Sometimes sleepiness gets the best of us. You know, that feeling when you just cannot keep your eyes open. This wiped-out pup totally gets it. The little canine makes a valiant effort to stay awake in this video. We're not even sure if drinking the water is the goal here, since the puppy's front paws are in the water throughout the clip.
But in the end, exhaustion wins out. Research says being so tired you can't keep your eyes open, means we're actually experiencing "microsleep" -- a momentary and involuntary space of temporary unconsciousness which can last anywhere from a fraction of a second up to 10 seconds, and typically ends with a sudden head jolt. Adorable during puppy dinnertime, but very dangerous for humans driving cars or operating machinery.
Be smarter than this little guy -- just call it when it's time to go to sleep.
