via the daily puppy Puppy Breed: Newfoundland Cass is a goof ball! He has never met a person or dog he does not love and his favorite past times are laying on his big dog bed and playing with his glow in the dark ball. He also loves sleeping because he is growing so much! He is already 70 pounds at 4 months old. Our lives were changed for the best the day we brought Cass to the big city of Chicago and we haven't looked back! Cass is the best!
