I have two puppies. Both are very very sweet. Lately one of them has been acting "aggressive" or "irritable". She loved music since day one. And I used to hold her on my lap and make her "dance" ( just move her arms slightly up and down) and sway her body. But today... She responded with a bite to the face! This wasn't my first incident since I've taught her biting isn't tolerated. I was laying with my other puppy and she ran up started growling then bit me...She stopped biting and recently restarted. It can't be Aggression because she only 3 months but why would this happen? Is she throwing a puppy tantrum? Maybe I bugged her ? She HAS grown out of biting hard during play as well. Soni know she wasn't playing because it hurt!
