Dog and cat micro-chipping is a simple procedure. A doctor or technician simply injects the microchip, about the size of a small grain of rice, beneath the surface of your pets skin between the shoulder blades with a hypodermic needle. The process is similar to a typical shot, takes only a few seconds and your pet will not react any more than he would to a vaccination. No anesthetic is required.
It is not a GPS for your pet, but it does act as a permanent identification method. All pets that are picked up by animal control are scanned to check for microchip identification. It is also standard protocol at all veterinary clinics to scan any stray pet that is brought in. When a pet is scanned and a microchip is present the shelter or clinic will call the company identified by the specific brand of microchip and give the unique ID number assigned to that chip. If the owners have registered that pet with the microchip company, their contact information will then be given to the shelter, animal control facility or veterinary hospital that has found the pet allowing them to promptly contact the owner.
It is VERY important to register your pet once you have the microchip implanted to insure that they are promptly returned to you if they ever get lost. If you have a pet that was microchipped prior to you adopting it or you have since moved and need to make sure the registration information is correctly updated you are welcome to bring that animal in to be scanned so you can be given their unique ID number and a phone number to contact the microchip company responsible for that pets registration.
