Help for An Aggressive Dog Toward Other Dog


My 10 month old Jack Russell boy and girl get on lovely, until the boy (Franky) is around food or tired. He gets quite aggressive and sometimes bites. I’ve tried a few training tips, but they have not worked.

I have heard a lot of different things about having a dominant owner or not having one, calm approach or using a scary sound. I am confused and do not know what to do!!

I am wanting to have children soon but do not want to have Franky being aggressive towards them, but I also do not want to give up on him and give him away.

Please help me!!!

Vet Suggestion on Dog Aggression

Hello there,

Since your dog’s aggression seems to be limited to particular circumstances, your first response should be to do whatever is necessary to prevent those conditions from occurring. Aggression associated with food is fairly easy to avoid. Simply separate the dogs at meal times and when you are handing out treats. Never allow food to be present when the dogs are together.The dogs can also be separated when your male is likely to be tired and grumpy. Have separate crates for each of them and institute a couple of nap times throughout the day so everyone has a chance to rest and have some “alone time.”

I am concerned that your male Jack Russell is acting aggressively at 10 months of age. Often this type of behavior worsens as a dog matures. If he is not already neutered, you should consider having that surgery performed. High testosterone levels tend to make aggression worse. If none of these options work for you, it is time to make an appointment with a veterinarian who specializes in the behavior problems of dogs.

Best of luck,

Jennifer Coates, DVM
