Alright.

This is from the NHS:

Abstract: A Review of Dog Bites in the United States from 1958 to 2016: Systematic Review of the Peer-Reviewed Literature

"Since 2001, Pit Bull type breeds have accounted for the largest subset of dog bites reported in the medical literature (37.5%), with mixed breeds (13.3%) and German Shepherds (7.1%) accounting for the 2nd and 3rd largest minority groups during this same time period. In addition to these findings, we evaluated the effectiveness of breed specific legislation in Denver, CO, the largest jurisdiction in the United States with a pit bull ban in place. Since 2001, 5.7% of bites in Denver, CO were attributed to Pit Bull type breeds compared to 54.4% in the remainder of the United States."

Notably you'll notice that a ban, not even just proper cage and muzzle regulation, was the result of an ~89.5% reduction in pitbull attacks (1-(5.7/54.4)).

This is from a paper on the effectiveness of Pit Bull bans and the human factors involved in the breed's behaviour:

Pit Bull Bans and the Human Factors Affecting Canine Behavior

It says, among other things: "Health professionals and animal behaviorists point out that breed is only one of "[s]everal interacting factors" that determine a dog's likelihood to attack. 21"

Meaning this paper acknowledges the role of breed as a confounding genetic factor affecting dog aggression.

Digging into that link they provide for this claim, we find,

Breeds of dogs involved in fatal human attacks in the United States between 1979 and 1998

"As in recent years, Rottweilers were the most commonly reported breed involved in fatal attacks, followed by pit bull-type dogs"

You can doubt the authenticity of the studies I've listed all the way down, bringing up allegiances and ulterior motives, as well as statistical inconsistencies due to missing data about the exact number of Pit Bulls in the US.

Here's one final nail in the coffin, look at the following article:

Breed differences in canine aggression

This shows clear as day differences in aggressive response by dog breeds.
