A lost pet is a frightening situation with often devastating consequences. This is why the team at Mount Laurel Animal Hospital considers HomeAgain microchip lost pet IDs a fundamental way to protect your pet and an important part of responsible pet ownership. Each microchip registers the animal with a unique identification number, which is filed in a database with your contact information. The contact information can be updated at any time, and it is important to remember to do so whenever your information changes. If your pet is lost, the microchip can be scanned by animal control officers, at shelters and at veterinary hospitals in the U.S. and in many foreign countries.
