Yeah, I hesitate trying to give advice when it gets that serious too. The best thing you could do is hire a behaviorist. They're expensive, but a lot cheaper than the alternative.

Can you tell what they are fighting over? Is it over possessions like toys? Food? Your attention?

I have a toy hoarder. He's attacked everything from his 4-pound brother to an 80-pound border collie. A behaviorist I met online gave me a bunch of things to try. They've helped but haven't solved the problem completely. For what it's worth, here are the main things she told me.

1. Become pack leader. For me, this meant taking control of the toys in the house. Hand them out. Pick them up at the end of the night. Teach them that they are my toys, not theirs.

2. Tire them out. Fighting often means excess energy, and if you can really tire them out, they are less inclined to fight. She even told me to consider putting weights (like a roll of quarters) in Eddie's coat during walks to tire him out a little more.

3. Leash my aggressor during toy time. (This won't necessarily be good advice for you unless yours are toy aggressive too.) Do this for several weeks every time you give them a toy.

Good luck. It's a serious problem.
