Hopefully no vet would agree to euthanize a perfectly healthy dog. Please never get any dogs again if you think that killing a healthy, non-terminally sick dog is somehow an option for anyone with a basic sense of morals. Return him to the people you got him from or, if you have a Facebook account, join some of the local pet re-homing groups in the area and find someone who wants him. Make sure to charge a re-homing fee of at least $50 in order to avoid giving him to someone who will abuse him or put him into a dog-fighting ring. Although since you seem to have no morals yourself, so I think you'll probably just give him to the first sociopath that says they'll take him. You make me sick, frankly. I can't even continue writing this comment to your post. Please kill yourself so that no one else has to be subjected to your sick sociopathy.
