It looks like this weekend Summer is going to be heating up...which is a good time to remind pet-parents about the dangers of Heat Stroke in our four-legged friends. Could you imagine wearing a winter coat when it is 90° outside? That is what it is like for them during the summer. What is Heat Stroke? Heat stroke is a term used for hyperthermia or elevated body temperature. If your pet's body temperature is at 103°F or above, that is considered abnormal or hyperthermic. When the body temperature reaches 106°F without previous signs of illness and is most commonly associated with exposure to excessive heat that is often referred to as heat stroke. What Causes Heat Stroke? Many people believe that heat stroke is limited to when a dog is confined in a small or enclosed place during high temperatures, such as a car. Yes, this can be the most common cause but there are also many others. Your dog can be affected by moving from cool places (like the A/C in the house or car) to outside. Extreme exercise and outdoor play can induce heat stroke as well. What are the Symptoms of Heat Stroke?
