I know some of the dogs that have been used for breeding for petstore dogs. Do you have the names of the sire and dam of your dog and the breeder's name, city and state? Would they happen to go back to Tankersley's, WL's, and/or Reedgate's kennels?
I did a reverse pedigree on Omar's They Call Me Junior and one can follow it to the Misty Mountain kennel. Some of their Bs went to rescue and the remainder went to other breeders, Tankersley, Reed, Choate-all commercial breeders. I saw some of these dogs at the dog auctions.
