Although we know that dogs are descended from the mighty wolf, different dog breeds exhibit a huge variety of characteristics. While some breeds can pull sleds around the Alaskan tundra and face the cold weather, other pups were meant to stay bundled up inside this winter.
The data experts at pet data site PetBreeds used data from Animal Planet and the American Kennel Club to find the 31 most popular breeds that can't handle the cold weather. These dogs are qualified as the least cold tolerant, or "1" (Animal Planet measures on a scale of 1-low tolerance, 2-medium tolerance and 3-high tolerance). Dog breeds are ranked by their popularity in 2015, based on information from the American Kennel Club.
Most of these canines have short fur (or none at all) and not enough body fat to keep them cozy in freezing temperatures. Size, however, is not a determining factor. Of course, tiny breeds like Chihuahuas and Shih Tzus would prefer to stay curled up on the couch, but larger dogs like Weimaraners and Great Danes do not handle cold temperatures well, either.
If you're thinking about getting one of these dogs over the holidays, make sure you have room for them under the covers or on your lap.
