(5,764 posts)However Pit Bulls are NOT in the more aggressive (as far as "more aggressive" even goes, which isn't actually all that far) group among dog breeds.
They are in fact *below* average for aggression towards people when factors of training and environment are properly controlled for.

That black line is the mean across all breeds studied.
The "highly" aggressive breeds were daschunds... terriers... beagles... chihuahuas... but nobody give a crap because they're small and cute and generally not scary. I have a beagle, I love beagles, but yeah they've got a higher tendency to get bitey and you have to watch it IN THEIR TRAINING.
It's almost *all* down to training and owner conduct.

Pits are above average for aggression towards other dogs, but again "above average" isn't all that significant a value here and AGAIN, it all comes down to training. This "Pits are an inherently dangerous breed" stuff is 100% pure *myth*. Pit owners have a tendency to be dangerous dog owners, because they pick pits because they look big and scary and then they MAKE them aggressive.
