My spayed bitch gets a vaginal infection on occasion, and that gets the boys (yes, even the neutered one) very interested in her. A course of antibiotics usually clears it up.
I do agree that neutering a large bred dog, like a Mastiff, before he is 18 - 24 months old is not always a good thing. But the dimple fact that he is registered is not a good enough reason to breed him. In addtion, I have a question: what "CKC" are you referring to? If you mean Continental Kennel Club, GET HIM NEUTERED!!! Cont. KC is worthless, and will register a pair of socks if you provide a pedigree.
If you mean Canadian KC, you can show him, if his breeder considers him show quality. But I would discuss this with the breeder, as he/she would probably want to help you in any breeding ventures anyway.
But if he is not to be shown, or bred responsibly, please do get him neutered.
