Full speed ahead

Caught Scrubs digging in the yard last night. Called him in. Sent him straight to his kennel. He was incredibly hyper so he went running at his kennel at nearly full speed. Only problem was, it was dark in the kitchen and laundry room. He couldn't see well. He didn't know that his kennel door was closed. He ran into that thing at nearly full speed and bounced back nearly ten feet. He truly looked like he was seeing stars. Serves him right. What kind of dog digs anyways?!
