Having your pet microchipped is a great, inexpensive way to ensure that he or she has permanent identification. A chip the size of a grain of rice containing a serial number is injected just under the skin between the animal’s shoulder blades. The process in simple, and painless – much like a needle prick that humans feel. We scan all animals for a microchip. If an animal has been chipped, we will have information about its human caregiver.

Please note due to COVID-19 our microchip services to the public is temporarily suspended.
