My wife Elida was about to go for a jog. She checked on our dog Choco and he was good. When she came back a good portion of the gate was gnawed off and Choco was gone. She looked frantically around the neighborhood and soon we got a call from the Animal Hospital. Choco had got as far as the next block and a lady that used to work at the vet clinic had him scanned and contacted us. The microchip identified Choco, we picked him up and he was fine. We are very happy with PetLink.
