I think my dog may have more dog coats than I do. We live in Minnesota and my dog has a good double coat himself but now that he's older he wears man-made coats more often. This coat is perfect for him for those blustery days with wind chill below zero in particular. It covers his bad hips, spine and core even in strong winds so, with the addition of boots, we can be out in any weather that Minnesota throws at us. It also keeps him warm and allows him to lie down comfortably when he needs to be in a car crate between runs for K9 scent detection games in cold weather. On walks, it makes him visible to vehicles, cross-country skiers, bikers and handlers of other dogs.
