my almost 6 month pitbull growls like shes killing someone when we play tug of war which i have stopped playing since the growling started but somtimes if shes playing with her stuffed animals she growls with them and stuff. she never growls toward me or any other animal or human. just wondering how to stop it so she doesnt take it to seriously and some tips of how to get her to drop the toy when i saw drop thanks guys!
