Every Vet should scan, if they don't have the equipment, they should get it.
Last time I had Princess at our Vet, they had a new girl there who didn't know Princess. She scanned her, and I thought it was great. They guy who always takes Princess back came out laughing because she scanned her. He said everybody knows Princess. This my be true, but she didn't, and she was told all unknown furbabies go to the back to be scanned.
With the amount they charge for their service, this is a service every Vet Office should have. Shelters depend on donations to keep them running, and they all have scanners. Why not every Vet too?
