A veterinarian inserts a HomeAgain microchip beneath the surface of skin between the shoulder blades of a pet similarly to how a shot is administered. The pain experienced is similar to that of a vaccination and does not require anesthesia, according to the HomeAgain website.
A HomeAgain microchip provides identification for pets in the event that they go missing. Once a microchip is implanted, the owner registers the information in a database, and the pet is assigned an identification number. Shelters and veterinary offices are able to scan the microchip to acquire the ID number and find the owner's contact information in the pet-recovery database, as stated by HomeAgain. The microchip utilizes radio-frequency waves to transmit registry information and is not used for finding the GPS location of a pet. Microchips should not be a replacement for collars and tags, according to the Humane Society of the United States.
Microchips are intended to be permanent implants requiring little to no aftercare. Microchips bond to subcutaneous tissue within 24 hours of being injected and should not migrate, according to the HSUS. They are designed not to biodegrade over time, nor need any type of repairs or maintenance, as stated by Petfinder. A change of owner or contact information can be updated through the HomeAgain database registry. An pet owner can have their pet's microchip tested while at a veterinarian's office.
