I’ve owned, practically, all manner of dog (except toy breeds and Dachshunds). They’ve all been working dogs and I’ve never personified them or considered them as “pets.” When you get a dog, you have to familiarize yourself with the breed and its tendencies. Some people won’t let you get near their dogs because they don’t want the dogs ruined for the function for which the dogs were bred. Some people have unrealistic expectations of the animals they obtain as pets. I got my pitbull for a specific purpose (not fighting) but not as a toy! I know this dog. I know its potential and I control it much as I would a tool. Dogs are descendants of wolves and they ought to be regarded accordingly.
Good for you.
