Good Dog: Studies & Research
Study Places Origin of Domestic Dog in Middle East
A new study of the genomes of domestic dogs and wolf populations has determined that the domestic dog most likely originated in the Middle East. The finding strongly contradicts earlier mitochondrial DNA studies that put the origins of the domestication in East Asia. In comparing the various genomes of different populations of wolves and dogs, researchers at the University of California, Los...

Amazing Facts About a Dog's Ears
Superior Senses: Hearing
Floppy, folded, small, large—dogs’ ears come in many shapes, but they all serve the same purpose: as funnels for sound. Did you know that at least 18 muscles work to tilt, raise and rotate these furry appendages, helping the dog identify and capture sounds from different directions? Here are a few fast facts about canine ears and hearing.   A dog’s level of attention can be determined by...

Different breeds share structure and movement characteristics
In agility there's a lot of talk about the effect of stride length and size on movement, but a new study has found that there may be less variation in basic structure than previously thought. Martin Fischer and his team at Jena University in Germany set out to determine gait differences between dog breeds and the impact joints have on movement. The research used high-speed 3-D cameras to film...

Dogs Have Difficulty “Unlearning”
New research on canine cognition
A recent study published in the journal Animal Cognition shows that dogs have a hard time “unlearning” certain tasks that they have been trained to do. In Minding the gap: spatial perseveration error in dogs, researchers Britta Osthaus, Donna Marlow and Pippa Ducat demonstrated that dogs who have learned a specific sort of detour behavior have trouble deviating from that behavior once the set up...

Are Some Dogs Pessimistic?
A new study addresses this question
In a recent study in the journal Current Biology, researchers assert that shelter dogs who show behavior indicative of separation distress tend to be pessimistic, compared with more optimistic dogs who are less likely to exhibit separation-related behavior. I’m going to explain briefly how the experiment was conducted and then discuss my concerns with the researchers’ conclusions.   In their...

Literacy pups help kids develop a love of reading and writing
As a certified Good Dog Foundation therapy team, Nemo and I have visited our local library many times over the years. During these visits, I’ve noticed that the children develop more confidence every time we see them. We’ve even helped one girl overcome her fear of dogs. In today’s world of video games and television, it’s great to see kids get excited about reading and focus their attention on...

Canine Behaviorists’ Top 10 Issues
By the Numbers
Applied animal behaviorists are constantly developing new techniques, exploring new ideas, considering controversial theories and conducting research. So what is on the minds of the people in this dynamic field? What are behaviorists talking about right now? 1. The prevention of problem behaviors. As behaviorists, we generally deal with serious problems that have been going on for a long time by...

Testing Hips
The standard OFA test may underestimate the risk of hip dysplasia
When we were ready to add a Sheltie to our family, I made sure prospective breeders met a long check list of requirements from socialization to genetic testing. Since Shelties are prone to hip dysplasia, I only considered breeders who screened the parents’ hips. The standard screening model is the Orthopedic Foundation for Animals test, or more commonly known as the OFA. So I was shocked to find...

Mapping the Gut
New research seeks to understand the stomach
My dog, Nemo, is an expert at getting into the garbage and eating treasures off the street.  Fortunately, to date,  Nemo’s dietary habits have been fairly innocuous, but eating bad food can easily lead to more serious conditions, like gastrointestinal infections. Until now identifying canine gastrointestinal disease was difficult because scientists could only culture a small percentage of the...

And Man Created Dog?
Nat’l Geo special explores canine evolution
Recently, I had the chance to preview a National Geographic Channel special, And Man Created Dog (airing Sunday, August 8, 9p.m. ET/PT). This show is about canine evolution; one of our favorite topics! I must admit I had trouble with its title (too human-centric) and its diorama-like reenactments that confidently state scientific conjecture as proven fact. There is also too much of a “golly gee”...
