Tough Choices About End of Life
Deciding when to euthanize
Not everybody is at ease with the idea of euthanasia under any circumstances, and I understand that. Many people have moral conflicts with deciding to end the life of a pet, no matter what the reason. My perspective is that this is a highly individual decision but that I personally am comfortable with euthanizing my pets once their quality of life is so compromised or they are in such pain that...

Dogs Are Like Children To Us
Science supports what we’ve long believed
Our dogs are our kids. It’s not rocket science—we love them, they love us. They look to us for comfort and care. We call them our fur kids or our four-legged children. So, even though it’s not news to us, it’s validating to see science confirm what we already thought was true: Our dogs are like children to us. Children have been shown to explore the world most confidently if they have a strong...

Dog’s Personalitites
Studies now suggest that personality in non-human animals can be measured and evaluated, just as in humans.
All dogs are the same. really. Look at an evolutionary tree and you’ll find all domestic dogs, clustered together in one spot. But that can’t be the entire story. When asked, Rachel Licker of Lawrenceville, N.J., describes Piper, her “Basset Hound on stilts,” as incredibly goofy, communicative, playful and quick to overwhelm. According to Mary de Vachon of Nice, France, Ria, her Sheltie, is...

Why the Transformation of Wolves to Dogs Remains a Puzzle
The more I consider the continuing debate over the “time” and “place” for the transformation of wolf into dog, the more I become convinced that the puzzle remains unsolved because of human devotion to a simplistic, clever-sounding idea that never made sense in the first place. As first put forth by Raymond Coppinger, that idea was that wolves feeding on the garbage piles of quasi-permanent...

Scientists Searching for Clues to The First Dog
Village dogs’ genetic code may hold clues to canine evolution and health
Like classic twin studies that investigate the interplay of nature and nurture, comparing the genome of village dogs to modern dogs may help disentangle the long-term evolutionary effects of genetic and environmental influences. Mastiff to Min-Pin, Corgi to street cur: all dogs share the same set of roughly 20,000 genes. What makes one dog different from another—or, in the case of purebreds,...

Effects of Diet on Olfaction
Benefits of lower protein and higher fat
It’s not news to anyone that the food that we feed our dogs matters. The right food may translate to better health, proper weight management, longer life, a shinier coat, and better performance in a range of sports and activities. New research suggests that the diet of working detection dogs can even have an impact on their ability to smell. Joseph Wakshlag at Cornell and his colleagues at...

Dogs Lower the Risk of Heart Disease
The American Heart Association issued a scientific statement yesterday that yes, owning a dog may protect us from heart disease. The statement was issued by an expert panel that was convened to look at alternative approaches to combat heart disease. They were prompted to look at the benefits of pet caring because of the growing number of medical studies linking pet ownership to better health. Dr...

Does Reproductive Capability Matter?
Its association with lifespan and cause of death
In a new study called Reproductive Capability is Associated with Lifespan and Cause of Death in Companion Dogs, researchers report on the links of reproductive status (intact or spayed/neutered) with both lifespan and cause of death. Previous studies have suggested that sterilization increases the risk of certain cancers. However, if spaying and neutering actually does increase life span, then...

Fitness Resolutions
Unlike our dogs, who have an aptitude for biting off more than they can chew (if they chew at all), when it comes to fulfilling our fitness resolutions, we might be more successful with a modest approach. Take, for instance, recent findings that only 150 minutes a week of moderate activity (such as brisk walking) can extend our lives by 3.4 years! A daily dose of 22 minutes might seem like a...

Human Point of View
Dogs’ behavior suggests they understand it
Dogs take the human perspective into account when deciding whether to take food that they have been told not to take. This is the conclusion of a recent series of experiments by Juliane Kaminski, Andrea Pitsch and Michael Tomasello described in a research paper called Dogs Steal in the Dark. The experiments all had a similar set up, in which a dog was in a room with a food item on the floor....
