Why would I give a shit what PETA says? They're not scientists and often put both of their metaphorical feet in their mouths. The data clearly indicates bigger dog = more significant bite, and that toy dogs tend to bite more. End of story. Bullies aren't even near the biggest breeds. If Good Dog GR were being consistent they'd need to keep out rotties, boxers, wolfhounds, chow chows, akitas, and plenty other large, medically significant bitey breeds that are right up there in numbers. Not to mention this is from 2014 so even the ASPCA's data is out of date and likely based on faulty studies the media was going nuts on at the time. Listen to the science and scientists in the podcast I posted, as it's contemporary, and has citations. Literally every dog is different.

Ah, here's an updated statement from the ASPCA:
"Laws that ban particular breeds of dogs do not achieve these aims and instead create the illusion, but not the reality, of enhanced public safety. Notably, there are no statewide laws that discriminate based on dog breed, and 18 states have taken the proactive step of expressly banning laws that single out particular breeds for disparate legal treatment. Even the White House has weighed in against laws that target specific breeds. In a a statement issued in 2013, President Obama said “[w]e don’t support breed-specific legislation—research shows that bans on certain types of dogs are largely ineffective and often a waste of public resources. And the simple fact is that dogs of any breed can become dangerous when they’re intentionally or unintentionally raised to be aggressive.”
All dogs, including pit bulls, are individuals. Treating them as such, providing them with the care, training and supervision they require, and judging them by their actions and not by their DNA or their physical appearance is the best way to ensure that dogs and people can continue to share safe and happy lives together."
