MICROCHIPPING COULD SAVE YOUR PET'S LIFE
A microchip ID is a small transmitter about the size of a grain of rice. When a scanner passes over it, a signal is emitted indicating the unique identification number of the chip. This tiny but sturdy little implant can reunite you with a lost pet, can serve as proof of ownership in a dispute, or can even mean the difference between euthanasia and medical care in an emergency. In many communities, it is not legal to own an unmicrochipped dog and in many communities shelters automatically microchip any pet that is released through its doors for adoption.
Microchipping has been around for over thirty years yet there is still some resistance to chipping in the pet-owning public. Questions commonly arise about about how the chip is inserted, what information is contained on the chip, the difference between a registered chip and an unregistered one, what to do if a chipped pet is lost, and more. There are many misconceptions about chipping. For example:
This FAQ hopes to clear up any confusion.
MICROCHIP IMPLANTATION: BASICALLY A SHOT WITH A BIG NEEDLE
The microchip ID is small enough to pass through the bore of a fairly large needle made for this purpose. Microchips are generally shipped in an individually packaged syringe made for chip implantation. Implantation is basically a shot and, if you like, it can be done in the examination room while you watch. The needle is fairly large so sometimes there is a yipe but, more often then not, the reaction is minimal. Chips can be implanted in newborn animals to assist in telling them apart. Some people like to wait until the pet is being spayed or neutered so as to be anesthetized for the rather large needle but waiting runs the risk of the pet escaping unidentified so it is a good idea to implant the chip as soon as possible.
A common misconception is that the chip implantation requires surgery.
CAN A MICROCHIP BE USED TO LOCATE A LOST PET?
No. A microchip is not a location device. At the present time, GPS collars are available but their use is limited by the fact that a collar can be removed or can come off.
A microchip is an identification device, not a locator.
WHAT HAPPENS IF THE CHIP DOES NOT GET REGISTERED?
It is vitally important that you register your chip. Simply having a chip will not bring your pet home to you. Many rescue groups, pet stores, and shelters will implant chips, let you know your new pet is chipped but leave the registration (which usually requires a fee) up to you. Many animal hospitals will chip your pet and then give you the mail-in registration form to complete the process at home. Be very clear about this point when you get a new pet that comes with a chip. It is easy for the registration forms to get mixed up in receipts, vaccination records and other paperwork.
If a pet with an unregistered chip is found it may still be possible to trace the owner. The manufacturer of the chip is usually identifiable from the chip number. The major microchip manufacturers keep records of the facilities to which they have sold their chips. In this way, the facility where the chip was implanted can be identified. If that facility has records, the owner may be identified and contacted. This process assumes the manufacturer keeps records (smaller companies do not), that the facility where the chip was implanted keeps records, and that the owner's phone number is the same. If there are no records, this all leads to a dead end. It is very important to keep your registration current.
If your chip is not registered and someone finds your pet and wishes to keep him,
Often a chip is implanted and the registration forms are given to you to fill out on your own.
MUST THE CHIP’S REGISTRATION BE RENEWED ANNUALLY?
For the major brands of microchips, the answer is no. Once the chip is registered, that registration is indefinite. This is a good thing in that the chip never becomes unregistered after it has been registered. The problem is that people move or the pet changes ownership and the chip information is never updated. Some chip registries have developed deluxe programs that do require annual renewal largely as a means to remind you to keep your information current.
WHAT SHOULD BE DONE FOR A PET THAT WAS ADOPTED WITH A CHIP REGISTERED TO A PRIOR OWNER?
Each chip company seems to have their own policy for this situation. Some will require a written note from the original owner allowing registration change. Some companies attempt to contact the original owner for a defined amount of time and if the owner is not reached then the chip may be re-registered. Contact the chip company that issued the chip for instructions in this situation.
IS LICENSING THE PET WITH THE CITY GOING TO AUTOMATICALLY REGISTER THE CHIP?
Don't count on it. When a dog is adopted from a city shelter, it is common for the dog to be issued a license and for a microchip to be implanted and registered but this depends on the city. The dog license registration will include information about the dog's rabies vaccination, ownership and microchip number if there is one but that is not the same thing as registering the chip. If the pet is found and brought to the shelter, the chip will identify him in the shelter's records but if the pet is found and brought any where else, identifying the owner will depend on whether or not the chip is properly registered.
If the shelter does not register the chip in a chip registry then it will be up to you to get the chip registered. Be clear on whether you need to do this and read your adoption paper work carefully for special instructions. Many people receive a small pile of papers with the adoption and simply put them all in a drawer without looking through them and may miss the chip registration form or other important directions.
HOW MANY REGISTRIES ARE THERE AND DOES IT MATTER WHICH ONE TO USE?
There are many chip registries and a chip can be registered in any of them. The good news is that most chip distributors have their own registries and it is easy to find a chip’s most likely registry based on its number. For example, AVID chips are generally in the AVID database, HomeAgain chips are generally in the HomeAgain database etc.
WHAT SHOULD I DO IF MY PET IS LOST?
Notify the chip company so that the chip number will be flagged as belonging to a "lost pet." If the company has a system beyond their chip registry, your pet's photo (assuming you have uploaded one) will be circulated to local animal hospitals and shelters. Be sure the chip company has your correct telephone number and contact information should your pet be found. Be sure to check the local animal shelter and inquire as to how to proceed there. Posters around the neighborhood also help. Hopefully your pet is wearing some sort of identification as well (such as the tag that came with the chip) so that you can be contacted by the finder directly.
WHAT TO DO IF A PET IS FOUND?
Running the pet to a local animal hospital or shelter will allow for rapid scanning for the presence of a microchip. If a chip is discovered and it is registered, it should not be difficult to find the owner. It is amazing how long some animals are lost before someone thinks to scan them. If you find a stray dog or cat, be sure to have it scanned sooner rather than later in case someone is out there searching. If there is no chip or identification tag, check the lost ads in the local newspaper listings. If there is no match up, you may be legally compelled to bring the animal to the local animal shelter as this will be where the original owner is likely to look.
