We bought Tucker a coat just because we got one for our German Shepherd, who is a senior with arthritis, to keep her warm since she doesn't tolerate the cold as well as she used to. I never really thought that Tucker would NEED a coat, but I will admit that it can get VERY cold here in Maine during the middle of the winter and we are very active and take long walks and hikes in the woods, so I guess it might be beneficial just to keep him extra warm. He's only 15 months old and doesn't have his full adult coat yet, so this should provide some extra protection from the extreme cold and windchills while we're on our walks. I'm not the type of person to dress up my dogs at all, but he actually looks kind of good in his coat! It's simple and not flashy at all.
