After playing ball for 1/2 hour he decided to entertain himself. He is passed out on the couch right now. A tired happy dog is a good dog!
That so reminds me of Lucy. She digs like that all the time. Usually comes up with a stick, piece of ice thens runs around the yard throwing it up in the air and chasing it till it disappears. She's always digging up and eating ice. I've had other dogs that if they ate something cold like that would barf almost immediately, but doesn't seem to bother her.
