Short answer: Keep your dog cool with shade, constant fresh water, walks during cooler hours, and never leaving them in a parked car. Replenish electrolytes on hot, active days, protect paws from hot pavement, and learn the signs of heatstroke — which is a medical emergency.
Signs of overheating and heatstroke
Watch for heavy panting, drooling, bright red gums, weakness, vomiting, disorientation, or collapse. Heatstroke can be fatal fast — act immediately if you see these signs.
How to keep your dog cool
- Water and shade always. Fresh water in multiple spots and shady rest areas.
- Replenish electrolytes on hot or active days so their body holds onto fluid, not just water.
- Time walks for early morning and evening; avoid midday heat.
- Check the pavement. If it's too hot for your hand for seven seconds, it's too hot for paws.
- Cooling mats, fans, and damp towels help at home.
- Never leave a dog in a parked car — temperatures spike within minutes.
Dogs at higher risk
Flat-faced breeds, seniors, puppies, overweight dogs, and those with heart or breathing issues overheat more easily and need extra care.
If your dog overheats
Move them to shade or air conditioning, offer small amounts of cool (not ice-cold) water, wet their body with cool water, and contact your vet right away — heatstroke needs professional care even if they seem to recover.
Frequently asked questions
How hot is too hot to walk a dog?
Use caution above about 80°F, and check pavement temperature. Walk during cooler morning and evening hours in summer.
Should I give my dog electrolytes in summer?
On hot, active days, a dog-formulated electrolyte supplement helps replace what's lost through panting and activity and supports hydration.
What are the first signs of heatstroke in dogs?
Heavy panting, drooling, bright red gums, and weakness are early signs. Disorientation or collapse is an emergency.
Can I put ice on an overheating dog?
Use cool water rather than ice-cold, which can constrict vessels. Cool gradually and get to a vet.
