9: STAFFORDSHIRE BULL TERRIER

The Staffordshire Bull Terrier, also called a Staffie, looks a lot like a pitbull because that’s where its blood line originated from. It was bred way back in 1835 and the line has continued to be bred by many. While they can be trained as pets, they also need to be trained in order to curb their aggression, given that they want to be the dominant one. They will attack when they see fit unless they are strictly taught otherwise.
