What an incredible journey for Czar and owner Michelle Garza [3] of Lisle, IL! The 13-year-old mixed breed finally came home after three years thanks to his microchip. I still can't believe a senior dog survived as long as he did. If you haven't already microchipped your pup, now's the time! And if your dog is microchipped, be sure to update your contact info. With the holidays upon us and company coming in and out on a regular basis, it'd be easy for your dog to make an unexpected escape. A microchip will give you peace of mind, and better yet, improve your dog's chances of being safely reunited with you.
