For an average one-time cost of $45 at the majority of local veterinary practices, a microchip can be injected into the dog. It is a sad fact that hundreds of dogs go missing every year and are found, rather bedraggled but perfectly healthy, handed into the local animal shelter, which then searches desperately for the animal’s owner to no avail. If nothing else, please put a Tag on your baby. at Gundogsupply.com they have these nice poly-coated nylon hunting dog collars with brass engraved tags for like $10. The best part, they stay clean. You can also buy from eBay.
