Heat stroke in dogs: knowing when “too hot” becomes an emergency

One thing I wish every dog owner knew is that heat stroke isn't something to “wait and see” if your dog cools down on their own. Once a dog is showing signs of heat stroke, it can become a true emergency very quickly. Heavy or abnormal panting, excessive drooling, weakness, confusion, vomiting or diarrhea, stumbling, collapse, or a change in responsiveness are all signs to take seriously—especially after exercise or being outside in hot/humid weather. If you suspect heat stroke, start cooling your dog while arranging immediate veterinary care. Move them out of the heat and begin gentle cooling with cool/room-temperature water and airflow. Avoid ice or extremely cold water, which can cause blood vessels near the skin to constrict and interfere with heat loss. Don't delay veterinary care just because your dog seems to be improving. Prevention is huge. Don't rely only on the temperature itself—humidity, direct sun, exercise, lack of acclimation, and individual factors can all affect how quickly a dog overheats. Dogs with short noses, thick coats, certain medical conditions, or those who are overweight can be at higher risk, but heat stroke can happen to any dog under the wrong conditions. One of the easiest things you can do is learn your dog's normal behavior and breathing, plan outdoor activity around the weather, provide shade and water, and give them plenty of opportunities to cool down. As a general rule, if your gut is telling you something isn’t right, listen to it. You never need to worry that, “I might be overreacting", for calling your veterinarian or an ER when you’re worried about your pet.
