Giant Newfoundland barrels down the stairs in search of best friend

What would it look and sound like if a bear ran down the stairs in your home? We get a good idea of that watching Samson the 160 pound Newfoundland when he hears his little girl and best friend Sierra calling for him. He is so heavy and lumbering as he jolts down the stairs, mom is afraid he’s going to run right into the wall. Once he gets downstairs, he quickly finds Sierra and announces it joyfully to the world. So sweet!
