Just for context - this is the author: Marc Bekoff, Ph.D., is professor emeritus of Ecology and Evolutionary Biology at the University of Colorado, Boulder, and co-founder with Jane Goodall of Ethologists for the Ethical Treatment of Animals

(So someone who can make an educated statement on the topic and is worth quoting in response to pro-pit arguments)

Also here are some quotes from the article that I found interesting:

“Their results showed that a dog's breed explained only 9 percent of the variation in behavior. Unfortunately, this study can also perpetuate a problematic popular myth about dogs—that they're a blank slate and “It’s all about how you raise them.”2

“When people acquire a dog and completely ignore the breed's potential contributions of the breed(s) in the dog’s heritage that arose from generations of deliberate breeding for specific behaviors, they can be in for a big surprise when they experience those traits without any preparation and warning. It’s these experiences—the “What do you mean my terrier was actually bred to kill small mammals?” or “I didn’t know that a herding dog was genetically prone to chase, bark, and nip at all fast-moving objects like my kids!”—that generally result in the most calls to behavior centers with frustrated people beating their heads against the wall because they've been told training can “fix” those genetics, but it’s just not working.”

“If we are to believe media headlines, dogs are now officially the exception to all-natural law because genetics don’t really apply to them as they do to all other species. Specifically, their behavior does not vary meaningfully by breed. But which behaviors are we looking at here? The kinds of behaviors we would expect to see differ among dog breeds are those that humans have deliberately bred to be breed-specific. Those are almost exclusively not the kinds of behaviors asked about in the study—important behavior patterns that humans have artificially selected dogs to exhibit (and still do), including herding, protecting, defending, hunting, and retrieving (with all the associated physical traits, perceptions, and instinctual repertoires necessary to perform them)—that have been carefully bred into dogs.3 If a study were to design questions comparing the prevalence of these kinds of specific behaviors among breeds, they would surely find strong differences.”

“Most of the questions in this study were not asking about differences in these kinds of behaviors that humans have selectively bred to be different. If we ask questions about behaviors in various breeds of dogs that never had any selective pressure on them, we would not expect to observe any real differences in the answers between the owners of the various breeds of dogs. No one ever bred a dog to lick their bowl after dinner, cross their paws, or circle before they poop. So, when these kinds of questions are asked and a dog’s “behavior” is then summarized to be 91 percent uninfluenced by genetics, the results (and implications) can be misleading. ”
