Some dog breeds definitely require a little extra protection and warmth in the cold weather. Dog owners living in a region experiencing cold climate would definitely want to take a dekko at the below list consisting of various dog breeds that are sensitive to chilly weather. The makeup of the dog has lots to do with how it tolerates lower temperatures. A dog with thin coat will feel the effects of severe winters greatly.

Great Dane: This gentle giant’s origin dates back to 3000 B.C backed by its drawings on ancient artifacts. The breed has short hair over its huge body and is not very good at tolerating the cold. 

Beagle: This breed has short hair; however the coat may get a bit dense in winter weather.
