Duke is a strong young rottweiler. He is incredibly affectionate and chilled out, but loves his balls. That's his prize reward and works best with training. In terms of recall, if there are no rabbits, squirrels or cats - his recall is excellent. It's the chase he loves doing and once in that state of chasing, it can be difficult to snap him out of that state. He loves to do things for you, for example tell him where to dig and he will.
