According to the American Humane Society, just 15% of dogs in shelters ever find their way home again. Thankfully, these loved pooches had identification, enabling shelter personnel to contact and return them to their owners. With such discouraging statistics, it becomes clear how important it is to tag or identify your new puppy.

Even if your dog doesn't go outside much or is always in your company, you must identify him or her. Windows and doors can be left open, offering your pup a too-tempting escape to the outside world. What should you do to keep your pup safe at home?

There are several ways to ID your pet to prevent against loss or theft. Ideally, implement at least two methods to ensure a safe return should your dog go missing.

Tattoos and microchips provide permanent ways to identify your dog. Shelters, veterinarians, and research laboratories know to look for these keys when animals are brought to their facilities.
