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...

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...

Remains of a 33,000 year-old dog found in Siberia
I had watched the dog origin wars as a chronicler of the dog-human relationship for several decades when in 2009 I was approached a young editor The Overlook Press about writing a book on the origins of the dog.  I readily agreed, and the result was How the Dog Became the Dog. Pondering the conflicting dates, places, and theories associated with the emergence of the dog, I concluded that as soon...

Dog Speak: The Sounds of Dogs
More than just noise
A friend suggested that one of the reasons we love dogs so much is that they can’t talk back. But I wonder whether that’s true. Sure, a dog won’t tell you, “You really shouldn’t have that second cookie,” but does that mean dogs are not talking back? Dogs are anything but mute, and while we usually focus on wagging tails and beguiling eyes, vocalizations—among them, barks and growls—provide us...

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 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...
