If they are not spayed then you should start with that. Hormones can certainly cause aggression. After the surgery it takes about 30 days for the hormone levels to decrease to a level that may change aggressive behavior. If that does not help then you should consult with a professional in-home dog trainer to help you sort out the root of the problem. I see you are in Puerto Rico. There is a HUGE free spay/neuter campaign coming there in November. I suggest you check it out if you want to get your dogs spayed. Search "Spayathon for Puerto Rico" on Facebook to find their page. Hope this helps. Best wishes.
