Q: I have a 5-year old Pekingese and a 10-year old Wire Hair Fox Terrier. The Pekingese is subject to seizures and bouts with a collapsing trachea. The Pekingese is no doubt the boss--most of the time--in the house between the two, but whenever she has a seizure--which is not that often and is on medication for-- or an episode with the collapsing trachea, the Terrier will become very aggressive and act like she is attacking the Peke. When I try to pick the Peke up at these times, the Terrier will keep biting at her and try to grab the Peke's tail. I have to forcefully push the Terrier away. Is this just a trait of the Terrier? Normally she is a pretty laid back, non-aggressive dog. Also, once in a while she tries to show her dominance over the Peke, but the Peke always strikes back and ends it fairly quickly. Thanks for your comments.

A: When one of them is a Terrier, keeping 2 female dogs together can certainly lead to fighting. It sounds like these two do better than would normally be expected a lot of the time, but when the Peke has an episode, the situation deteriorates. I would not leave them alone together because serious aggression can and sometimes does erupt toward a dog who has a seizure or other medical event when kept together with another dog, sometimes to the death. This is just nature taking its course, not viciousness on the part of the other dog, but I'm sure you do not want that to happen to your Peke. What's even more likely with a Peke is that she could lose an eye.
