My memory has come back! LOL
When I was younger we had a Lhaso Apso mix and we had our female GSD/Husky mix and they did fight, the female used to make puncture marks in the males head. The male was the one that started it, he would usually growl when he was eating or chewing a bone or playing with a toy and the female would go after him and win the fight everytime.
