Frequently Asked Questions

How is a microchip implanted into my pet? Does it hurt?

Microchips are injected into the fatty area between the shoulders of your pet. This area is commonly referred to as the “scruff.”

A hypodermic needle, similar to one used for a vaccination, is used to implant the microchip. No surgery or anesthesia is required, a microchip can even be implanted during a routine visit to the vet.

Does the microchip contain information on me or my pet? Does it act like a GPS device that can track my pet's movements?

The microchips ACS uses only “contain” the identification number for your pet. They can’t act as a GPS tracking device to locate your pet if they get lost, but there are some companies out there that make GPS tags for pets.

Some microchip companies will provide online tools to keep track of your pet’s medical information and vaccination schedule.

Are there any risks associated with microchips?

The benefits of microchipping animals definitely outweigh the risks, but no system is ever foolproof. The risk of an animal shelter or veterinary clinic not being able to detect a microchip is very low, but it is a risk. That’s one of the reasons why Animal Care Services uses universal scanners and has a number of “chip checks” throughout a pet’s stay at the shelter. It’s also why a tag containing the pet's microchip number is required to be worn by the pet.

Ensuring your pet remains on your property and your fences and gates are in good repair will also go a long way towards making sure your pets remain safe at home with you!

If you are concerned about your pet having a negative reaction to microchipping or you have questions about microchips in general, check with your pet’s veterinarian.
