The opening for your hand is behind the front legs. Your whole hand fits in the mouth to pant and slurp. Or, you can move the lower jaw and front legs at the same time. If you put your index and middle fingers in the lower jaw, your thumb and pinkie fingers will reach the front leg openings. Use your other arm as a support to rest the hound, then with your free hand you can wag the tail and the illusion is complete!
