Okay here’s the lay down. Two almost four month old puppies, litter mates (please don’t tell me that we made a mistake), both boys. They’ve always been fine playing until recently, Bullet, the bigger and non alpha one loves to play tug of war, and his bro never had a problem with it! At least until now every time we play Jack (alpha and smaller one) gets mad and bites and attacks Bullet. Are we doing something wrong? But when we play one on one he never seems to want to play tug of war. What’s wrong? And they’ve been fighting each other lately, is this because of the testostrone levels?

I have a 3 year old Jack Russell Terrier and she does this to both of my Saint Bernard’s all the time.When she is laying on the couch one will walk by her when shes sleeping and she will fly off the couch and attack them for no reason they have just learned to ignore it. We just correct her and sit her back down on the floor and she feels bad and then eventually will lay back down and go to sleep. However Jack Russell’s can be feisty most of the time. I have lived with her taking on huge dogs and little dogs. Then she calms down after she smells them. He also could be trying to establish his dominance over his brother which is common if there starting to peak into sexual maturity. Also jealousy is a big factor with Jack’s too. Maybe because your playing tug of war your other dog is jealous and takes it out on your other Jack. My Jack attacks my Saints if I get upset with one of them and raise my voice or when I bring them in from going to the bathroom. I know sounds weird. She attacks growls,snarls, and jumps at them and nips and then leaves them alone. Fixing them may help, but it could be a good case of sibling rivalry that and there Jack Russell Terriers who seem to be little and very feisty most of the time. Big Dog trapped in a little body.

   Socialize your dog when he is young to prevent aggression toward other dogs.
