i would like to put him out to stud.where do i start?

You would have to get him sean by owners of bitches. This basically means he would need to be shown. Bitch ownners will be looking for the best quality dog for their girls, with the characteristics especially good in the male where their girls may lack.

A dog doesn't have to be a title holder, but would certainly have to prove to be better than run of the mill, with a decent winning record beating his rivals.
