Depends. There’s one in my neighbourhood which will, when it sees me coming, wait up (its owner lets it), present its butt to be patted, and then be all over my face sniffing and licking.
What the pit becomes is entirely what the owner makes it.
Precisely-—good owners train and raise good dogs, bad owners train and raise bad dogs.
Look at the number of ill-behaved small dogs in our society-—far too often when one of them displays aggressive or dominant behaviors, their owners will say “isn’t he cute? He’s so funny when he _____”.
