Your dog, believe it or not, gets cold too. Its fur isn’t nearly as beefy as it looks. Dog’s ancestors spent years and years adapting their fur and bodies to the temperatures that they lived in. You, as the owner, then took the dog out of its natural habitat. Because of this, your dog is NOT adapted to where you live. If you live in a relatively cold climate and your dog shivers when out in the cold, you should definitely consider buying dog sweaters . Dog sweaters will not only make your dog look so adorable, it will also make him oh so warm.
