German Shepard Pitbull mix
I have a 4 month old puppy. She isn't potty trained and seems to only have accidents out of defiance to me. She has started growling and biting at everyone whether they're playing with her or greeting her or whether I'm punishing her. She doesn't listen to commands except for sit (cuz she gets a treat). She was a rescue situation so giving up on her doesn't feel right but I'm at a lose with her. We're doing puppy training classes now but don't seem to be helping at all. Please help!
