Dog Tired

Riley spent the day with G.  They walked in the woods (off leash) and did many, many errands.  They even went to Petco to buy more dog walk treats and to the vet for a Lyme test and a shot.  And then Riley went to sleep.  He's snoring.  He hasn't even had his dinner yet.

Riley has been tired, lately.  Last night, I asked if he wanted to go out for "last call" and he didn't stir so I checked to see if he was dead or something.  I leaned over and touched his side and he jumped a foot off his dog bed.  He was that sound asleep.  Of course, it didn't take but a nano second to switch gears from sound asleep to racing down the path into the back yard.  There is always the possibility of deer loitering in the back garden late at night.

Why do animals sleep with all four feet touching?  And why are sleeping dogs so darned cute?
