As a buyer, make sure you are getting what you paid for. Don't expect a pet breeder to know what's really show quality. Just reading the standard isn't enough, it takes years of experience by going to shows and seeing first hand many good examples of the breed. A reputable breeder also offers a contract against genetic faults and doesn't evaluate dogs until 4 - 6 months of age, which then you will know more exactly about the dog's breeding or show potential. If you breed a dog that turns out a pet quality, you only continue what is considered a fault, either by standard or health, which on a large scale would eventually lead to the breed's extinction.
Mother nature can be hard on poor genetic examples of animals.
I pity the number of Shar-pei owners that have to deal with major health problems on a daily basis. As a potential breeder, it's your choice whether to help the breed or hinder it. If you are truly interested in breeding, I recommend waiting until you can afford buying a dog that's worth breeding. We shouldn't make pet dogs on purpose, but by eliminating them from a better breeding program. All my dogs are pet companions first, whether for show or breeding, it's a matter of quality for the welfare of the breed.
