Clyde's dad says: Though Clyde has crossed the puppy threshold, he still has enormous amounts of energy. It's a bottomless pit of energy really. To let him burn off some energy, we try to take him on very long walks and to the dog park, where he prefers to run with the big dogs. During his walks, passersby always want to say "hello," which truly delights him. He's sort of regarded as a local celebrity. He adores attention, and his moments of calm are usually while he's on a warm lap or being held and petted. He also does the head tilt thing, usually when he hears the rustle of a bag of treats.
