HELP! My 7Month Old Male GSD is "attacking"
My 7 month old male german shepherd is starting to "attack" my family and i. I read online that it could be puberty. Sometimes it seems like he is just playing and sometimes he Wraps his mouth around our wrists and shakes viciously and wont let go. We have to have someone pull him off when hes doing it to us. HELP please. He has already went through puppy training.
