Captain Jack (aka Nugget) is a little bundle of energy.  Like most puppies, he's very curious and has two modes, warp speed and sleeping, but in Cap'n Jack's case, he's usually at warp factor 11.

He is the last unadopted puppy of a litter of four; and his mom looks like maybe a 25-30 pound Manchester Terrier (but that's large for that breed).  However, Jack's energy level clearly marks him as some sort of terrier.

For the last week, rather than leave him alone, he's being fostered with a litter of 7 lab mix puppies, not quite as old as he is but larger in the attempt to help him learn some more social skills.
