Our granddawg Shadow, now at the advanced age of 12, REALLY knows how to sleep (as most doxies do). Pictured above, he's lying on the couch in the evening, enjoying TV like many men do, LOL.
He's still pretty spry for his age, however (which happens to be 84 in dog years). Just let Duke grab one of Shadow's toys, and watch how fast ol' Shadow can move! His philosophy is "my toys are mine, your toys are mine, ALL TOYS ARE MINE." Duke, who is larger and younger, always acquiesces to Shadow. Such respect from the young whippersnapper!
Here's another pic of a younger Shadow sleeping in one of his favorite spots (the bed):
In fact, from my experience with doxies, I believe they can sleep just about anywhere, anytime, for any length of time! You gotta love 'em.
