First clue, if a dog yawns for no good reason, it’s probably time for them to be put down for a nap. They are far more willing, the older they get, than you might think!

Don’t call it laziness! These dogs were genuinely exhausted!

What we think is even funnier than their evident sleepiness is how some, awakened with start, look around wide-eyed as if wondering what in the world just happened!

We are always an advocate of “If your pooch looks like he’s ready to fall it’s time to escort him over to his dog bed.” for a nap. And some of the poor dogs above look like they needed some sleep an hour before this realization! Night-night!
