It's very interesting how so many ppl are saying to kill the dog and lock up the owner without fully knowing all of the circumstances of this situation. This breed has three types: 1) the straight pitbull terrier, 2) the Staffordshire bull terrier, and 3 ) the mixed breed. Which one is in this story?
The straight pitbull is a more animal-aggressive dog. The Staffie is a more person-aggressive dog. And the mix is just that, a blend of both. The Staffie and the pit look alike because they are both of the terrier breed, but they are really pretty different.
In the States, pit bulls are used mostly as hunting dogs to capture hogs (do an online search for ' hog hunting with pit bulls'). These hunting dogs killed no owners in those situations and are well cared for. Granted, this terrier breed is special, but it does have a place. So, if we are going to kill all of this breed, we should at least have a better understanding of its personality. And should we also kill all the hog-hunting pitbulls too?
A lot boils down to the owner, though, as with any animal. consider the following search term ( pitbull protects family ), and again, a lot depends on the treatment of the animal, whether dog, horse, elephant, or big cat. In certain situations, this dog, when cared for properly and trained, is your very best friend. Your wife, your children, and all of your property are safe with this properly cared for, loved, and adequately trained dog in your home when you are away. They are not all bad.
Just sharing a more balanced understanding of this breed.
