Duke is a big, lovable guy! This chocolate lab / Chesapeake Bay retriever mix is just what you would expect -- an active, smart and playful boy. He gets along well with most dogs, but we aren't sure how he would do with cats. Because he is so big and strong, he would do best in a home with no small children. Duke is about 4 years old and has completed some basic obedience training. If you are looking for a big, active boy, Duke may be your guy!
