Frostbite begins when the dog’s body gets cold. The body pulls blood from the extremities to the center of the body to stay warm. The dog’s ears, paws or tail can get so cold that ice crystals will form in the tissue and damage it.
The other very serious winter weather health concern for dogs is hypothermia. Hypothermia occurs when a dog spends too much time in the cold, gets wet in cold temperatures or when dogs with poor health or circulation are exposed to cold. In mild cases, the dog will shiver and ears and feet will become cold.
Some dog breeds are blessed with thick fur that keeps them warm naturally in very cold temperatures, but dogs with thin coats may need to wear a sweater or coat when out for winter walks.
