In South Central Texas, it’s Rockweillers s/. But sarcasm aside, the Pit bulls have been getting a very bad rap mainly due to the idiot owners. Your run of the mill Pit Bull should be extremely friendly with people, you just have to watch them around other dogs. Also, the Rotties are great if they don’t come from a backyard breeder, the German stock love people.

Given these dogs were loose, I’d say it’s a safe bet they had an idiot owner as well.
