Spaying might not do anything, and it might, who knows. Are they fighting over spots in the house? Toys? Food? Attention? What is the trigger? Just be prepared, no one should get rid of a dog because its not getting along with another in the house, especially when many pets live a GREAT HAPPY and HEALTHY life in crate and rotate situations. Get some baby gates to give them their own areas in your house/Apartment and keep them separated for a while. Let them relax and get used to not being attacked while living "together".

Once you have that done, and know they can NOT fight and everyone is safe, you should look for a knowledgeable trainer to work on helping you manage their aggression. It will NOT be curable, but you might be able to manage it so they can be around the family at the same time without incident's once you learn their body language and their triggers.
Also pit has only 1 t. And do you even know if its is indeed an APBT
? It could just be a mixed breed dog that looks like what people think a pit bull looks like. My point is, yes APBT
are known to be Animal aggressive, but there are plenty that are not and plenty that are. Each dog is different so just take some time, read through the stickies on here and ask as many questions as you can! We are here to help!
