Training Tips to Stop Dog Biting Owner and Family

by Louise and Suggestions from Our Veterinarian

My 13 month old Jack Russell bitch has started to bite me, she will not look at me and growls when I go near her. She has bitten me twice and I really am worried about it. She has been spayed.

Having a young daughter and grandson I am extremely worried about her behaviour. What reasons could there be for her sudden change? I am the one who walks her, feeds her and usually plays with her although lately she has not wanted to play.

Vet Suggestion Jack Russell Dog Biting Problem

Hi Louise,

At 13 months of age, your Jack Russell is reaching adulthood. This is the time when we’ll often see problems with aggression start. In the short term, you need to do whatever is necessary to keep you and your family members safe.

Avoid the situations that seem to bring about the dog’s aggression. Whenever she acts in that way, the behavior is reinforced. If you have to crate her when your daughter and grandson are around, do so.

I strongly recommend that you make an appointment with a veterinary behaviorist. He or she can diagnose the causes behind your dog’s aggression (e.g., fear, dominance, guarding food, etc.), design an appropriate behavioral modification protocol, and even prescribe medications that can help her deal with her “issues.”

Best of luck,
