Can you tell what starts the fights? Is it over toys? Is it over food? Is it over attention from you? Is one dog invading the other's space?

I had a toy hoarder, and a behaviorist gave me a few pieces of advice that may or may not be applicable to you. Here are her main points:

1. Exercise them until they are dog tired.
2. Since our problem was over toys, she had me scoop up all the toys in the house and only give them out when I was there to supervise.
3. During toy time, she had me leash the aggressor. I played with both dogs normally and made it a lot of fun, but the aggressor was on a leash.
4. When toy time was over, I put all the toys away.
5. I didn't unleash him for about three weeks, and only after he stopped pulling at the leash to get the other dog.
6. Eventually, the aggressor stopped hoarding all the toys. I was amazed.

You'll have to use your own judgment on whether it sounds like those things might help in your situation. It's probably not a great idea to accept anyone's advice who's not a professional. And that I'm not.
