Buck is one of the biggest of the brown puppies; he is mostly dark brown with a tiny bit of white on chest and paws, plus a micro amount on the tip of his tail. Has some black on stomach, tail, and muzzle. He will be 5 weeks old on Saturday, January 18th. He has a cute red collar! His mom is a purebred, AKC, black, and longhaired German Shepherd that loves kids and her family and is a great guard dog. His dad is a purebred, AKC registered Rough Collie, and is smart and loving. Their last litter of puppies all are loved by their new families, and one even became a beloved service dog. Buck will be ready to go on Valentine's Day.
