It’s a breed. Controversial subject that shouldn’t be IMO as the dogs are dangerous as Hell. There is no knowing when they are going to go off. It’s the not IF thing, it’s the WHEN thing with them. They are nuts.
I take the bus to work every morning but drive my car and park closer to the stop. Someone just moved in the end apt. on the street and have a pitbull. The first time I passed he was on a lead from his dog house in the back yard (small) and he was straining/lunging so hard, I thought he was going to break it. Needless to say, I was terrified and got to my car as quickly as possible. Yesterday he was at the second floor window and was barking at me again. I don’t know where I can park where I don’t have to pass this “thing”.
His son has one, and he swears based on his experience with that one dog, that they're no different from Golden Retrievers...that the bad ones are completely the result of how that particular dog was treated and/or trained.
I tell him he's nuts, and needs a broader education on the subject.
There might be an occasional aggressive Golden Retriever, sure, but it's a shock to hear about. No one is shocked when there's a dog attack and it turns out to be a Pit Bull. That's what they see as doing their job. It's in their genes.
