He is incredibly intelligent. He legit does physics experiment with his ball, placing it on or in objects around the house and observes the results with his head cooked to one side. He loves his family more then anything, with food being a close second. Wonderful with kids and has even helped one friend of my son become much less afraid of dogs. Super stubborn, athletic and an escape artist rivaling Houdini, he keeps us on our toes, but he is so darn lovable its impossible to not instantly forgive any transgression involving pilfered snacks. Digby also talks, he has several replies and retorts, and says "uh-huh" when I thank him for moving over on the couch.
