Oggy just about knocked me out one time. He was whining beside the bed, (his usuall help me i'm a poor puppy routine), as I bent down to pick him up, he jumped up and knocked me flying. I had a big lump over my eye and it was almost closed. I hadn't been hit that hard for a good twenty years. I think he was sorry though. I ended up sitting on the couch with ice over the eye and Oggy's head in my lap.
