I have a one year old Original Mountain Cur that I haven't had neutered and I don't think I will. He just might cut it out to be a good stud one day. He is a little small for the OMCBA bench standards, but squirrel dog registries are a little different than, say AKC or something like that. For example, even if a male doesn't meat bench weight standards, they can still place and win the competition hunts and be bred for good squirrel dog pups. Now my pup seems to have everything except some size, that is, conformation, structure, grit, and "tree-mindedness, but his strain is known to be smaller than the others of the same breed, anyway. What I am getting at is if you think he might make a stud one day, and the breeder who knows labs thinks so, too, and if you think you'd like to have a pup out of him one day to keep around, maybe you should wait. You can always make the decision later when you know one way or the other if he really will help the breed in the way of hunting. I wouldn't breed him if he just had "the look," though. Good luck.
