He's half hound. Hounds chase game. He was just doing what he's bred to do. He just got lucky and caught the deer, 99.99% of the time they can't do that, however, every hound that trails prey intends to catch the prey, otherwise they wouldn't be chasing it. Around here Clod would probably be pretty sought after by the dog hunters. I don't see a need to do anything to him other than keep him tied up or within his fenced yard. Suggesting that he should be shot is perhaps the most stupid thing I've ever heard. What next, shoot cows for mooing?
