The first question that needs to be answered is why do you want to put him at stud?
You will find plenty of breeders here in this forum. There is another section just for breeders.
Since we are a breeder, here is my opinion.
The first thing to consider is the bloodlines. A 100% purebred EBD, AKC registered, does not make a stud dog. With so many studs to choose from, the pedigree needs to be considered. A local CH in the top and bottom lines could be from a local or even regional shows. Alternatively, to have world champion, international multi champion bloodlines make for a better stud.
While showing is NOT necissarily needed, it does show that you believe IN THE QUALITY of your dog or bitch and are willing to let judging decide.
I am not trying to talk you IN or OUT of your decision. PLEASE just be certain WHY you want to get involved.
Being a breeder is MORE than just making puppies. A responsible breeder MUST be a steward of the breed.
