Query: Back saver

Could not have been more satisfied with Dog Pack. Took my Lab with us on Elk Hunt in Wyoming he was able to carry more then his share. Also was able to help Pack out two Elk both times I would say at least 15 pounds. Saved our backs some extra weight. The Pack held up great did rub a little on his left front leg, that was probably my fault for not having it adjusted just right. I agree with past reviews go one size smaller, my Lab weighs 85lbs I went with a Medium. Gary
