Exploring the Microscopic Ecology of the Microbiome
Investigating the microscopic worlds in our dogs may reveal pathways to better health.
The microbiome is the invisible world of the hundred trillion bacterial, viral and fungal microbes that live on us and in us—on our hair and skin, behind our ears and inside our eyelids. The bulk of these miniscule microbes are good guys, gut microbiota that congregate in the digestive tract, where they bolster the immune system, manufacture vitamins and digest food to generate nutrients and...

Digging Up Bones
What can archeology tells us about the “connection” origins.
Studies of prehistoric dog burials have been making splashy headlines lately. Although the popular press would have us believe that these finds are proof of the affectionate relationship our ancestors had with dogs, the unifying theory that gives meaning to burial patterns remains elusive because ancient people left no written record. What little we know about dogs’ social roles in antiquity is a...

The Difference Between Guide Dog Breeds
In honor of national guide dog month, I'm reprinting excerpts of an interview I did several years ago with seven experienced blind people who've used guide dogs most of their lives.  Here they compare problem solving strategies between 36 dogs representing six breeds.  Compared to my usual posts, it's a lengthy conversation, but if you've lived with a Lab, Golden, German Shepherd, Aussie, Border...

Saint Bernard current and past
In the world of mammals, the domestic dog— Canis lupus familiaris, a subspecies of the gray wolf— reigns as the most morphologically diverse. Consider, for example, the extremes represented by the 155- pound South Russian Ovcharka and the seven-pound Silky Terrier. This incredible variety can be attributed in part to the dog’s basic template, which can be customized by the manipulation of a very...

Saving Street Dogs in Havana
One dog at a time
For Havana's dogs, it's not the best of times, but it's not the worst either. Some improvement is due to the efforts of the non-governmental Cuban Association for the Protection of Animals and Plants (ANIPLANT), an organization focused on improving the lives of dogs and other animals in Havana. Founded in 1988 by Cuban entertainer Maria Alveres Riso, and Cuba's first prima ballerina, Alisia...

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,...

Behavioral Differences Between Dogs and Wolves
Dogs and wolves share a similar genetic profile. So why are their behaviors so different? The reasons aren’t clearly understood. In a recent paper in the journal Ethology , evolutionary biologist Kathryn Lord's doctoral research (University of Massachusetts, Amherst) suggests differences in later behaviors might be related to the pups' earliest sensory experiences during the critical period of...

Latest Genetic Research about Dogs' Diet
“Where goeth the food, so goeth the dog.”  (old proverb) The earliest archeological evidence dates dogs to about 14,000 years ago. Remains of small dogs in Israel go back 12,000 years. When people settled down in agricultural communities, they began to tinker with the natural environment, bringing about modification, intentionally or accidentally, in plants and animals. Of course dogs joined the...

Do DNA Tests Reveal Genetic Secrets?
The Beauty of Diversity
For those of us who love dogs, using DNA tests to deconstruct our mongrel pooch’s mysterious heritage is appealing because we want to be able to answer the question, “What kind of dog is that?” Companies say that DNA-based diagnostic tests, which sell for about $60, can answer the question by comparing your dog’s DNA to over 100 of the most popular breeds. But are the tests accurate? I decided to...

Rabid: A Cultural History of the World's Most Diabolical Virus
Rabies is a relentless killing machine that exploits the very thing we love most about dogs, their sociability with humans. The virus kills 55 thousand people a year; unless bite victims are treated before the onset of symptoms, the pathogen’s mortality rate is nearly 100 percent. According to the World Health Organization, dogs continue to be the source of human death in 99 percent of the cases...
