My post from an earlier thread;
““Pit bulls are not naturally mean dogs. If they are mean it’s because some human made them so. “
Not so! Their genes tell the tale. So do the horrible scars on my friend’s leg, the result of his Staffordshire suddenly attacking him whilst he was on the phone talking to a friend. Daisy had been a very lovable, and well loved, dog, until she suddenly snapped. They are a very dangerous breed because of what they carry in their genes.”
My standard reply is, then train Shelties to point & retrieve; a beagle to herd sheep, and an Irish setter be a police dog: why do their genes predispose them to what they were bred to do, but a pit's don't?
They never have a coherent answer.
The inability of many people to admit to themselves that there is a lot of a dog’s behavior that is hard wired is unreal.
I’ve seen it personally most notably with a lab who was swimming and fetching the first time she encountered water when only a few months old, and very little training other than chasing tennis balls. Anyone with any sense looks at the history of what pits were bred for, vs. labs.
By your own admission she was not a naturally mean dog
but rather a naturally loving dog until something triggered an attack.
