This month, one of our favorite posts on the Grouchy Puppy Facebook wall had to be Mosley the greyhound having the best time playing in the snow, while wearing his Batman pajamas. Yep, Batman pjs.

It got such a response from viewers that Mosley's guardians commented, writing:

"Always be yourself, unless you can be Batman. Then always be Batman! - Mosley & family."

Sounds like good advice for man and dog in my book.

Watch Mosley the greyhound race the moon for yourself then let us know in the comments if you've ever seen a happier dog, in the snow or wearing pajamas.
