Not in my house I have 6 dogs, 4 girls and two boys. Three of the girls are inside dogs and are all spayed and we don't have any problems. I'm not going to say there aren't disagreements sometimes but no serious fights. Actually we mostly had girls while I was growing up and they never fought. So I don't think it's fair to say that females will always fight, but it is possible for two dogs to just not like each other. |
