I don't think it really matters if the dogs a perfect example of the breed or not, if you dont intend breeding then neuter, i remember reading a while back a post ( i think it was my fair lacy) when she said something about, imagine having to live with uncontrollable urges to find a female and mate but not being allowed or able to do the one thing your instincts are crying out for you to do, making a male dog live like that when they dont need to is cruel imo
