Frostbite can occur in both dogs and cats, in fact, we generally see it more often in cats. The parts of the body most likely to be frozen are the ears, and sometimes the tail and feet. Initially, areas damaged by frostbite appear normal. Within 48 hours, though, the damaged tissue will swell and become painful. Within 7 days, due to interruption of the blood flow and nerve supply, the affected tissue dries up and turns black, eventually falling off twenty to thirty days later.
Frostbite can be minor or severe.
Death may result if the limbs are involved. Dying tissue attracts bacteria, and severe, life-threatening infections can result. If frostbite is suspected, it is best to immediately, but slowly warm the animal. Do not place the animal in hot water or other areas of extreme temperatures. Do NOT rub the area.
