Duncan von Dorsten is the cutest 7-8 month old Heinz 57 mix.  Duncan is happy when his kennel is approached, as he can tell an outing is in the air. On leash, Duncan is joyous and playful. He does very well walking next to other dogs and even gives them kisses. Being so social and outgoing, he doesn’t need corrections along these lines. Human affection is something Duncan puts high value on, and he softens when you pet him. He still has some puppy habits, so may jump on you and try to give you kisses (a behavior that can readily be addressed with training). When it comes to personal preferences, Duncan definitely prefers female dogs over males. He is happy to be in the play yard and does well with calm females, but does not appreciate pushy males. In the end, he prefers to be on his own. If you have a loving home in which Duncan can be the only dog, or where there’s a calm female, then do apply for this gorgeous boy.
