Banned breeds are no more aggressive than others, new study finds | National Canine Research Council

they actually found an INVERSE relationship between size & aggro toward humans.
large breeds were also LESS-likely to be fearful, which reduces the likelihood of a bite.

male dogs were more-likely to be dog-aggro, & there was a slightly larger risk for older dogs to be dog-aggro.

SMALL dogs were more likely to be human-aggro, & also more-likely to be fearful - which adds risk.
