Barrett is a 7-9 month old pit bull mix. He is loose and wiggly. He comes when called and will stay next to his person. Tail is not tucked but will be near his back legs. Barrett is mellow most of the time but will have bursts of energy. (medium) He pulls on a leash but with some basic obedience training, this could easily be resolved. He knows the "sit" command. Barrett is not a fan of cats in a shelter atmosphere. Dogs are generally tested with dogs of their own size; and dog meets with the resident dogs are always encouraged.
