You’re sitting outside on a warm afternoon, feeling the sun on your skin, and your dog is right there beside you, panting away. And you wonder: is he actually hot right now? Does he feel the heat the way I do?
The short answer is yes, dogs absolutely feel hot. But they experience and handle heat very differently from us. And because they can’t tell you when they’re uncomfortable, it’s up to you to notice the signs and step in before things get serious.
Let’s walk through how dogs experience heat, what overheating looks like, and what you can do to help.

Do Dogs Actually Feel Heat?
Yes, they do. Dogs feel temperature changes just like we do. They have nerve endings in their skin that detect warmth and cold. The difference is in how they respond to it and how efficiently they can cool down.
A dog’s normal body temperature sits between 38°C and 39.2°C (100.4°F to 102.5°F), which is already higher than ours. So while they do feel ambient heat, their starting point is warmer, and their cooling system is far less efficient than human sweating.
How Dogs Regulate Their Body Temperature
Here’s the thing: dogs don’t sweat the way people do. They only have sweat glands in their paw pads, which helps a little but not nearly enough on a hot day.
Their main cooling method is panting. When a dog pants, moisture evaporates from the tongue and respiratory tract, releasing heat. It works reasonably well in mild warmth, but when the air is very hot or humid, panting becomes much less effective.
Dogs also seek cool surfaces instinctively. You’ve probably noticed your dog sprawling on tile floors or digging into shaded dirt. That’s not random, it’s active temperature regulation.
Signs Your Dog Is Feeling Hot
Since your dog can’t say “I’m boiling,” you need to watch for behavioral and physical cues. Some signs that your dog is feeling uncomfortably warm:
- Heavy or rapid panting, more than usual for the activity level
- Seeking shade or cool surfaces
- Drinking more water than normal
- Lying flat on cool ground with legs spread
- Slowing down on walks or refusing to move
- Red or flushed gums and tongue
- Drooling more than usual
These are early signals. Most of the time, if you notice them and respond (shade, water, rest), your dog will be fine. The key is not ignoring them.
When It Becomes Dangerous
There’s a difference between a dog feeling warm and a dog in heat distress. Heatstroke is a medical emergency, and it can escalate quickly.
Warning signs of heatstroke include:
- Excessive, frantic panting that doesn’t slow down
- Bright red or purple gums
- Thick, sticky saliva
- Vomiting or diarrhea
- Staggering, confusion, or disorientation
- Collapse or inability to stand
- Glazed eyes or unresponsiveness
If you see these signs, act immediately. Heatstroke can cause organ damage or be fatal within minutes. This is not a “wait and see” situation. Get your dog cooled down and contact your vet right away.
What to Do If Your Dog Is Overheating
If your dog is showing signs of overheating (but not yet in crisis), here’s what helps:
- Move them to shade or an air-conditioned space immediately
- Offer cool (not ice-cold) water to drink
- Wet their paws, belly, and ears with cool water
- Place a damp towel over them, but don’t wrap them tightly
- Use a fan to help with evaporation
- Let them rest completely
Avoid using ice water or very cold water. It can cause blood vessels to constrict, which actually traps heat inside the body. Cool and gradual is the way to go.
If symptoms are severe or your dog doesn’t improve within a few minutes, call your vet or go to an emergency clinic. Don’t wait it out.
How to Keep Your Dog Cool
Prevention is always easier than treatment. On warm days, a few simple habits make a big difference:
Adjust walk times. Walk early in the morning or later in the evening when the ground is cooler. Pavement can reach 60°C+ (140°F+) in direct sun, which burns paw pads and radiates heat upward.
Provide constant access to fresh water. Carry a portable bowl on walks and keep bowls refilled at home. Add an ice cube or two if you like.
Create cool resting spots. A shaded area with good airflow, a cooling mat, or access to tiled flooring all help.
Never leave your dog in a parked car. Even with windows cracked, a car’s interior can reach lethal temperatures within minutes. This is one of the most common causes of fatal heatstroke in dogs.
Limit intense exercise. On hot days, skip the fetch marathon. A gentle sniff walk in the shade is plenty.
Consider a kiddie pool or sprinkler. Many dogs love splashing around, and it’s an easy way to bring their temperature down while having fun.
Which Dogs Are More at Risk
All dogs can overheat, but some are more vulnerable than others:
- Brachycephalic breeds (Bulldogs, Pugs, French Bulldogs, Boxers) have shorter airways, making panting far less efficient
- Senior dogs and very young puppies have weaker thermoregulation
- Overweight dogs retain more heat and tire faster
- Thick or double-coated breeds (Huskies, Malamutes, Samoyeds) carry extra insulation
- Dogs with heart or respiratory conditions are less able to cope with heat stress
- Dark-coated dogs absorb more heat from sunlight
If your dog falls into any of these categories, be extra cautious during warm weather. Shorter outings, more shade, and closer monitoring go a long way.
Frequently Asked Questions
What temperature is too hot for dogs?
Generally, temperatures above 27°C (80°F) require caution, especially with humidity. Above 32°C (90°F), most dogs should be kept indoors or in deep shade with water access. Brachycephalic and at-risk breeds may struggle even at lower temperatures.
Can I shave my dog to keep them cool?
It depends on the coat type. Double-coated breeds (like Huskies or Golden Retrievers) actually rely on their undercoat for insulation against both cold and heat. Shaving them can disrupt this and even increase sunburn risk. Talk to your vet or groomer before shaving.
Do dogs sweat at all?
Only through their paw pads. It contributes very little to overall cooling. Panting is their primary method of releasing heat.
How can I check if the pavement is too hot for my dog?
Place the back of your hand flat on the ground for 7 seconds. If it’s too hot for you to keep it there, it’s too hot for your dog’s paws.
Should I put ice in my dog’s water?
A few ice cubes in their water bowl are fine and many dogs enjoy it. The myth that ice water causes bloat has not been supported by veterinary evidence. Just don’t force ice-cold water on a dog already in heat distress.
Your dog counts on you to notice when the heat is getting to them. The good news is that with a little awareness and some simple adjustments, keeping your dog comfortable and safe in warm weather isn’t complicated. Watch for the signs, offer shade and water, and save the long adventures for cooler hours. That’s really all it takes.
