All our litters are whelped in our home. The puppies are socialized to become GREAT FAMILY PETS. The pups are born with blue eyes that will turn yellow or pale green as they get older. Silver and Charcoal gray coats will stay that color through out their entire life. Coat colors may vary slightly with the change of seasons. As one happy owner said "Not only do I have the best dog in the world, I am also the most popular guy in my neighborhood!"
