Dogs’ new tricks demonstrate memory capability

DiorDogs have the ability to learn and remember actions demonstrated by humans and perform those tasks after being distracted, according to experiments performed by researchers at Eötvös Loránd University in Hungary. The findings indicate the presence of “declarative memory, which refers to memories which can be consciously recalled, such as facts or knowledge,” researchers wrote. MedicalDaily.com (7/16)

Dog psychology researchers long believed that dogs, cute and cuddly as they are, can’t remember events that happened in the past. A new study has brought doubt to these beliefs, as the researchers’ findings suggest dogs could imitate novel human actions based on what they’ve seen, and not practiced.

In a paper published in Psychological Bulletin, author William A. Roberts argues that the ability to “assign points in time to events arises from human development of a sense of time and its accompanying time-keeping technology.” He says that animals have no sense of time and are cognitively stuck in time, and therefore have no episodic memory. Episodic memory, together with semantic memory — the ability to understand meanings and concepts — allows beings to recall facts and knowledge, an ability known as declarative memory.

To see if dogs could display these types of memories, researchers from Eötvös Loránd Universitym, in Hungary, had the owners of eight adult dogs train these dogs in a “do as I do” method in which the owners made their dogs sit and watch as the owner performed novel tasks, including ringing a bell and walking around a bucket. Each dog watched the owner perform these tasks for 1.5 minutes. For some tasks, the dogs were allowed to copy the task (a two-action procedure), while for others they were only allowed to sit and watch.

Then, the dogs were taken behind a screen that hid the objects used in the tasks from their view. During this break, which lasted between 40 seconds and 10 minutes, they were distracted by playing or just doing whatever they wanted.

By doing this, the researchers were able to see if the dogs had an ability to encode and recall the tasks without ever practicing them themselves, and they did. When the dogs were brought back, whether it was the owner or a stranger — who acted as the control — that commanded “do it,” the dogs typically performed the task. Dogs could complete the two-action tasks after waiting as long as 10 minutes behind the screen. They were also able to copy the tasks that they were only able to watch, spending only one minute behind the screen for these.

“The ability to encode and recall an action after a delay implies that the dogs have a mental representation of the human demonstration,” the authors write. “In addition, the ability to imitate a novel action after a delay without previous practice suggests the presence of a specific type of long-term memory in dogs.”

“This would be so-called declarative memory, which refers to memories which can be consciously recalled, such as facts or knowledge,” the authors conclude.

Dog’s excessive licking may indicate GI trouble

Dog lickingResearch indicates dogs who lick surfaces excessively could have a gastrointestinal disorder, and treatment of the underlying problem is likely to resolve the behavior, writes veterinarian Lee Pickett. The many functions of purring in cats are also addressed in Dr. Pickett’s column. BerksPets.com (Reading, Pa.) (7/1)

Q.  Henry, my 3-year-old shep-collie mix, has been licking the couch, carpet and other surfaces lately. What’s behind his behavior change?

A. Ask your veterinarian to investigate Henry’s gastrointestinal tract. Recently published research suggests that stomach and intestinal problems can trigger excessive licking of surfaces (ELS).

Researchers evaluated 19 dogs exhibiting ELS and 10 healthy dogs through blood work, neurologic examinations, oral exams under anesthesia, abdominal ultrasounds, endoscopies and biopsies of stomach and intestines.

Fourteen of the 19 ELS dogs (74 percent) were diagnosed with specific gastrointestinal diseases, whereas only three of the 10 apparently healthy dogs (30 percent) were similarly affected.

After treatment of the gastrointestinal diseases, ELS stopped completely in nine of the dogs and was significantly reduced in one additional dog.

If your veterinarian doesn’t find a gastrointestinal disorder, Henry may be experiencing anxiety. Your vet can help address that too.

Texas A&M veterinary school adds hands-on experience in addressing cruelty, trauma, neglect

Houston SPCA LogoTexas A&M University’s College of Veterinary Medicine and Biomedical Sciences has teamed with the Houston SPCA to give fourth-year veterinary students a chance to work alongside experts in investigating and treating dogs, cats, horses and other animals that have been subject to neglect and abuse. “We will be graduating new generations of vets who will disseminate throughout Texas and beyond with a deep understanding of animal welfare and shelter medicine,” said dean and veterinarian Eleanor Green.

By Brooke Conrad brooke.conrad@theeagle.com

The Houston Society for The Prevention of Cruelty to Animals and the Texas A&M College of Veterinary Medicine and Biomedical Sciences announced Thursday a partnership that will offer veterinary students a deeper look into cases of cruelty, trauma and neglect in a wide array of animals.

The Houston SPCA, the largest animal protection agency in the Gulf Coast area, investigates more than 9,000 cases of animal abuse and neglect and advocates for more than 50,000 animals a year. Through the partnership with the flagship university, fourth-year veterinary students at Texas A&M will undergo a two-week program at the SPCA, working alongside experts in cruelty, trauma and neglect to dogs, cats, horses, donkeys, farm animals, exotic animals and native wildlife, it was announced at a news conference in Houston.

Though Texas A&M veterinary students already receive a world-class, hands-on education, Eleanor Green, the Carl B. King Dean of Veterinary Medicine and Biomedical Sciences, said students will experience an “intimate immersion in the handling of animal abuse cases” because of the partnership.

“We will be graduating new generations of vets who will disseminate throughout Texas and beyond with a deep understanding of animal welfare and shelter medicine,” Green said. “It’s truly a win-win for the students, Houston SPCA and society.”

Green said some students have been exposed to cruelty cases, but the partnership will allow students to work with law enforcement in investigating the cases — something they likely haven’t done before. They’ll also experience going to court to see how the cases play out.

The first group of students began their rotations on June 3. Joe Pluhar is in the midst of his rotation, an experience he called “unique, both in volume and variety.”

Pluhar, who said he hopes to become an equine veterinarian after graduation, was able to care for a horse this week that had been mistreated and was unable to walk.

“There’s no other type of education opportunity like this for vet students anywhere else in the country,” Pluhar said. “[By the end of the rotation] we will have done upwards of 30 surgeries. At other schools, some students do maybe two.”

During their rotation, students live near the SPCA in an apartment that is funded by the college and outside donations. The SPCA is working to add a housing units on to its existing facility, Green said.

Kenita Rogers, associate dean for professional programs at the college of veterinary medicine, sparked the partnership over a year ago after she was urged by a longtime Houston vet to contact the SPCA.

“The reason this is so special is because it’s the largest partnership of its time,” Rogers said. “Just the breadth of species that are involved here — they handle up to 1,000 cases every day. It’s not just dogs and cats. It’s pocket pets, horses, farm animals and native wildlife of 240 species every year. There’s an incredible breadth of knowledge there to share with our students.”

How do you know when it’s time to say goodbye?

CliffordIn an effort to assist other pet owners struggling with end-of-life issues regarding their animals, Tina Ferner developed a package of information designed provide guidance for decisions during a pet’s final days. Ferner consulted with veterinarian Alice Villalobos, a founding member of Veterinary Cancer Society who developed an end-of-life assessment for owners. “The scale offers some objectivity while remaining sensitive to the caregiver’s wishes,” Dr. Villalobos writes on her website. “It will relieve guilt feelings and engender the support of the veterinary team to actively help in the care and decision-making for end of life.” The Blade (Toledo, Ohio) (7/8)

She provided him with hospice care, including pain management, and she had a going-away party for him before she had her veterinarian euthanize him in her home.

“My main goal for him was to find the highest level of comfort for as long as possible, and when that was no longer possible, I wanted him to have a peaceful, painless passing,” Ms. Ferner said. “He was a good friend, and we shared a very strong bond. He deserved all of this.”

End-of-life decisions for pets are difficult to think about, but there are options. Pets suffering from a terminal illness or a combination of age-related illnesses can be euthanized at a veterinary clinic or at home. Their remains can be cremated, or their bodies can be returned to owners for home burial.

Owners who stay with their pets during the procedure can comfort the pet, but some find it too difficult and prefer that the vet does it without their presence.

Clifford was diagnosed with osteosarcoma at the end of December. He was 9 years old when he was euthanized on Feb. 11, barely six weeks after the diagnosis.

“I searched for resources to help us with end of life care and there was nothing I could find locally,” said the Holland resident.

She put together “Resources For End of Life Care,” a guide that she plans to offer to clients at Canine Karma, the Holland dog-training facility she co-owns. She hopes to find local veterinarians to offer the guide to clients.

Ms. Ferner held a party to celebrate Clifford’s life on Jan. 27. She invited those who knew him to “come for a short pat or stay for the whole time.”

His quality of life continued to decline, and on Feb. 10, Ms. Ferner and her husband, Michael Plewa, decided to end his suffering. On Feb. 11, her veterinarian, Dr. Sue Savage, came to her home and euthanized the “big red dog” who had converted her from a “cat person” to a “dog person.”

Dr. Savage gave Clifford a drug to relax him before administering the euthanasia drug. Ms. Ferner and Mr. Plewa comforted Clifford during the process, including singing to him.

“Being his guardian and advocate and protector, he needed me to find the strength to allow him a peaceful passing,” Ms. Ferner said.

During her work with terminally ill humans, Ms. Ferner developed the Integrative Medicine Program at Mercy Cancer Centers that provides massage, yoga, guided imagery, and relaxation techniques for cancer survivors and their families.

Canine Karma has hired a licensed social worker and plans to offer grief counseling, support groups, and consultations for pet owners facing end-of-life decisions.

“If we can do it for people, we can do it for dogs,” she said.

When researching options for easing Clifford’s suffering, Ms. Ferner consulted with Dr. Alice Villalobos, a veterinarian who practices in Hermosa Beach, Calif., by phone.

Dr. Villalobos is a pioneer in the field of cancer care for companion animals and a founding member of the Veterinary Cancer Society. She has developed a quality-of-life scale for cats and dogs to help owners decide when it is time to euthanize.

The word euthanasia comes from the Greek, with “eu” meaning easy or good plus “thanatos,” meaning death. Euthanasia is literally the “easy or good death.”

Its intention is to end suffering and to do so in a peaceful, kind, and loving manner, Ms. Ferner said.

“It becomes the final act of love,” she said.

A quality-of-life scale may help everyone, especially those who are in denial about their pet’s illness, to face difficult issues, writes Dr. Villalobos in an article on her web site, pawspice.com.

Caretakers can use the scale to ask themselves if they are able to provide enough help to maintain an ailing pet properly, she writes.

“If we can create or restore a satisfactory level for our ailing companion animals, then we are justified in preserving the life of the ill pet during its steady decline toward death,” Dr. Villalobos writes.

The scale is designed to provide an easy guideline for assessment of the pet so that family members can maintain a rewarding relationship and nurture the human-animal bond.

“The scale offers some objectivity while remaining sensitive to the caregiver’s wishes,” she said. “It will relieve guilt feelings and engender the support of the veterinary team to actively help in the care and decision-making for end of life.”

Things to consider on the scale include hurt, hunger, hydration, hygiene, happiness, mobility, and more good days than bad. Adequate pain control and breathing ability are of top concern. If the pet can’t breathe properly, nothing else matters, according to the scale.

When bad days outnumber the good, quality of life might be too compromised. When a healthy human-animal bond is no longer possible, the caregivers must be made aware that the end is near.

The decision for euthanasia needs to be made if the pet is suffering, Dr. Villalobos writes.The complete scale for both dogs and cats can be found at: https://tinyurl.com/qualityoflifescale.

Ms. Ferner said she hopes to pass on what she learned during Clifford’s end-of-life care and euthanasia.

“I hope all of this heartache and research can help others,” she said.

Proper pet care keeps us all healthy and happy

person walking with dogsHappy, healthy pets are key to human and animal health, according to this article. Veterinarian Joan Hendricks, dean of veterinary medicine at the University of Pennsylvania, explains how owners can ensure good health and well-being for their animals and themselves. It’s important to start by researching the species and breed of pet that best fits your family, Dr. Hendricks points out. Pets need proper training to prevent injuries to people, regular veterinary care and good nutrition, and it’s essential to properly handle animal waste to prevent disease, Dr. Hendricks explains. U.S. News & World Report (7/3)

Sudden outbreaks like swine or bird flu remind us all too well that humans are not immune to diseases animals carry. These particular illnesses are most likely to affect people who work with animals regularly, like in a farm setting, but being at risk to an animal’s health hazards can happen in your own home. Improper care for a pet can lead to diseases, and a misbehaved pet can be dangerous to families.

At the same time, being around animals has been shown to increase a person’s well-being. The American Heart Association released a study this year that showed people who own pets have improved cardiovascular health. Animals often are used to help children with special needs or in visits to hospitals. Their presence can abate loneliness, increase altruism and reduce anxiety.

With pet ownership at 62 percent among American households, according to the American Pet Products Association, it is important people understand their risks and benefits. Having a healthy pet requires first learning about the animal you want, then caring and providing for it accordingly, says Joan Hendricks, the Gilbert S. Kahn dean of veterinary medicine at the University of Pennsylvania. U.S. News turned to Hendricks for advice about pet and family dynamics.

Understand your pet’s natural tendencies. Before you adopt a pet, know what role you want it to have in your family. Do you want a pet for companionship or to guard the house? Do you expect that your pet will join you on your morning run? Do you have the finances to pay someone to take care of your pet while you work or while you’re on business trips?

“People should know enough about their animal when they get it and after they get it,” Hendricks says. “They also must be open to the idea that they may not know as much as they thought.” Even dog breeds vary in terms of what they need from people, Hendricks says. Some dogs are meant to work, some need intellectual stimulation and some need little exercise. Bulldogs, for instance, are happy to lie at home sleeping a lot and show affection when you return from work. Great Danes also don’t need to run around much.

“If a pet’s specific needs are not attended to then they will not be good pets,” Hendricks says. They can even get sick with gastrointestinal upsets and develop behavior disorders – which could lead to wrecking furniture – if a family is not the right match. There are cases when pets aren’t the right fit for the family, she says, which is why it’s important to become informed before you adopt.

When it comes to exotic animals, such as tarantulas or pythons, there isn’t as much information available for pet owners. “There’s always a health concern for veterinarians that anyone who has one of these animals doesn’t know how to take care of them,” she says.

Train your pet properly. Animal bites are the single biggest health risk to kids when it comes to pets, Hendricks says. Avoiding this danger returns to the first principle of understanding your pet’s needs.

“People treat animals as if they were people, and they treat us as if we were their species,” she says. For example, dogs often bite each other out of play, but owners must reinforce that this kind of behavior isn’t acceptable when playing with people. Work with your pet to manage its behavior so everyone is happy. Make sure your children show mutual respect by not teasing or harming the pet, she says.

An irritated cat, for instance, could scratch its owner and spread bartonellosis, commonly called “cat scratch disease,” which causes swollen lymph nodes in people as well as possible fever, headache and fatigue, according to the Centers for Disease Control and Prevention.

Baseball team’s special canine bat boy dies of lymphoma

Chase the Bat DogChase the golden retriever entertained fans of the Trenton Thunder, a New York Yankees affiliate in New Jersey, for years before his death from lymphoma on Monday. The team and fans threw Chase a retirement and birthday party last week, and last month he was honored at Yankee Stadium. Chase is succeeded by one of his offspring, Derby, who’ll carry on the family tradition of retrieving bats, carrying water bottles to umpires and catching discs in the outfield. The team posted a tribute to Chase on its website.

TRENTON, N.J. (AP) — He doggedly did his work, this pinstriped pooch who faithfully served minor leaguers of the New York Yankees while providing big league entertainment.

Chase, the bat-retrieving golden retriever for the Double-A Trenton Thunder who made highlight reels all across baseball for a decade, has died at 13.

“Chase was there a long time. He put a lot of smiles on people’s faces,” Yankees pitcher Joba Chamberlain, who played in Trenton, said Tuesday night.

“You know it’s going to be sad, but his lineage is carried on. You know it’s something that people are going to miss, but it was fun to be around Chase,” he said.

Chase lived just long enough to be thrown a retirement party by the Thunder last Friday night — featuring Chase bobbleheads, no less. The team said he died Monday.

Chase had been diagnosed in February with a form of lymphoma and had arthritis.

The Thunder’s website Tuesday featured a photo of their late mascot with a bat in his mouth and the caption, “In Loving Memory, Chase That Golden Thunder.”

His bat-retrieving legacy will live on with his son Derby, who continues to be part of the Thunder’s home game entertainment. Another son, Ollie, performs with the New Hampshire Fisher Cats.

Chase made his debut with the Thunder in 2002. He would trot out in the bottom of the first inning to the batter’s box to pick up bats with his mouth and bring them back to the dugout. He also carried a woven basket with bottles of chilled water to the umpires and entertained fans by running down flying discs in the outfield.

At Friday’s celebration, which coincided with his birthday party, fans were encouraged to bring their dogs to the game.

Last month, he was also honored on the field at Yankee Stadium. Chamberlain petted Chase before the game and infielder David Adams came over to greet his old friend.

Adams recalled Chase retrieving his bat, doing it without leaving teeth marks in the wood.

“He’s not chomping at the bit,” Adams said then. “Or at the bat, either.”

Dogs of all shapes and sizes were at Trenton’s game Friday night against Reading, sitting in the stands with their owners. As fans filed in, Chase lounged on the grass outside the Thunder’s dugout on the first-base side.

A tribute to Chase’s career was shown on the video board. Chase was in position near the bench when Eduardo Nunez — who has since rejoined the Yankees — led off for Trenton in the bottom of the first inning. After the at-bat, Chase trotted out, picked up Nunez’s bat and returned to the dugout to a big cheer from the crowd.
