Instructions
Contact your equine veterinarian to see if he does microchipping. If he does not, search for a vet who does.
Have the veterinarian perform a scan on the foal if you are not its first owner and you are not sure if it already has a microchip.
Move the mare and foal away from other horses, and bring them to where they will be easily accessible to the veterinarian when it is time to insert the microchip.
Keep an eye on the mare while you and/or the veterinarian are preparing to insert the microchip in the foal. She may get agitated and try to protect the baby if she believes you are harming it. Tie her up if she gets aggressive.
Be alert while the veterinarian is injecting the microchip. The foal may react unpredictably to the sensation and you may have to help comfort it.
Ask the veterinarian about registration procedures for the microchip he has implanted, and then fill out any necessary paperwork or online applications.
How to Microchip a Foal
Horses can be very expensive to buy. One way to protect a horse that you love and prize against theft or loss is to have a veterinarian insert a microchip in the horse's neck. The microchip will allow you to track the horse's location. Some equine breed registries in the United States highly recommend microchipping, while in some countries, it has become a requirement. A horse can be microchipped at any time in its life, but if you have a prized foal, you may want to do it while it's still young. Microchipping by a veterinarian costs approximately $50.
