We often think that animals can endure extreme temperatures due to their thick coats but even animals have their limits. Animals are still prone to frostbite and hyperthermia, and can also become ill due to low temperatures. A man saw a dog freezing in the cold all alone and what he decided to dog saved the dog’s life. He hugged the dog in -20 degrees Fahrenheit and shared his body heat with the dog. He warmed up the shivering dog and potentially saved its life.
