Fish 'n' chips
Let's make this a small article, folks—as small as the rice-sized microchips that get implanted in cats and dogs.
You may agree with this statement: Every pet owner—for their peace of mind and their cat or dog's future safety—needs an ISO-compliant (for maximum readability everywhere) microchip inserted in that cat or dog. Then the pet owner needs to register that microchip in any of a number of national databases and keep the information updated through any moves or changes in ownership.
Microchips can't guarantee a pet will come home, but they sure improve the chances.
There are a slew of microchip companies on the market—911PetChip, AKC Reunite, PetLink, just to name a few—and many of them encourage humane societies, animal shelters and, yes, veterinary practices to offer the service to clients.
People, you can't heal 'em if your clients can't find 'em!
