executive director Karen Green does bring her newly adopted yellow Lab, Sunny, in from time to time, which helps remind her to take breaks and get some fresh air.

“We’re considering creating a pets-in-the-workplace policy,” she says.

She points out that dogs could actually benefit shelter staff by helping to socialize the cats with canines and determining which cats like dogs, providing helpful knowledge for potential adopters.

Before implementing such a policy, Green says, it’s important to ask staff for input and make sure all concerns are addressed. Not all pets are suitable for the workplace, and vice-versa.

Those companies that do allow pets, either on a part-time or permanent basis, say that having animals around benefits not only employees but also their business.

“I think it’s wise from a business aspect,” says Bethany Sutherland, a commercial account manager at Hecht & Hecht Insurance Agency Inc., where company president Evelyn Hecht brings her dog regularly.

“It provides common ground for a lot of our clients, because a lot of our clients are dog owners,” Sutherland points out. “It’s a nice ice-breaker, and it kind of humanizes us, because it shows that we’re people, and we have lives outside of what we do for a living.”

Hecht & Hecht will participate in the “holiday” for the first time this year, and Sutherland is excited about the chance to spend her work day with her 7-month-old golden retriever, Ruby.

Dogs aren’t the only animals that can connect with clients, however.

Every day is ‘take your pet to work day’ for Paul McGill and Baxter at PondCrafters and YardBirds in Southeast Portland. Paul McGill

Paul McGill, owner of PondCrafters & YardBirds in Southeast Portland, says his two shop cats are very popular with customers and help his store to stand out.

McGill initially adopted Baxter, a gray tabby, as an inexpensive alternative to exterminating the mice that were getting into his fish food. When Baxter got lonely, he adopted Stella, and the two felines became fast friends. Now, McGill can’t imagine working without them. Neither, it seems, can his customers.

McGill notes that his return clients typically ask about the cats, tell him what they need and then ask how he’s doing – in that order.

He recommends any retail business with the potential to be pet-friendly to consider cats.

“My customers absolutely love the fact that we have cats in the store,” he says.

Tips to make sure Take Your Dog to Work Day goes smoothly:

  • Keep your dog on a leash unless he’s confined in your office or cubicle.
  • Use a baby gate to make sure your dog doesn’t dash out of your office.
  • Designate “dog-free” zones, such as bathrooms or employee eating areas.
  • Have a back-up plan that allows you to take your dog home if he’s not comfortable with you at work.

 

Dogs that are appropriate to take to work should:

  • Enjoy meeting new people and visiting new places
  • Get along well with other dogs or pets
  • Walk well on a leash
  • Be able to negotiate stairs and elevators, if your office has them
  • Be comfortable “settling down” in a crate or on a mat
  • Greet people without jumping on them

Registry helps pet owners find clinical trials for cancer treatment

alaskan malamuteCancer is the foremost killer of older dogs and cats, but pets stricken with the disease are gaining new options from clinical trials for new treatments that hold promise for helping animals and people. A team of physicians and veterinarians has launched the National Veterinary Cancer Registry to help pet owners find trials that might offer their animals more time while helping advance science. Cats and dogs are often afflicted with many of the same types of cancers as people, including lymphoma, leukemia and bone cancer.

U.S. News & World Report/HealthDay News (6/14)

THURSDAY, June 13 (HealthDay News) — If you hear that a friend’s beloved family member has joined a clinical trial for cancer treatment, don’t assume the patient is human.

Cancer is the leading cause of death in older dogs and cats, and clinical trials offer hope that effective medications will be developed — for humans and their four-legged friends, cancer experts say.

The new National Veterinary Cancer Registry, launched last month by a national team of animal and human cancer doctors, will point pet owners toward clinical trials that might benefit their beloved companions and speed up the development of life-saving therapies for humans.

“We will be able to decrease the cost and beat the time involved in drug discovery,” said the registry’s founder, Dr. Theresa Fossum, a professor of surgery at Texas A&M University’s college of veterinary medicine.

Because many similar diseases affect people and their animals, veterinarians and physicians say a lot can be learned from studying how treatments work in cats and dogs.

The drug-assessment process could be accelerated by a simple fact: dogs age many times faster than humans, and their cancers progress more rapidly too. Also, many canine and feline cancers — including sarcoma; non-Hodgkin lymphoma; leukemia; mesothelioma; and bone, ovarian, kidney, uterine and oral cancers — are virtually the same cancers humans have.

Experts not involved with the registry said the concept of the database looks promising.

“These clinical trials would be more real-world than a lab experiment,” said Dr. Peter Rabinowitz, associate professor of medicine at Yale School of Medicine and head of the Yale Human Animal Medicine Project, which studies clinical connections between human and animal medicine.

Dogs often are an interesting model for better understanding environmentally induced cancers, Rabinowitz said. “Asbestos causes cancer in humans 35 years [after exposure], but if you’re a dog, you get it in four to five years, so we can see how the cancers develop more naturally,” he said.

Fossum said she has always been bothered by the slow and cumbersome way drugs are tested. “If it’s a cancer drug, they’re going to put a human tumor in a mouse … but it’s not very predictive of how drugs will work in people,” she said.

Then, after tests to see if the drugs might be toxic in humans, the drugs are evaluated in human clinical trials, which take more than a decade to conduct. “So the drugs that are coming out now were starting [to be evaluated] 12 years ago,” she said.

Testing the drugs in pets speeds up the process, allowing researchers to determine if a medication works before taking it to human clinical trials, Fossum said. With a pet owner’s informed consent, “we can try a new drug that seems promising a lot sooner,” she said.

The concept of a cancer database for dogs and cats could expand to include other diseases, such as diabetes. About 800,000 dogs have type 1 diabetes in the United States, Fossum said. Other conditions that a veterinary registry could serve include endocrine, neurological and cardiac issues.

About 6 million dogs and 6 million cats in the United States receive a cancer diagnosis each year, according to the Animal Cancer Foundation, in Norwalk, Conn. If your dog or cat is one of them, you can register your pet with the National Veterinary Cancer Registry.

The registry was created by a consortium of animal and human cancer doctors, including specialists from the Baylor Healthcare System in Texas, the Texas Veterinary Oncology Group and the CARE Foundation, a Florida-based animal rescue and wildlife education organization.

Because the registry is new, it may take some time before effective clinical trial matchmaking can occur between animals and drug developers, Fossum said.

 Just Ask the Expert: Are intact dogs less likely to get cancer?

Q. I’ve heard about studies linking neutered dogs with an increased cancer risk. Should I take this into consideration before performing routine spays and castrations?

 


Dr. Timothy M. Fan

A. The epidemiologic findings in a recent study provide indirect and foundational evidence for the participation of gonadal status in susceptibility to or protection from various categorical causes of death in companion dogs.1 Based on the retrospective analysis of a very large cohort of female and male dogs, which were either gonadally sterilized (neutered) or intact, the findings of the study indicate that gonadal sterilization not only significantly impacts when companion dogs might die, but also provides novel information pertaining to why individuals die.

 

The study’s specifics

Specifically, gonadal sterilization significantly increased life expectancy in both male and female dogs by 13.8% and 26.8%, respectively, in comparison to sexually intact individuals. Importantly, the study findings identified a substantial effect of gonadal sterilization on the cause of death, with sterilization of dogs being significantly protective for fatality associated with various categorical pathologic processes including infectious, traumatic, vascular, and degenerative disease processes.

In contrast, sterilized dogs were significantly more likely to experience fatality associated with select neoplastic and immune-mediated processes. The identified association between increased fatalities of sterilized dogs from either neoplastic or immune-mediated diseases has the potential to direct future hypothesis-driven experiments that specifically address the participatory roles of chronic gonadal hormone exposure on tumorigenesis and immune surveillance.

In the context of cancer, sterilized dogs had a significantly increased risk of death, independent of age, associated with transitional cell carcinoma, osteosarcoma, lymphoma, and mast cell tumors; however, the increased death risk from cancer was not preserved across all tumor histologies, as sterilization status did not significantly influence the incidence of mortality in dogs with other common cancers such as prostate carcinoma, squamous cell carcinoma, and melanoma.

More research needed

Based on these initial epidemiologic study observations, prospective investigations addressing the putative and mechanistic roles of chronic gonadal hormone exposure and specific cancer-related death risks are well-justified. However, at this point before additional hypothesis-driven experiments can be conducted, it would be premature and imprudent to recommend the avoidance of elective gonadal sterilization because of concerns of increased death risk from cancer in companion dogs. Future rigorous and definitive cause-and-effect scientific studies are required before changes in sterilization practices should be considered.
