[Velma And Charlie]

Keeping them permanently separated will not be an option. If it comes down the that, I will have to find Charlie a new home. Neither are neutered (I do understand the differences that can make) but Charlie is going in soon. (We're getting ready to move in a couple weeks and I thought that would be a good time to take him in.) Pasdar is not neutered on the advice of his breeder because he is "show quality" and he may breed (he is just now two years old).

Does anyone have experience in how much neutering could (or could not) change Charlie's attitude towards Pasdar? Or is that kind of like flipping a coin?
