Overheating in Dogs: Signs of Heatstroke & How to Keep Dogs Cool


As temperatures rise, it's important to know how to protect your dog from overheating. Dogs are much more vulnerable to heat than humans because they can't cool themselves by sweating. Instead, they rely mainly on panting and releasing small amounts of heat through their paw pads.

Without the right precautions, hot weather can quickly lead to heat exhaustion or heatstroke, both of which can become life-threatening. Knowing the warning signs and acting quickly can help keep your dog safe all summer long.

Signs of Overheating and Heatstroke in Dogs

Early recognition is essential. Watch for these common signs of overheating in dogs:

  • Excessive panting or difficulty breathing
  • Heavy drooling
  • Bright red or dark red gums and tongue
  • Weakness, lethargy or unsteady walking
  • Vomiting or diarrhoea
  • Confusion or disorientation
  • Collapse or unconsciousness

If your dog shows any of these symptoms, move them immediately to a cool, shaded area and begin cooling them with cool (not ice-cold) water. Contact your vet as soon as possible, as heatstroke is a medical emergency.

How to Cool Down an Overheated Dog Safely

Cooling your dog correctly is just as important as recognising the symptoms.

To help lower your dog's body temperature:

  • Use cool, fresh water rather than ice-cold water.
  • Wet your dog's legs, paws, belly and chest first.
  • Offer fresh drinking water if they are able to drink.
  • Move them into the shade or an air-conditioned space.
  • Continue cooling while seeking veterinary advice.

Avoid covering your dog with soaking wet towels, as these can trap heat once they begin to warm up.

Keeping Dogs Cool During Walks

Prevention is always better than treatment. During warm weather:

  • Walk early in the morning or later in the evening.
  • Avoid hot pavements that can burn paws.
  • Carry fresh drinking water on every walk.
  • Take regular breaks in shaded areas.
  • Watch closely for signs of overheating.

Having cool water available while you're out can make a big difference, especially on longer walks or adventures.

A Practical Way to Keep Your Dog Cool Outdoors

Many dog owners already use the Mud Daddy portable washer to rinse muddy paws after walks, but it can also be useful during hot weather.

Filled with cool water, it provides a gentle way to rinse your dog's paws, legs and underside when they need cooling down. Adding the insulated jacket helps keep the water cool for over five hours, making it useful for summer walks, beach trips and days out.

Because it's portable, quiet and doesn't require electricity, it's easy to take wherever your adventures lead. During colder months, the same insulated jacket helps keep water warm for more comfortable winter rinses, making it a useful year-round accessory.

Summer Safety Tips for Dogs

Follow these simple tips to reduce the risk of overheating:

  • Walk during the coolest parts of the day.
  • Always provide access to fresh drinking water.
  • Make sure your dog has plenty of shade.
  • Never leave a dog in a parked car, even for a few minutes.
  • Use cooling mats or damp towels at home.
  • Carry water to cool your dog when you're out.
  • Avoid strenuous exercise during the hottest part of the day.

Frequently Asked Questions

How do I know if my dog is overheating?

The most common signs include excessive panting, heavy drooling, weakness, red gums, vomiting and collapse. If you notice these symptoms, begin cooling your dog immediately and contact your vet.

Can I use ice water to cool my dog?

No. Very cold or ice water can cause blood vessels to constrict, making it harder for your dog to cool down. Use cool, fresh water instead.

What temperature is too hot to walk a dog?

Many vets recommend taking extra care once temperatures reach around 20°C, particularly for older dogs, puppies and flat-faced breeds. At 24°C and above, the risk of overheating increases significantly, especially during exercise.

Keep Your Dog Safe This Summer

Hot weather doesn't have to stop your adventures. By recognising the signs of overheating, carrying fresh water and planning walks during cooler parts of the day, you can greatly reduce the risk of heatstroke.

Whether you're washing off muddy paws or helping your dog cool down after a warm walk, having a portable water system available can make outdoor adventures safer and more enjoyable throughout the year.
