Unlike humans, dogs can't sweat to cool down — they rely mainly on panting to regulate body temperature. That makes them far more vulnerable to heat, and heatstroke is one of the most common summer emergencies that lands dogs in the ER.
1. Early signs of heatstroke
- Panting that's much heavier and faster than usual
- Excessive or thick, sticky drooling
- Gums turning bright red or purple
- Stumbling, lethargy, or slow responses
- Vomiting or diarrhea
Flat-faced breeds (bulldogs, pugs, etc.), senior dogs, and overweight dogs are all at significantly higher risk, so extra caution is needed for them.
2. Summer prevention checklist
- Adjust walk times: Avoid midday (11am–5pm) and walk in the early morning or evening instead.
- Check the pavement: Press the back of your hand to the asphalt for 5 seconds — if it's too hot for you, it's hot enough to burn your dog's paws.
- Never leave your dog alone in a car: Even with a window cracked, the temperature inside a car can spike to dangerous levels within minutes.
- Keep fresh water available: Bring a portable water bottle and bowl on every outing.
- Shade and airflow: Keep indoor spots out of direct sunlight, and manage temperature with ventilation or air conditioning.
3. Emergency steps if you suspect heatstroke
- Move your dog to a cool, shaded area (or an air-conditioned room) immediately.
- Wet the body — especially the belly, paw pads, and inner ears — with lukewarm or cool water, not ice water. (Cooling too fast can trigger shock.)
- Use a fan to help lower body temperature naturally through airflow.
- If your dog is conscious, offer small amounts of water, but don't force them to drink.
- Once you've confirmed the symptoms, call a nearby vet while you're already on your way and let them know you're coming. With heatstroke, every minute matters.
Most summer heatstroke cases are entirely preventable. Managing walk times and indoor conditions goes a long way toward keeping the risk low.
