I don't want to go home!

In the dog world this is called a "Sit down Strike" or "The stop and drop phenomenon" But before you scold your dog check to see how your dog is feeling. Make sure your dog has no sprains or pulled muscles. Also check your dogs paws. Look for ice, cracked pads of feet or foreign object wedged between paws.

The laying down behavior could also be that your dog is overwhelmed, scared and shutting down.

Or your dog is just being silly and having fun! Like Charlie is :)
