It is very common for Pitbulls to turn, especially ones that have been adopted after a certain age, but they are not the only breed out there that will turn after they’ve been adopted. Animals are quite different than humans they require less. Of a reaction to turn on their owners people study humans more than they study animals the effect of animals, brains and emotions are not that well known no matter what anyone may say it is true that animals are humans best friend but they have feelings and pain just like Anything else?
