What is a microchip for my pet?
Microchips are a way to keep your pet's identification on him or her permanently. A microchip is about the size of a grain of rice, and it is injected underneath the skin using a slightly larger needle than you see when your pet receives a vaccination.
How does microchipping work?
If your pet is lost and taken to a veterinarian or an animal shelter, a scanner will read the information stored in the microchip. Next, the person will go online and search for the contact information associated with your pet's ID number.
This is why it is critically important to register your information on the website after your pet is microchipped. Always remember to update changes of address and phone number in the system when necessary.
The HomeAgain website briefly explains the process, and there are videos which summarize this information and show pets being microchipped.
