I am debating if I should neuter my pup at the vet recommended 5 months old, the breeder recommended 12-18 months old… or if I should stud him out. Both his parents/grandparents and more, especially on his sire’s line, have been health and temperament tested. He is a very good pup; very calm, lovable, and easy to train. If he can produce litters half as good as he is, it would be a benefit for the breed. I just don’t know if there is a market or need for it; seeing all the great pups and dogs on this page. German Shepherds seem to be an excellent breed all around. What do you all think? Looking forward to all expert and non-expert advice. Before I make any definite decision, I will definitely get all testing needed beforehand (hips, elbows, cardiac, DM, etc.), and would require the same of any mate.
