Ya know, before I went to have Bower neutered I asked what habits he may develop afterwards. The vet didn't really say much so I asked people I knew that had neutered their dogs. One told me that he will start mounting anything, male or female. It hasn't happened yet, I am not even sure if it's true but I have never seen a female mount a male. Then again the only female I ever had was one we fostered for about a year but they never had her fixed so I am not too sure.
