Avoid the heartbreak of losing your pet. Westlake Village Animal Hospital provides Home Again Microchip technology, an inexpensive procedure which can be done any time in our office. With Home Again Microchip, your pet can't leave home without his identification. The microchip is injected under the skin with a hypodermic needle similar to a vaccination. If your lost pet is found by a participating shelter, they'll check him for a microchip with a special scanner and contact your information on file.
