My Baby Girl is a big white American Bulldog. Twice in four days she got under the fence, she even broke it down. We hunted for her all during the night and thought that she had probably been killed. But she ran down to the Safeway store and was taken to the pound. They read the little chip in her neck and now she’s home and can’t get out no more. My little dog was enticing her but I’ve put double screws in the fence to keep her in. Thank you so much! I am so glad I went with PetLink.
