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 Dogs Understand Our Words?
Say What?
“This is not your food! Don’t even think about eating it. This … is … not … your … food.” What do our words mean to dogs? Not that I’m about to stop speaking to dogs anytime soon, but I do wonder what my daily utterances signify to Millie, Piper, Upton and Finnegan, the dogs I converse with on a regular basis. Do I sound like a cross between Charlie Brown’s teacher and Gary Larson’s “What Dogs...

Study finds Hormone-disrupting Chemicals Leach from Some Plastic Toys
The toy aisle is meant to be all about fun, but recalls, toxic imports and a dearth of regulations have left dog owners facing tough choices. Many toys are made of plastic and may contain chemicals that interfere with hormones. A new study by researchers at the Institute of Environmental and Human Health at Texas Tech University shows that BPA and phthalates, chemicals that disrupt hormones, “...

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...

New Treatment for Paralysis
Dogs walk again after spinal injury
In an exciting development in the treatment of spinal cord injuries, researchers at Cambridge University were able to restore some movement to the legs of dogs who had been paralyzed. (All 34 dogs in the study had become paralyzed by injuries or accidents. No dog was purposely injured for the research.) The breaks in the spinal cord were at least partially fixed with the use of cells from the...

Whisky - Bionic Dog
Something was wrong with Whiskey, and it wasn’t lethargy, whining or refusal to eat that tipped off his owners. It was chew sticks, unchewed. For the 10-year-old Small Munsterlander, chewing was a lifelong obsession. It had been a good life, one spent running down San Francisco city sidewalks; playing in the parks; exploring neighborhood shops; and, of course, chasing toys on the beach. Whiskey’...

The "D" Word: Dominance
We talk about dominance, but do we really understand it?
If a dog has behavior issues such as a tendency to mount other dogs, any form of aggression, an overly pushy play style or poor response to training, some people are sure to claim that “dominance” is the culprit. But are they right? The ongoing dialogue about dominance in the dog world is more problematic than an unattended puppy in a shoe store but it’s unlikely to go away anytime soon. While...

Are Dogs’ Mouths Cleaner Than Humans’?
Young Scientist in Action
Abby Walling & Lucy
Are dogs’ mouths cleaner than humans’? Her grandmother said they were, her mother said they definitely were not. Not one to take things at face value, Abby Walling of Iowa City, Iowa, decided to conduct an experiment and answer the question once and for all. Not only did she reach a conclusion, she won a 2011 Young Naturalist Award from New York’s American Museum of Natural History for her work....

Education: Gone to the Dogs
Canines claim their territory on college campuses
Summer has faded into fall and it’s time for dog lovers — and dogs too — to head to college, where dogs are taking their place in the dorm, the psych lab and even the classroom. While some dogs simply kick back and enjoy campus life at a university with pet-friendly housing, such as Eckerd College in St. Petersburg, Fla., or Stephens College in Columbia, Mo., others give their intellectual...

Dog Training: Operant Conditioning
When operant conditioning clicked (and clucked)
On a warm and slightly overcast morning in 1967, a rusty, mustard-colored station wagon slowly approached the terminal at San Francisco International Airport. Wheels still rolling, a door opened and something gray jumped out. As the wagon continued on its way, an animal headed toward the terminal. It was a cat. Straight five steps, then wait. The glass door opened and as a portly man in a...
