I’m a dog lover, but I never trust anyone who tells me how gentle and sweet their dogs are, no matter what the breed.
Too many people are irresponsible with their dogs. They do not respect the potential that all dogs have to do harm.
Anyone who insists their pittie wouldn’t hurt a flea is irresponsible. I’ve had big dogs and small dogs, all highly trained and lovingly raised, and I would never be so foolish as to say they were guaranteed harmless.
