Is your other dog neutered?
If he isnt Id say thats the main problem.
I have two males that always got along. THey are studs. When the younger one starting coming into sexual maturity, the two started trying to beat the tar out of each other and can no longer run together.
Im not sure since this problem has already started if it would change of neutering of your older dog if he isnt already. BUt if you want to keep your yorkie boy, neutering of your other boy might (I say might) change things. |
