Well it could be a crap shoot because you never know what kind of personality the new addition will have. However, if all things check out medically, then training the male yorkie to fit in would be what you would have to do.
I had to train my new female yorkie to not chase the cat. They hated each other and they did not get along. But with a lot of patience and training they were able to co exist. They weren't best friends but they didn't kill each other.
If you get a new male especially a puppy (who are very playful) training should (hopefully) fix any behavioral issues. |
