Dog aggression at 9 weeks old. My vet believes a 9 week old puppy should not show signs of dog aggression. She can be stubborn and refuses to walk at times. She will either sit or lay out flat when she does not want to walk. I'm afraid to pull her cause of potential hip issues later. But the vet is concerned cause when she picked up Gabby, Gabby growled and snapped. Gabby began growling and snapping at home when picked up to take outside for bathroom break. She bites on her leash and at people feet or pants legs. She has learned a great deal in the two weeks we had her. She can fetch, sit give paw upon command. She sits at the door before leaving or entering. She sits for her food. She will enter her crate or play pen upon command. She even heels with leash a little. All of this in two weeks. I take her where ever I go so she is used to driving in the car. Just need advice cause we have kids in the house. Don't want Gabby to hurt anyone in our home.
