Sam is a healthy and happy Rottweiler/Black Lab mix. His mother was the Rottweiler. A coworker's dog had the litter of 8 puppies. I got Sam at about 6 months of age. He has all of his shots. He is not fixed. Sam needs a home where he can be outside in a large, fenced yard. He can get overheated during summer, so his habitat must include a shaded/sheltered area.
