Stan and his pit bull friend Penny Lane met at the Swift Run Dog Park in Ann Arbor in early February and they've been BFFs ever since. They really play well together and know each other's limits. They could tangle for hours on end, and that's just what they did Friday after I got off work and drove to Ypsilanti for a doggy play date at Riverside Park. Stan is totally an alpha male, by the way. He courageously picks on bigger dogs at the park and I overhear this comment a lot: "Man, that's one tough puppy!"
