I just looked at PetLink and if you have a different brand of microchip it appears you pay $20 to register it with no annual renewal fees. Home Again is also $20 to register and they try to suck you into paying annual membership fees but they aren’t really necessary. See the FAQs here:
[I]If pet owners decide not to renew their annual membership, will their pets’ microchip ID codes and information still remain in the HomeAgain database?
Once entered in the HomeAgain database, microchips are registered for life, whether or not pet owners renew their annual memberships, and contact information may be updated online anytime free of charge by logging into HomeAgain.com. However, if a non-member’s pet is lost, they are not eligible for the value-added benefits included with the annual HomeAgain membership, such as proactive outreach to local PetRescuer volunteers, medical insurance for lost pets, travel assistance for found pets, the 24/7 medical hotline, etc.[/I]
My dogs are registered with Home Again and I used to pay them annually until I realized I didn’t have to. I would probably use that for my horse as well since I already have the account and the company is pretty well-known.
My question (and yours maybe) is why there are so many different companies that offer this same service and which are the best, most widely used, etc. Does anyone know?
ETA to Dynamite: I did see that advisory when I looked into it. I wish my vet had read it before he implanted the chip.
