I have been blessed with a puppy “Leo” and as part of his basic puppy care I had a microchip put under his skin when he was being neutered. Painless, universal, worldwide identification, available 24 hours, seven days a week. I choose The Petlink company because a one time fee $42.00, pays for the identification library service for the life of your animal. The other microchip companies typically charge a yearly fee ($35.00) to keep the information on your pet. Many Veterinarians carry the yearly fee Company because this company gives the supplies to the Vet Office for free. The Petlink has a charge to the Vet. for the reader and implants which are refunded to the Vet as they implant the microchips. The website for Petlink has a list of Vet.s by Country and State that have their microchips available. http://www.petlink.net/us/owner/vetList.spring
The link below has a photo of the chips and info on the millions of lost pets who never make it home.
