So i get many mixed feeling from people about putting coats on their dogs. Many good and many bad. For some dogs it's not necessary to put a coat on but then you have your more gentle breeds on dogs that shiver in the cold and don't have a lot of fur to protect them from the harsh winter. My dog is a 70lbs Shepard mix and I put a coat on him because he gets chilly when walked outside and it quite obvious that he is cold. Think of it this way would you be ok with someone telling you, you don't need a coat because you have thick body hair. Dogs are meant to stay warm with their fur coats but breeding over the year can make the dog a little less tolerable to the cold because their are more and more a house pet not an outdoor animal like used before. With the many dog breeds out their that don't do good with the cold you need to get a coat for them.
