More: Xander was a rescue from the Texas/Mexico boarder. I'm a dog trainer and he was supposed to be his foster but I fell in love with him the minute I saw him. He was Heartworm positive but did well with his treatment. Now his job is to help me with the dogs that I train. Xander also tracks people & pets and can run over 30 miles per hour! He is my constant companion and a perfect partner.
