Please consider a few things before deciding to breed him: 1.) If you use him as a stud only, I'm pretty sure you will not have any say in who buys the puppies unless the female is also yours, 2.) you will want to keep his puppies, 3.) you will worry and possibly regret not having him neutered and wonder if testicular or prostate cancer will strike him down. When I first got Harley, I thought the same thing. He was so beautiful and I felt like I might also want to breed him. So, one day one of the techs that worked for my vet wanted to breed her female with him. We put them together twice and it didn't take. I felt like a pimp

And then, I was glad that it didn't take because I didn't know how I would have handled not being able to pick the families that his babies went to. I also would have ended up with another puppy I'm sure, which would have been fine, but I didn't really want two at that time. Come to find out, that girl ended up giving her boxer away because she got a new puppy, a great dane, and couldn't keep them both

My point is, don't do it just because you think it would be fun, it's more emotionally complicated than you realize at first, at least it was for me. I got many requests for Harley to breed over the years, and always said no after that experience.
