Shack is a 1 - 2 yr old male Collie/Shepherd mix. He has a high energy level, so he will need plenty of daily exercise. He is loose and wiggly when greeting, and comes when called for snuggles and kisses. Shack does pull on a leash, but this can be resolved with obedience training. He is food motivated and knows the command "sit." He mixes well with other dogs in a kennel and is indifferent towards cats in the shelter environment.
