I personally would not breed him for all the reasons mentioned above but have you even considered whether or not he'd even be RIGHT for breeding? Is he a good representation of the standard? Is he AKC registered? Have you had all the health testing done on him to make sure he is free of congenital defects and hereditary conditions? How is his temperament?
Also, is this puppy going to be bred with a member of it's immediate family? In breeding is something that should only be done by experienced breeders who know their lines inside and out.
There are many things that should be taken into consideration before you decide to breed. Many of which are costly and time consuming. Are you willing to put forth the effort to ensure you are bettering the breed instead of harming it?
Sorry if this is lengthy - you asked.
