I have a similar problem, I have 2 males both neutered, Hobbes is 20 months old and Calvin is 14 months old. They are brothers from diffrent litters. I also have a 22 month old female Tessie. I got all of them as puppies. Hobbes is very loving and laid back , but at times he will all of a sudden growl and attack Calvin for no reason, then Calvin will fight back. Several times I have gotten caught in the middle and so has my husband. We always push Hobbes down from our laps and look him in the eyes and tell him NO. He understands but continues to do this with no warning. Hobbes is 15 lbs and Calvin 8 lbs. They never do this with the female because she won't tolerate it. I now have an 11 week old female (same parents as Calvin and Hobbes). He has shown some aggression towards her. I didn't mean to take over someones thread but didn't want to start a similar thread. |
