I love pit bulls and Ive been around both loving and aggressive pits. So I think it really depends on both of the dogs. In my personal opinion I have always felt that a female pit can be a little more temperamental then male pits. Put it this way me and my brother used to live together and he had a female pit named Ayla. Ayla was raised from a puppy and was sweeter than sugar(Her boyfriend was my Chihuahua) then I rescued a 8 week old female pit. After nursing the pup back to health I began to let her socialize with Ayla. One day I came back from the store and when I was unlocking my door I could hear the sounds of a fight. I walked in to find my pup pinned to the wall by Ayla. When we separated the dogs there was blood every where and Ayla had not only crushed my pups ribs but also separated the spinal cord from her spine. It was a sight I will never forget, so I don’t want that to happen to you. I’m not trying to discourage you but you need to think of them like pairing up human roommates. Are both dogs dominant? If one dog was to get aggressive would the other surrender? Are they too much alike or too different? Just think it through carefully.
