Q: What is a microchip?
A: A microchip is a small, electronic chip enclosed in a glass cylinder that is about the same size as a grain of rice. The microchip itself does not have a battery—it is activated by a scanner that is passed over the area, and the radiowaves put out by the scanner activate the chip. The chip transmits the identification number to the scanner, which displays the number on the screen. The microchip itself is also called a transponder.
Q: How is a microchip implanted into an animal? Is it painful? Does it require surgery or anesthesia?
A: It is injected under the skin using a hypodermic needle. It is no more painful than a typical injection, although the needle is slightly larger than those used for injection. No surgery or anesthesia is required—a microchip can be implanted during a routine veterinary office visit. If your pet is already under anesthesia for a procedure, such as neutering or spaying, the microchip can often be implanted while they're still under anesthesia.
Q: What kind of information is contained in the microchip? Is there a tracking device in it? Will it store my pet's medical information?
A: The microchips presently used in pets only contain identification numbers. No, the microchip is not a GPS device and cannot track your animal if it gets lost. Although the present technology microchip itself does not contain your pet's medical information, some microchip registration databases will allow you to store that information in the database for quick reference.
Q: Why should I have my animals microchipped?
A: The best reason to have your animals microchipped is the improved chance that you'll get your animal back if it becomes lost or stolen.
