It's National Pet Identification Week -- the perfect time to make sure you've taken every precaution to be reunited with your pet if he or she becomes lost. The American Society for the Prevention of Cruelty to Animals (ASPCA) recently found that only 33 percent of pet parents admitted to always having ID tags on their dogs and cats.In addition to that crucial step, pet owners should also have their furry friend microchipped. Collars with pet identification are accessible to anyone who finds your lost pet. But, tags can become hard to read, and collars can be broken or removed. Microchipping your pet is a method of permanent identification. Microchips cannot be easily misread, and the permanent identification number is tamperproof. The information about the pet and owner is usually readily retrievable.A microchip is a very tiny transponder that is encoded with a unique identification number. Before insertion, the sterile microchip is scanned in the package to confirm that the identification code of the transponder matches that shown on the label of the bar code on the package.
