A Bernese Mountain Dog (100# plus) used to be a playmate for my 38 pound Lab. They would bump chests and it would knock Shelley sprawling, and she would jump up and go back for more. They had a wonderful time together - Labs are quite durable.
Yeah, my Labs are on the small side for Labs (38, 52, and 56 pounds) and probably all three of them might make one of yours!
Almost, but a little shy. My smallest dog weighed 166 lbs at her last weigh in. My biggest boy is 228 lbs.
