dog ownership certificate

I keep my dog's ownership certificate in a plastic sleeve in the filing cabinet with the vet records and rabies tag receipts. It's just a piece of paper from the breeder with her microchip number and my name as owner, but it came in handy when I needed to prove she was mine after she slipped her collar at the park last summer.
