Heat exhaustion in dogs is serious and can quickly lead to heatstroke, which is life-threatening. It’s crucial to know the warning signs so you can act fast. Here’s how to tell if your dog is overheating:
🔴 Signs of Heat Exhaustion in Dogs
- Excessive panting – Faster, heavier breathing than normal
- Drooling – Thick, sticky saliva
- Bright red gums or tongue
- Lethargy – Weakness, collapse, or reluctance to move
- Vomiting or diarrhea – Sometimes with blood
- Increased heart rate
- Staggering or uncoordinated movements
- Glassy eyes or dazed expression
- Fever – A dog’s normal temperature is 101–102.5°F; above 103°F is too high
- Unresponsiveness or confusion in advanced stages
🐾 What to Do if You Suspect Heat Exhaustion
- Get your dog out of the heat immediately – Into shade or air conditioning
- Cool them down gradually – Use cool (not ice-cold) water on the body, especially belly, paws, and underarms
- Offer small amounts of cool water – Don’t let them gulp it
- Use a fan to help with evaporation
- Call a vet right away – Especially if symptoms are severe or don’t improve within minutes
🧊 What Not to Do
- Do not use ice or ice-cold water (it can constrict blood vessels and trap heat)
- Don’t force water down their throat
- Don’t wait—heatstroke can cause organ damage or death in minutes
✅ Prevention Tips
- Avoid walks in the heat of the day
- Provide plenty of fresh water and shade
- Never leave dogs in cars
- Use cooling vests or mats on hot days
If you’re unsure, it’s always safer to call a vet. Dogs can’t cool down like humans, and heat issues can become deadly fast.
