However, just like people, dogs can become overheated. A dog's normal body temperature is 100.5 to 102.5 degrees Fahrenheit. If it rises to 105 or 106 degrees, the dog is at risk for developing heat exhaustion. If the body temperature rises to 107 degrees, the dog has entered the dangerous zone of heat stroke. With heat stroke, damage to the body can be irreversible.
Organs begin to shut down, and veterinary care immediately needed.
Fortunately, if owners recognize heat exhaustion, they can prevent the dog from entering heat stroke. People can easily recognize when the heat gets to them because they become lightheaded and fail to sweat. For dogs, early signs of heat exhaustion may include failure to salivate and a dry. Heat exhaustion may also include a dog lying down and looking tired, losing its appetite, and becoming unresponsive to owners. If heat exhaustion progresses into heat stroke, the dog becomes very warm to touch and may have seizures.
