Just be prepared for your little male to possibly "change" after using him as a stud. I don't have a lot of experience with this - not enough to say for sure that it WILL happen - but I used my male toy poodle years ago one time to breed and if it weren't for such cute babies that came out of the experience, I would have totally regretted it. The worst part was his marking habits afterwards. He got really bad at that and that's one of the drawbacks I've heard about stud males. Just check into that and be well-informed before you choose to use your pet to breed.
By the way, that little boy of yours is adorable! If I was looking for a stud (for Tatum, of course
) based only on looks, he'd be way up on the list!
