Female litter mates, 13 mos starting to fight
Disclaimer-I know now that it was a bad idea to get these monsters as litter mates, I got them out of grief and wasn't thinking clearly.
They get along quite well, some spats here and there. Now we have had a couple of serious fights. They compete with each other quite a bit. When I started reading up on it, they are doing all the typical things to dominate each other.
When they start, what is the best way to handle it? What is allowed and what isn't?
Thanks in advance
