My Jack Russell Maggie May is 9 months old. I am worried that she might be showing aggression. She growls and tries to bite me if I pick her up on my terms or if I try to groom her, even just brushing. I also have a two year old wire haired terrier and they are very possessive over me. They get into fights to where they will not release their grip on each other. I have been bitten by Maggie while trying to break up the fight. Any advice would help.
