Hank is the biggest dog in the club. Dottie is the smallest. I got a photo of both of them in the blind and superimposed them on top of each other. As you can see, the man only shows up once, and that is because I made sure he was the same size in both photos. Therefore, the size on both these dogs are correct. I think our helper prefers to work Dottie because her small size doesn't leave him feeling sore and tired!
