Awwww....
Congratulations! That's a precious face! Who'd have thought that inside that little head is the most awesome perpetual motion machine! A friend of ours used to have an Australian Cattle Dog, a sweet soul, and our friend used to sit in his backyard and throw a ball for the dog while he was working on his laptop. Over and over and over again, for hours. They both had a purpose, and they were both very happy.
