Signs of Overheating and How to Respond
Watch all dogs for symptoms of heatstroke, such as restlessness, excessive thirst, heavy panting, lethargy, lack of appetite, dark tongue, rapid heartbeat, fever, vomiting, and lack of coordination. If a dog shows any of these symptoms, get him or her into the shade immediately and call animal control or the police (if the dog is not your companion) or your veterinarian (if the dog is your companion). Lower the animal’s body temperature gradually by providing water to drink; applying a cold towel or ice pack to the dog’s head, neck, and chest; or immersing the dog in lukewarm (not cold) water.
