Understanding Microchips for Cats and Dogs

Friends and Neighbors,

As city dwellers, it’s imperative that we microchip all of our pets - even if they don’t spend much time outside! Life happens and even the most diligent pet parents can experience an accident that leaves their poor pet missing. We’ve answered some microchipping FAQs to help better understand the importance (and ease) of microchipping your pet!

But what if the collar comes off?

To protect pets in this scenario, many owners turn to technology in the form of microchips implanted in their pets. But don't rely on a microchip alone to protect your pet. In the event of accidental separation, identification tags are your pet's first ticket home. Microchips provide an extra level of protection in case your pet loses his collar and tags. Providing your cat or dog with both tags and a microchip can help ensure a happy reunion if the unthinkable happens and your companion gets lost.

What Are Microchips?

Microchips are tiny transponders, about the size of a grain of rice, that use radio frequency waves to transmit information about your pet. They are implanted just under the skin, usually right between the shoulder blades in a minimally invasive procedure, quite similar to a vaccine injection. This can be done during a brief office visit or while they’re getting spayed or neutered.

How They Work:

Each microchip contains a registration number and the phone number of the registry for the particular brand of chip. A handheld scanner reads the radio frequency of the chip and displays this information. The animal shelter or vet clinic that finds your pet can contact the registry to get your name and phone number.

Can a microchip get lost inside my pet?

Your pet's subcutaneous tissue usually bonds to the chip within 24 hours, preventing it from moving, although there's a small chance that the chip could migrate a little off center, it can't actually get lost inside your pet if placed correctly.

How long do microchips last?

Microchips are designed to work for 25 years.

How do I register my pet?

Complete the paperwork that comes with the chip and send it to the registry, or do it online if that option is available.  Some companies charge a one-time registration fee while others charge an annual fee.  You’ll also receive a tag for your pet’s collar with the chip number and registry phone number.

Are there different types of chips?

Yes, and that used to be a problem. Competing microchip companies used different frequencies to send signals to scanners, and until recently there was no universal scanner that could read all the different frequencies. That was a problem if a pet had a microchip that a scanner couldn't detect.

Many microchip companies now produce universal scanners and provide them to animal shelters and animal control agencies at no or very low cost. If your local shelters don’t have scanners, they can contact some of the major manufacturers to ask about getting one.

Are there different registries?

Yes, and that, too, used to be problematic. Different chip companies maintained separate databases. Now, some chip companies will register pets with any brand of chip Also, the American Microchip Advisory Council is working to develop a network of the registry databases to streamline the return of pets to their families.

Can a microchip replace my pet's collar and tags?

Despite advances in universal scanners and registry procedures, microchips aren't foolproof, and you shouldn't rely on them exclusively to protect your pet. Universal scanners can detect a competing company's chip, but they may not be able to read the data and if shelter or vet clinic personnel don’t use the scanner properly, they may fail to detect a chip. A good Samaritan may also fail to recognize a pet as having an owner already, especially when it comes to outdoor cats.

What if I move?

You need to contact the company that registers the chip to update your information; otherwise, the chip will be useless. You may be charged a small fee to process the update.

What do I do if I adopt a pet who's already been microchipped?

If you know what brand of chip your pet has, contact the corresponding registry to update the information. If you don’t know what type of chip your pet has, find a vet or animal shelter that can read it.

We hope you find these tips (and chips) useful! Don’t hesitate to reach out if you have any questions or to schedule an appointment. We’re always here for you and your pets!
