I've looked at that website but still don't understand the reason behind doing this test. It doesn't check for genetic defects just parentage. It seems it undeniably verifies parentage, but isn't that what the AKC registration does? There must be something I'm missing.
It is to prove parentage… as you could put any name of any dog on a set of papers and sent them it.... which in cases of Puppy Millers and some BYB's that is was was being done..... so the parents were NOT the parents of a given puppy. If you read the minutes each month on the AKC site (Secretary's page) you can see how many litter registrations were reversed "due" to DNA parentage.
