I worked at a veterinary clinic where the microchip, both dogs and cats was a popular service. The clinic was located in San Francisco's Pacific Heights, a very affluent area. The clientele were wealthy, educated people with the time and inclination to provide the best for their pets. And on those rare occasions when Fifi managed to stray out of the mansion and some good Samaritan brought her by the clinic, the first thing we did was run a scanner over between Fifi' shoulder blades. We'd detect the ID number, contact the database only to find out that the owner hadn't registered their personal information. FYI, The following database will handle most microchips in the United States...http://registermicrochip.com/ <http://registermicrochip.com/> . but you actually have to register the chip.
Sometimes, the owner would come in on their own soon enough to claim their dog. Sometimes, we'd turn the dog over to Animal Care and Control. This anecdote serves to illustrate several points, not the least of which is that even educated people do some extremely stupid things. You need to REGISTER the chip. Always. Period. <http://>
