Heres my pup back in Oregon. His name is Bernie and he is a mix of bernez mountain dog(didnt know what he was when we named him bernie haha) chow and possibly some newfoundland. Greatest dog I have ever had, and he has the most character of a dog I have ever seen also, he loves to use his paws to do stuff its really funny. Anyways hes around 9 years old and weighs 90lbs.
He also has webbed feet and loves the rain and swimming. Gotta be careful tho because if he see's a part of the family in the water pretty far out he'll take off after them and swim around you until you grab his leash and he'll start heading back to shore.
