I would like to use my dog, a working cocker, for stud but haven't a clue where to start. I have looked at some of the threads on the forum and see terms used such as "Endorsing", "Green Forms" and "Contracts". Can anyone offer any advice as to how I should proceed, the pitfalls if any, and any issues I should be aware of?

Have a read of the first post on the Breeding Forum of this site.
