I rescued my Shih Tzu, Jack, from the animal shelter where they had given up on him due to his behavior. He was labeled aggressive and unadoptable. Horribly abused, Jack had lost his eye and trust in humans but, looking into his one good eye, I saw his heart. Jack calmed himself for me and I’m now trying to rehabilitate him. Jack will not be able to wear a collar or harness for a while. With PetLink’s chip, I know that if he gets lost, this fierce little guy will get home to me safely.
