General Questions

 What is the microchip?

The microchip is a tiny computer chip which has an identification number programmed into it. The chip is encased in a smooth, strong biocompatible glass, and is small enough to fit into a hypodermic needle. Once an animal is injected with the chip, he can be identified throughout his life by this one-of-a-kind number.
How does the microchip work?
The microchip is generally injected deeply under the skin. It sits safely there, totally inert. A special scanner is used to send a radio signal through the skin of the animal to read the chip. The animal feels nothing as the scanner is passed over him. The microchip sends it’s number back to the scanner. It appears in the viewing window.
How long does the microchip last?
The microchip has no power supply, battery, or moving parts. It is designed with an operating life of over 25 years and is guaranteed for the life of the animal. Once injected, the microchip is anchored in place as a thin layer of connective tissue forms around it. The chip requires no care. It does not pass through or out of the body.
How does the scanner work?
The scanner sends a safe radio wave signal to the microchip. When the chip receives this signal, it sends data (the microchip number) back to the scanner to be displayed in a viewing window. Scanners emit helpful audible beeps, display descriptions of actions in progress, and have a low battery message. Small handheld scanners are held close to the implant site while scanning. They have a reading range of about 3 inches. Larger, more powerful scanners can be used for various commercial and research applications. Read ranges vary from 6 to 20 inches depending upon specifications.
Are microchips and scanners "Universal"?
ISO FDXB is the most cross-compatible microchip system on the market. They are approved by FECAVA, The Federation of European Companion Animal Veterinary Associations and are required as part of UK Pet Passport Scheme for travel or export abroad.
My pet already has a microchip.   How can I get him registered on the National database?  How can I change his registration?
Please contact Petlog directly on 01296390602.  They will answer all of your questions and/or send you an application.
Who can  microchip animals belonging to others?
A veterinarian or other person certified capable of performing the proceedure. There are two reasons for this. The microchips are registered upon purchase to the buyer, and secondly, animal law states require that you be a veterinarian or other suitably qualified to do any "invasive" procedure to animals other than your own.
Does the procedure hurt the animal?
Although the microchip needle is larger than a typical vaccine needle, the general rule is this…your animals will react the SAME way to this shot as they do to any other. No better, no worse. Animals do not over react to it. Their physical performance is not impaired and there is no scarring. You are not injecting any substance that can burn or irritate; the chip is completely biocompatible and non-offensive.
Does the animal have to be sedated for the injection?
No! Injecting the microchip is just like any other injection or vaccination. Anesthesia is not required or recommended.
Could my animal be allergic to the chip?
The microchip is inert, smooth and biocompatible. There is virtually no chance of the body developing an allergy or trying to reject the microchip after being properly injected.
Can the microchip move around once inside the body of the animal?
When properly implanted, a small layer of connective tissue forms around the microchip, preventing movement or migration of the chip.  Instructions and injection sites will vary depending upon the specie.  As with any brand of chip, microchips will not migrate if instructions are followed and implantation is correct.
What is the best age to inject the microchip?
Minimal age varies somewhat depending upon the specie.
What do you mean by the chips are "registered" upon purchase?
Microchips purchased are traceable back to the implanter. They will always be traceable back to their facility of origin, unless the registration of the chip is changed.
What if  buyers/clients want the chip registered to them?
If buyers want the chip’s registration changed, there is one way to do this. The animal is registered under the breeder name (as owner) and the new home details are listed as "keepers"  with complete detailed information about both animal owner and keeper. In this way, if a shelter picks up the animal, the breeder/owner AND keeper will be contacted directly.
If the animal shelter picks up one of my animals, how do they know to call Petlog?
Animal shelters and animal control officers have been educated and informed about microchip identification and how it works.  The majority have universal scanners on hand and routinely scan lost pets.  Once a microchip is located in an animal, the appropriate steps are taken.  If the animal is registered with Petlog Recovery  System, the shelter will be given the owner's name.  If the animal is not registered, they will be given the name of the veterinarian or the implanter who injected the microchip.

Where is the injection site in dogs and cats?

Dogs and cats are injected between the shoulder blades with a deep subcutaneous (under the skin) delivery of the chip.
How early can puppies and kittens be injected with the chip?
Most breeders identify their breeding between the ages of five and eight weeks of age. Of course, the injection can also be done at any time after that.
Will the implanted microchip move or migrate?
Microchips are sealed with a special smooth coating.  This coating, once in contact with body fluids and subcutaneous tissue, helps the microchip stay where you put it.
In the show ring, can the microchip be felt by the judge’s hands?
No. When the chip is properly implanted deeply under the skin, no one will be able to locate the chip by touch, even in tiny breeds.
What are the KC regulations and rules regarding the use of microchips?
The use of microchips satisfies the KC’s policy for record keeping and identification.
I have toy breeds/kittens. They are so tiny. Can I use the chip?
Absolutely. You can have your puppies/kittens ID'das early as six weeks. Remember, the same sized microchip and needle are used in animals even smaller than yours, including mice, baby birds, and even fish!
