A microchip is a small capsule that is around the size of a grain of rice. It carries a unique identification number and is made of inert material so it won't be rejected by your pet's body. It has no power source and has a special cap to prevent movement once it has been professionally implanted.

Pet microchips contain no internal power source so will last for an extremely long time. They are designed so that they do not act until acted upon and they are inert so they won't be rejected by a pet's body.

Most pet microchips comprise three basic elements: A silicon chip (integrated circuit); a coil inductor, or a core of ferrite wrapped in copper wire; and a capacitor. The silicon chip contains the pet identification number, plus electronic circuits to relay that information to the scanner. The inductor acts as a radio antenna, ready to receive electrical power from the scanner. The capacitor and inductor act as a tuner, forming an LC circuit. The scanner presents an inductive field that excites the coil and charges the capacitor, which in turn energizes and powers the IC. The IC then transmits the data via the coil to the scanner.

These components are encased in a special bio-compatible glass made from soda lime, or a strong bio-polymer material, and hermetically sealed to prevent any moisture or fluid entering the unit.

The implantation is a quick and painless procedure that should hurt no more than a vaccination. In the case of dogs and cats this would be done just behind their shoulder blades by a qualified implanter using a special pre-packed sterile needle. Your vet or local animal welfare centre will also be able to advise you where to have more exotic pets and fish or horses microchipped, as this a specialist procedure.

After that, there's nothing else to do - your details along with those of your pet will be registered with Petlog's Lost and Found Pet Service automatically by your implanter. If your pet goes missing, most vets, animal charities and local authorities have microchip readers, so when someone hands your pet in, they can read the chip's 15 digit code and contact the Lost & Found Pet Service.

The importance of encouraging and promoting responsible pet ownership through pet microchipping as the preferred method of permanent pet identification has been recognised by all animal concerned organisations. Pet microchipping ensures we can reunite pets with their owners as quickly as possible.

There are numerous organisations that hold pet microchipping courses. These are usually half day courses and once you have completed this you will be supplied with a Petlog PIN. You can then purchase pet microchips directly from a manufacturer and register them with the Petlog Lost and Found Pet service. We would advise that you search online for pet microchipping courses in your area. Once you have completed the course you will be able to microchip dogs, cats and small furries. Other animals may need a professional veterinarian. See the bottom of the page to see a list of manufacturers that are part of the Petlog Lost and Found Pet Service and may provide courses for you.

You can get your pet microchipped by welfare centres, animal wardens, vets, even pet stores or independant implanters. There is no set price for the pet microchipping. Each implanter will charge however much they wish so if you think it's too expensive, look elsewhere.

After your pet is microchipped, the details will be registered with a Lost and Found Pet Service. If the worst happens and your pet goes missing, it is very likely that they will be picked up by the Animal Warden service, or by one of the Rescue organisations. These agencies are equipped with a special scanner which can read the lost pet's unique microchip number and this will enable them to find your details through the Petlog Lost & Found Pet Service which is open and accessible 24 hours a day, 365 days of the year. You will then be contacted directly so they can reunite you with your missing pet. If a stray pet is found out of office hours, it is likely that a local authority will pick it up and hold it overnight. Animal Wardens will have access to the Petlog database and will search for the microchipped pet's details so that they can return your stray pet to you as soon as possible. For these reasons it is very important to keep your details up to date on the microchip database. If they are not accurate it can result in extra fees from a kennels, a longer period of distress for both you and your pet or at worst your pet being re-homed.

This service provides the best opportunity to get your pet reunited with you as soon as possible. Petlog Premium provides:

  • Free amendments for your pet - also available online(excludes Change of Ownership)
  • Lost Pet Alert sent to Vets, Welfares and animal wardens
  • Temporary Address details can be added
  • Second Carer details in case we can't contact you directly.
  • Collar tags

This is all for a one-off fee of £10 per pet (for the lifetime of the pet whilst in your ownership). If you are on Petlog Premium contact Petlog as soon as your pet strays so we can send out the alert for you and make sure that all your details are correct.

The Petlog database holds the information for the majority of UK suppliers. The following suppliers are covered by Petlog:

Follow the links to go to their websites. Petlog is not responsible for any information held on the manufacturers' websites.

The 'expiry' date on a microchips barcode sticker is purely there for the implanters information. They simply have to ensure that they have implanted the microchip before that date. It does not mean that you will need to have your pet microchipped again, or have to pay an extra fee after that date.

The microchip itself is designed to last for longer than the lifetime of your pet.

Firstly, create an online account. Then you can link your pets microchips to your account and amend the details from your personalised page. If you need to change over the ownership of a pet, you will need to send in the paperwork to show you are the new owner. You will need a Petlog confirmation letter, or a re-homing form to get this changed. If you have neither of these please contact Petlog on 0844 463 3999, quoting the microchip number.

You will need the microchip number and Petlog ID to link a pet to your account. IF you do not have these, or are having problems with the website, please contact Petlog on 0844 4633 999.

The address to send the change of ownership request is:

Petlog
4a Alton House
Gatehouse Way
Aylesbury
Bucks HP19 8XU

The initial fee, charged by the implanter is a transaction purely between themselves and the pet owner. The implanter completes the registration form and forwards this to Petlog. All the information is entered onto the database within 5 working days of receipt. Petlog does not charge for this initial registration and we provide the pet owner with a confirmation of registration and a lost/found service open 24/7 all year round, with experienced staff on hand to provide support, assistance and guidance to pet owners and authorised agents.

If you never make any amendments to your record for the rest of your pets life, then you will never incur any charges. To ensure the continuation of our operation and services especially the 24/7 opening hours, we must charge a fee for certain changesso we can maintain and improve our service for you. Currently we are doing this at a special price of £10 - this then covers your pet for the rest of it's life.

Your Petlog ID number can be located on your Petlog confirmation letter, or Petlog Premium certificate. This should be on the top right of the front page if you have a recent document. For older documents it may be located close to the microchip number, or possibly at the bottom of the letter. This number is generated when your pet is registered with the Petlog database and as such this number cannot be located on the Petlog Basic Registration certificate.

The Control of Dogs Order 1992 mandates that any dog in a public place must wear a collar with the name and address of the owner engraved or written on it, or engraved on a tag. Your telephone number is optional (but advisable). For more information on collar tags or to order a brass tag with details engraved, please go to the Pet Identification (Collar Tags) page. We strongly recommend that you do not put your microchip number or Petlog ID number onto any tags. If you wanted to put a reference to the microchip it might be worth putting your postcode, the pets name and our telephone number. From this information we would be able to advise the finder on the best course of action to get your pet safely home.

The '44' at the beginning of a number denotes the International Dialling Code for the United Kingdom, putting this at the beginning of a UK mobile number is for SMS purposes. This is mainly for marking your pet as missing or found via SMS when you are on the Petlog Premium service. If we use this number to contact you we will know to replace the '44' with a '0'.

If you have any questions that are not answered above, please contact us directly on 0844 4633 999, or by email.
