Hi, My name is Sue and I own 3 dogs. A 10 year old mixed female, a 4 year old male Rottweiller, and a 2 year old male boxer. For the first year and a half they got along great. Once in a great while the Rottweiller would show some agression by growling when someone walked by him or if someone went out the door and the boxer never showed any aggression. Within the last couple of months the two male dogs have been fighting. At first I noticed it would be over a crumb of food and now it seems to be over a look one gives the other. The fights seem to be getting worse and more frequent. The female is spayed but neither males are neutered but I have one scheduled to be done this Thursday, once that is done the second is going to be neutered. Does anyone think this may help or are the dogs a ticking timebomb. I have children in the house and the dogs fights are as though they are trying to kill each other. The boxer is very trainable but the Rottweiller has always been a little stubborn.
