Many popular breeds of dogs grow a thick coat during the freezing season of the year to provide protection against the cold, wind and rain. But this is not the case for all dogs by far! Just like people, you will find a “chilly willy” or two here. Dogs will generally let you know when they have gotten too cold outside. If your pet regularly casts a reproachful look at you while standing rigidly in the hallway, you may want to invest in a source of warmth like a dog blanket to ensure that walks remain fun in the autumn and winter.
