: I have three dogs, all male. Two are Bearded Collies and our most recent addition (two years ago) a Jack Russell. The Jack Russell has adapted very well to our family with one exception. Our fourteen year old Beardie with hip displasia is at frequent risk of being attacked from behind by the terrior. The Beardie in his youth was the alpha of our dogs, but now is a mellow elder, gentle and totally non aggressive. Why do you suppose he is the target of this aggression and is there any way to discourage it?

Response:

Hi Kathryn,
What you may have is a case of Same Sex aggression and Jack Russells are known for it. It doesn't matter if it is two Jacks or one of another breed, it is still two of the same sex. It also may be the fact that the Russells senses that something is wrong with the Beardie, but I just can't tell you for sure. The only true way to keep peace, is to keep them separated at all times.
Sorry I don't have better news for you but same sex aggression can happen at any time no matter if they have been best friends for years. Neutering does help but it isn't a cure all.
