And you never know until the "snap" happens, when it's too late. They are always such "peaceful, loving" dogs for their whole lives - before they go psycho.
I read that dogs of any breed can have ‘lesions’ on the brain that causes unpredictable violence and that the pit variants were selectively cross bred to increase the occurrence/likelihood of getting a dog with that brain deformation. So while the trait exists across dog breeds it has been concentrated to occur much more often in the pit variants. This lesion and the traits selected for the ‘ideal’ pit line included the ‘attack without warning’ trait. So yes, I too know people who have had 2 or 3 pits in a row without incident. But it is Russian Roulette unless you can check your dog’s brain for lesions. I do not doubt that there are pits without lesions or unpredictable behavior but way too many do have those traits and it may only become noticeable under tragic circumstances. Sometimes I gotta wonder if owners who are 100 percent confident of their dog despite the breed description are just unaware of what their dog is contemplating when frustrated or feeling threatened - the breed was developed to give no warning before attack. Like those families who say the dog was cuddly and obedient right up until he flipped out. When I read about this woman, I just couldn’t imagine fighting off a dog pack thinking ‘you mean THIS is how I’m gonna die!?”
