Here's an interesting study that came out in 2010 comparing the perceptions, behavior and training of larger versus smaller dogs ("Behavior of smaller and larger dogs: Effects of training methods, inconsistency of owner behavior and level of engagement in activities with dogs." Arhant et. al. Appl An Beh Sci 123 (2010), 131-142.) There's a lot in this study, based on 1,276 questionnaires, but the part I want to talk about today relates to owner's perceptions of dogs of different sizes. I'm always suspicious of data from surveys about behavior, since what we think an animal does and what it really does is often not the same, but because these surveys were about perceptions as well as behavior they definitely have some merit. The authors found that, as they summarize in the abstract, Read More

Clever Hans Revisited
You probably know the story of Clever Hans, the horse owned by a math teacher named von Osten who decided to teach his horse to do math in the same way that he did his pupils. After extensive training, Clever Hans appeared able to solve relatively advanced mathematical problems, including multiplication and long division. Clever Hans showcased his abilities around Europe, although von Osten never charged for an exhibition. His owner and trainer sincerely believed that his horse understood what he was being asked, and wanted the world to see it for themselves. Scientists were so interested that a panel was formed, led by psychologist Carl Stumpf, which verified that no tricks were visibly involved, but passed the issue onto psychologist Oskar Pfungst. After an extensive series of tests, Read More
Best. News. Ever.
Today, it's all about the farm. I had a blog written about the effect of acoustic environments on us and our dogs, some new products available for us to use to calm our dogs, and some new results of "calming" music that Katie and I have seen with our dogs. And then I erased it all with one key stroke. I'm sure that has never happened to you.... So I'll save that topic for later (and promise to catch up in the next month or so on other topics I've promised you, like exercises to calm the sympathetic nervous system, and the methods of the clicker versus no-clicker study ). Right now I have to get home to the dogs and work on the talk that Karen London and I are giving at the Interdisciplinary Forum on Applied Animal Behavior next week in Phoenix. So here's the second half of the blog, Read More
You’ve Got a Friend?
If you've been following last week's blog and the comments, you know that there's been an active discussion about whether dogs can (or can't) form "true" friendships. This was motivated by an article in Time Magazine by Carl Zimmer that discussed the evidence of friendship in several species of mammals, including dolphins, baboons and horses. In spite of the irony of a cover photo that includes two dogs (and the photographer saying: "I actually had to make sure that the dogs coming in were actually friends."), the article states "... most scientists think they [relationships between dogs] fall well short of true friendship." I'm curious who the 'most' scientists are... I suggested to the author that he might want to talk to scientists who study dogs like Barbara Smuts & Camille Read More
Do Dogs Form “Real” Friendships?
I had an entirely different blog written and about to be posted, but there's a swirl of discussion going on right now about an article that came out in Time Magazine by Carl Zimmer about "friendships" in animals. He has lots of good information from researchers who argue that true friendships are formed in many social species, including horses, dolphins, and baboons. I was a tad irritated at suggestions that "we" (scientists) haven't accepted that friendships can be found in other animals until just recently..." look at the writings of Jane Goodall and Frans de Waal for example for exceptions to that... but in general it's a truly good article. But imagine my surprise when he writes that evidence of true friendships can not be found in dogs. He says: ".. most scientists think Read More
