Facial Recognition by Dogs
They respond to photos of familiar faces
You know your dog knows who you are, right? That enthusiastic greeting when you come home is proof positive that he recognizes you. But what clues him in to your identity—the sound of your footsteps, your voice, your unique smell, that palpable charm? That may all be possible, but recent evidence suggests that dogs can actually recognize faces. The ability to recognize faces is important for...

GMO: Are genetically modified crops safe in your dog food?
A vet speaks out on genetically modified pet food.
Most dogs now dine on some type of genetically modified (GM) food, often in the form of corn and soy in their kibble. As these ingredients increasingly enter the food supply, we have one more reason to wonder if our shopping choices might be harming our pets. More animal feeding studies are needed, experts say, and a recent long-term, peer-reviewed report points out why. It found that a diet of...

Dogs Can Sense Earth’s Magnetic Field
It influences their orientation during elimination
A new study called Dogs are sensitive to small variations of the Earth’s magnetic field published in the Journal Frontiers in Zoology has demonstrated that dogs can sense and respond to magnetic fields. It is the first time that this has been shown in this species. Researchers found a measurable change in behavior based on the conditions of the magnetic field. Specifically, they found that under...

Book Review: Decoding Your Dog
Vet Experts Tell Us How
Did you know that the American College of Veterinary Behaviorists (ACVB) has fewer than 50 members? To obtain board certification in this specialty, each has gone beyond a DVM to earn various degrees in applied animal behavior, and has completed a rigorous training program as well. Decoding Your Dog (Houghton Mifflin Harcourt, January 2014), with sections on canine behavior written by 20 ACVB...

Making a Case for Dogs’ Personhood
In a recent  New York Times, Gregory Berns, a neuroscientist and the author of the excellent new book, How Dogs Love Us, writes an intriguing and engrossing editorial, “Dogs Are People, Too” (which was the top “emailed” article in the NYT the day it came out!).  Berns and his team at Emory University have been testing dogs, the first of which was Berns’ own rescue dog, Callie, using functional...

Egyptian Dog Mummy Had Parasites
Those little pests are nothing new!
Mummified dogs are not a new archaeological discovery, but finding bloodsucking parasites on them is. Over 400 dog mummies unearthed from the El Deir excavation site in Egypt have been found, and one young dog among them was infested with a number of parasites that have been preserved. There were over 60 ticks found on this poor dog and there was one louse, too. The scientists who found this dog...
Dog Culture: Science & History
Body Language
Breeders, judges and historians talk about breed standards—why they work and when they don’t
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...

The Animal Behavior Society Conference
Many presentations featured dogs
Last week, the Animal Behavior Society conference was held in Boulder, Colorado and was attended by hundreds of scientists. Besides being the 50th annual meeting, this conference was notable because of the strong representation by people who study dogs or work with them in other ways. I first attended an Animal Behavior Society conference in 1994 and I remember no talks or posters about our best...

Disagreement About Dog Domestication
Conflict among scientists who study it
Research about canine genetics and the domestication of dogs is an exciting area of study with many players, so it should surprise nobody that there is disagreement within the field. Multiple groups of researchers from around the world have compared the genomes of dogs and wolves. While they generally agree about the genetic changes that have produced differences between dogs and wolves, their...

Disadvantages of Pet Store Puppies
Unfavorable behavior compared to other puppies
In a study of over 6000 puppies, researchers found that the behavior of puppies purchased from pet stores was less desirable than the behavior of puppies obtained form noncommercial breeders. Specifically, there were 12 areas in which pet store puppies’ behavior was unfavorable compared with puppies from noncommercial breeders and two areas in which their behavior was similar. There were no...
