Hypothermia

Hypothermia is a lowering of the core body temperature below the dog’s and cat’s normal 101.5-102.5 temperature. A first reaction to the lowering of temperature is to shiver. Shivering increases muscle activity, which in turn increase heat production. Mild hypothermia causes an increase in blood pressure and heart rate, but if the time and severity of heat loss continues, heart rate and blood pressure decline and cardiac arrest can occur. Severe hypothermia leads to respiratory depression, lethargy, lack of coordination, paralysis, and collapse. Treatment for hypothermia involves rapid warming of the body. In mild cases, heating pads, hot water bottles, or a warm water bath will do the trick, but severe cases require need veterinary attention immediately.
