Pedigree Certificate is a certificate of pedigree issued by CKU and recognized by the FCI of the World Dog Federation. A \"household registration\" similar to a human society, proving that the dog and the dog's parents and grandparents are of the same breed and that the pedigree is clearly identifiable.
Pedigree certificate is not a single piece of paper. A chip is injected under the left side of the neck of a dog with a pedigree certificate. This chip has a unique chip number, and the chip number is consistent with the chip number recorded on the pedigree certificate.
