Hello to all! I have a question. I have 1 male, and 2 females bullies. They were all gotten close to the same time, and as puppies. They are all about 2 now. My females have always gotten along, shared everything since being puppies. But when the first female came in heat, they started fighting. Now that hate each other, and I have to keep them seperated at ALL times. I thought maybe a dominance thing over my male, and they'd get over it. I cannot let them around each other at all. Although when one of the females is in the crate, the other will go by and sit beside it, until the urge hits all of a sudden, then it's on...between the crate. They have shared, food, toys, etc., till now. Can this be corrected, and what caused it all of a sudden?!! Thanks for taking the time to read my post!
