Yukon and Cheyenne von Bark Ave are adorable 3 month old German Shepherd puppies. Yukon is a white German Shepherd, he has big bones and will be on the large side. He is confident and outgoing; he is a funny guy with lots of personality. Don’t expect him to entertain himself all day alone, he needs something to do and someone to play with. His sister, Cheyenne, is adorable but not as out going. She needs a gentle family to love her and to nurture her. She is going to be on the large side as well. She is such a love!
