Dogs have feelings, just like you do. They just have a hard time expressing said feelings because of the language barrier that lies between humans and dogs. You can rest assured, however, that every time you look at your dog it is thinking about you and its surrounding environment. So what do you think happens when your dog is cold? It sits there and bears it because it can’t do anything else! You should take it as a matter of course that if you’re cold, your dog is cold too. That’s why your small dogs need small dog coats . The small dog coats allow your dog’s body heat to be recycled resulting in much warmer and much happier dogs.
