Does your dog need to wear a coat outside in the winter? According to the Wall Street Journal, small, short-haired, inactive dogs without a thick fur undercoat are more susceptible to cold weather.
If you live with a lap dog such as a Chihuahua, dachshund, Boston terrier, shih tzu, bichon frise, miniature pinscher or the xolo, a Mexican hairless dog, a heavy winter sweater or coat is a must. And, regardless of their breed, elderly or sick pets may need to wear extra layers outside.
Working and sporting dogs are generally heartier and less likely to need the protection. Bigger breeds, such as Retrievers, Shepherds, Huskies, are bred for outdoor life and work and function better outdoors au naturel, but still need to stay active and be able to curl up in a sheltered area.
