Breed gives a loose guideline for what kind of behaviors to expect, like how hounds are more inclined to be howlers, “but it’s certainly not a hard and fast rule.”
“Everybody was assuming that breed was predictive of behavior in dogs,” geneticist Elinor Karlsson of the University of Massachusetts Chan Medical School in Worcester said in an April 26 news briefing. But “that had never really been asked particularly well.”and found that genes could explain some of the differences between, say, poodles and chihuahuas . But Karlsson and her colleagues wanted to learn how much breed can predict variation in individual dogs’ behavior.
Studying mutts also makes it easier to decouple traits from one another, says Kathleen Morrill, a geneticist in Karlsson’s lab. “And that means on an individual basis, you’re going to have a better shot at mapping a gene that is actually tied to the question you’re asking.” they could provide, such as hunting or herding . Today, these selections still show up in breed groups. For instance, herding dogs on average tend to be more biddable and interested in toys. It also follows that, within breed groups, individual breeds are more likely to display certain motor patterns: Retrievers, unsurprisingly, are more likely to retrieve.
