Agressive Female English Bulldog

Question
We have a 1 and half year old female English Bulldog, who was just fixed, along with a 10 year old White Female Boxer. They do play together, however, the bulldog has become very aggressive towards the boxer. We had fixed thinking that she would calm down; no such luck. She attacks the older dog a couple times a day; b;lood is occassionally drawn. We love both the dogs. What is the remedy?
Both these were rescue dogs.

Answer
Unfortunately, the best way to resolve this is to let them duke it out as terrible as it sounds. Obedience classes for both would definitely help the situation. At least you would be able to "call them off" when they got too rough.

Females can be miserable. That's just the way it is.
