Puppies are born without fully developed neurological systems. The most obvious indication of this is that both their eyes and ears are closed at birth. Another interesting trait of new born puppies is called "Activated Sleep." It is thought to be the process of the young brain building neural connections as the young puppy sleeps. It looks funny for these young puppies twitch and jerk, mouth and wiggle. At times they seems to be running - and it does make you wonder if they are dreaming of adventures to come!
