Sleeping dog running away

It's a little funny.
But poor dog, i think it's head might be hurting after that.

Yeah maybe. I'm actually surprised how it managed to run so actively and still to remain sleeping for a while!

The mysteries of animals.

Probably. My cat does the same while sleeping sometimes. Though not so heavy as this doggie.

Maybe it's running after someone or after some food.

...or running away from someone...

Maybe but for now it will remain a mystery.

Oh my gosh! Never thought an animal could get so into it!
