A dog can't be consider pure breed(pedigree) even if it doesn't have a cert. Many people avoid the hassle of registering their pups to MKA.

On the other hand, without a cert, there is no prove that pups are pure breed. The cert will show the dog's family tree as well as the award(if any) and origin.

A responsible dog owner will not simply breed dogs and not register them with MKA~! Nor will they mate with dogs with no cert....
