The American Kennel Club, (AKC), is nothing more than a breeding registry, to assure you of your pup's bloodlines. They offer nothing in the way of confirming that your pup is of *good* stock, merely that it is a purebred.
What you need to do is a Google search on the breed, and find out what genetic disorders they are prone to.
There are health certifications that can be done on the parents to reduce the chances of your pup winding up with some of the nasty genetic flaws, such as hip dysplasia, blindness, bad elbows, etc. Many of these disorders develop after a few years, so just having the pup vet checked is insufficient.
OFA certificates are issued after the sire and dam's hips are X rayed after the age of 2. These X rays are evaluated by veterinary orthopedists, and a rating is given, i.e., Poor, Fair, Good, Excellent.
Find out what your breed is vulnerable to, and go from there.
I recommend you DO NOT buy from a pet store, a puppy mill, or most "backyard breeders".
Their stock is usually without health certificates, and it can cost you a fortune later when your darling dog develops lameness or blindness.
*Some* folks are "hobby breeders", and although done on a small scale in their yards, they will have the correct health clearances on their stock. These folks are generally fine.
Hope this helps.
