I have 2 males, one is 20mths old and been neutered for about 3 months, and then one that just was neutered last week. Right before I got the last one neutered, who is just turning a yr. old, they got into a fight that left both of them bloody around the face. Now any time they see each other they start fighting real bad. Do you think this will change or are they doomed to fight for the rest of their lives? If it continues, I am afraid I will have to get rid of one of them and I love them both but cant have them fight and hurt each other any more. I am desperate for this to stop.
