Dogs typically communicate with their humans in one of two ways: verbally or physically. Interpreting whines and wags becomes second nature after you get to know your dog. But when it comes to canine health, simple observation can be crucial. Frostbite is a cold weather injury that threatens a dog’s extremities and could be very painful for pups. It can be hard to tell if your dog has frostbite, so regularly inspecting her skin, paws, ears and tail is essential—as long as you know what to look for.
