Sometimes they both need to know who is really tuffer good body slam does wonders usually gives enough time to separate um. But only works when I am there, they have learned not to fight when i am around so they wait till i leave and well they work it out but these are hounds and a cur cross which my cur wins most of the time.
Had the same exact problem when I was 23 morphine didn't even make the pain stop wound up trying the cortisone shot helped a while try that first. Long story short find a good surgen had it fixed and don't regreat it .life to short to be ruined by pain.
