Duke is a great size German Shepherd mix with a wonderful disposition. He's friendly and energetic when you meet him, but settles down nicely on walks. He doesn't react passing dogs, and generally just likes to be out having fun and seeing what's going on. Duke would make a great dog for an active family. He would probably also love a yard with a little room to run. He seems smart and engaged and knows some basic commands. He also seems super housetrained.
