I'm Preston, a black-and-white, 9-month-old neutered male pitbull mix weighing about 39 pounds. I like to explore, go for walks, play with my pals, earn treats and spend time with gentle kids who show me love. I was left at the shelter with no note on Dec. 8. I can be a shy boy who needs some tender loving care. I do best when I can be with other dogs.
