Duke was the biggest of the litter from the breeder that we got him from. He is up to date on all shots and is in excellent physical shape. He is very athletic and has a large solid frame. Any further questions, feel free to ask. He is 50% Euro, 50% american - Full Great Dane and of blue color. Oh, also very competitive (even with himself) when it comes to playing with his toys and is very strong compared to my 200 pound 100% american great dane who is 4 years old if that says anything
