Environment and socialization remain the largest determining factor.

Unsurprisingly, most stereotypes about dog breeds are pseudoscience that come from the eugenics movement. In particular, “popular knowledge” around pitbulls and bulldogs is just thinly veiled racism.

The research did find some genes associated with traits like human sociability and howling frequency. But overall, only around 9 percent of dog behavior was explained by breed.

“Dogs are individuals,” said Marjie Alonso, a study author and executive director of the International Association of Animal Behavior Consultants. “What a dog looks like is not really going to tell you what the dog acts like.”

Edit: modern “purebred” breeding literally came from eugenicists, that’s why this old political cartoon even exists. Documentary on pedigree dogs and their many issues: https://vimeo.com/166015460

    I kinda agree that written survey stuff is pretty weak. But like everything else in our stupid lives, dog breeds have somehow become political. And people absolutely make snap judgements about breeds and their owners based on racist and classist assumptions. I would generally agree with a study that found training/upbringing has a stronger effect on breed behavior than genetics because otherwise there wouldn't be a whole subculture around rehabilitating dog rescues.
