When you have two bitches together, they will show aggression to compete for territory and intact males especially if they are in heat. The best thing to do is to have both of them spayed. This will reduce the aggression between them as it is most likely hormonally related. It will also eliminate the risk of a pyometra, which is a life threatening infection of the uterus. Without spaying them, you will have a very hard time reducing the aggression because it's hormonally related. Removing the source of the hormones is the best way to stop the aggression.

    I'm sorry you are having so many problems with your dogs! Because they are both bitches (intact females), their aggression is likely related to hormones. Intact females with fight with each other for territory and intact males. You don't need to give up one of the dogs if you get them both spayed. This will reduce and potentially eliminate the aggressive behaviors so they can live together peacefully. I would discuss with your vet having both of them spayed as soon as possible.
