What to Do With Dogs When It's Too Hot (Summer Safety)

When it's too hot, move your dog's day indoors, shift anything strenuous to the coolest hours at dawn or after dark, and replace physical exercise with mental work. Keep fresh water in more than one bowl, keep air moving, limit outdoor trips to short potty breaks on grass rather than pavement, never leave a dog in a parked car even briefly, and learn the early signs of heat stress so you can act before it becomes an emergency. A missed walk costs your dog nothing. A heat emergency can cost everything.

Dogs are badly equipped for hot weather. They shed heat mainly by panting, with a small contribution from the blood vessels in their ears and the sweat glands in their paw pads. That cooling system depends on evaporation, which is why humid heat is far more dangerous than dry heat at the same temperature. Dogs also wear a permanent coat, run closer to hot ground than you do, and, the part that catches most owners out, will keep chasing a ball long past the point where their body is in trouble. The judgement has to come from you.

How hot is too hot: read the conditions, not just the thermometer

There is no single temperature that flips the switch, because the number on your weather app is only one of five variables that matter.

Humidity is the big one. When the air is already saturated, panting stops working, and a dog can be in serious trouble on a day that feels merely warm to you. Shade and surface matter next: open asphalt, sand, artificial turf and bare concrete radiate heat upward into a body that sits inches above them, while a shaded woodland trail can be dramatically more forgiving. Airflow changes everything, still, heavy air in a yard or a parked car is a different environment from a breezy field.

Then there's the dog in front of you. A lean, fit, young dog with a short coat and a long muzzle handles heat differently from a flat-faced dog, a senior, an overweight dog, a thick double-coated breed, or a dog with heart or airway disease. Finally, intensity: a slow sniff-walk and a game of fetch are not the same activity in the heat. Fetch, in particular, lets a dog redline before anyone notices.

If you want a practical rule, use this one: on any day that feels uncomfortably warm standing still in the sun, treat exercise as off the table until the temperature drops and the ground has cooled. Your veterinarian can help you set a more specific threshold for your individual dog, especially if there's an existing airway, heart or mobility issue in the picture.

The five-second pavement test takes less time than clipping the leash

Press the back of your hand flat against the pavement and hold it for five to seven seconds. If you can't keep it there comfortably, your dog can't walk on it. Paw pads are tough, but they are skin, and they burn.

Ground surfaces hold heat long after the air has started to cool, which is why an 8pm walk in a heatwave can still cook a dog's feet. Asphalt, dark paving slabs, metal truck beds, sand and rubberised turf are the worst offenders. Grass, damp earth and shaded dirt trails are far safer.

Signs of burned pads include limping, refusing to walk, licking or chewing at the feet, pads that look darker than usual or visibly blistered, and missing patches of pad surface. If you see any of that, keep the dog off the surface, cool the feet with cool water and call your veterinarian: pad burns can become infected and are genuinely painful.

Practical fixes: route the walk on grass, go out at first light, use properly fitted boots if your dog will tolerate them (introduce them indoors first, weeks before you need them), and shorten the walk rather than pushing through.

Indoor days: what to do instead of the walk

A dog who misses a walk isn't deprived. A dog who misses a walk and gets nothing else is bored. Replace the physical outlet with a mental one and most dogs settle faster than they would after a lap of the block.

Scatter a handful of kibble across a towel or snuffle mat and let them work it. Hide treats around a room and send them to find. Run short training sets, three minutes of nose touches, mat work, or a new trick, and stop while they're still keen. Food puzzles, frozen stuffed toys and lick mats all slow a dog down and give them something to do. Indoor recall between two people down a hallway burns more energy than it looks like it should.

For the cooling itself, here's how the common approaches actually compare:

Approach	What it does	Watch-outs
Air conditioning plus hard floors	Lowers ambient temperature and gives a conductive surface to dump heat into; the most reliable option	Keep the dog out of direct sun through windows; tile and stone beat carpet
Fan with a damp coat or wet fur	Moves air across evaporating moisture, which is where the cooling actually happens	A fan aimed at a dry, furred dog does very little, wet the dog first
Cooling mat	Passive conduction away from the belly and chest; useful for crates and car travel	Some dogs chew them; gel ingestion is a vet call. Check the mat is still cool before assuming it is working
Shallow paddling pool or hose-down	Wetting the belly, groin, armpits and paws moves heat quickly from thin-skinned, high-blood-flow areas	Supervise always; never force a water-averse dog; empty the pool between uses
Frozen enrichment	Occupies the dog and adds cold fluid intake	Counts toward daily calories; rock-hard frozen items can risk tooth damage in power chewers
Evaporative cooling vest	Helps in dry, moving air for short outings	Needs to stay wet to work and can trap heat once dry or in high humidity

Water deserves its own line. Put out more bowls than usual, in more rooms, and refresh them. Dogs drink more when water is cool and close by. Add water or broth to food if your dog is a reluctant drinker, and talk to your veterinarian if intake drops noticeably during hot weather.

Heat stress warning signs and when to call the vet

Heat illness runs on a spectrum, and the early end is easy to dismiss as a dog just being hot.

Early signs: heavy, relentless panting that doesn't settle with rest, bright red gums and tongue, thick ropy drool, slowing down or lagging behind, seeking shade or refusing to move, and restlessness.

Progressing signs: wobbliness or an unsteady gait, vomiting or diarrhoea (sometimes bloody), glassy eyes, confusion or not responding to their name, gums that turn pale, grey or bluish, collapse, and seizures.

If your dog is panting frantically, staggering, or their gums look brick-red, grey or blue, stop everything and get to a veterinarian immediately: heat stroke is an emergency where minutes matter.

While you're arranging that: get the dog out of the sun and into air conditioning or shade, pour or run cool, not ice-cold, water over the body, concentrating on the belly, groin, armpits and paws, and get air moving across the wet fur. Don't wrap the dog in soaked towels and leave them on; trapped heat defeats the purpose. Offer small amounts of cool water if the dog is conscious and willing, but never force water into a dog that is disoriented.

One more thing owners frequently get wrong: a dog who seems to bounce back still needs examining. Heat injury can cause delayed problems with clotting, kidneys and the gut that don't show for hours. Call the clinic even if the crisis appears to have passed.

Dogs that need a wider safety margin

Some dogs have far less room for error: flat-faced breeds whose airways restrict airflow before panting even starts, seniors, very young puppies, overweight dogs, thick double-coated and dark-coated breeds, and dogs with heart disease, laryngeal paralysis or any chronic airway condition. For these dogs, hot weather isn't a scheduling inconvenience: it's a genuine risk, and the plan should be made with your veterinarian before the first heatwave rather than during it.

Dogs in orthopaedic recovery sit in an awkward middle. Controlled leash walking is often a backbone of post-operative rehab after cruciate surgery or a soft-tissue injury, and summer forces those sessions into narrow windows at dawn and dusk, sometimes shorter than the protocol calls for. Don't quietly drop them and don't double up later to compensate: ask your vet or rehab vet how to adapt the loading plan to the weather, because consistent, graded loading is what guides tendon and ligament tissue as it remodels over weeks.

Many owners also look at what they can support alongside that plan. pawgen makes K9-REPAIR, a BPC-157 and TB-500 peptide formulation for dogs. BPC-157 is a peptide studied in animal models of tendon, ligament and soft-tissue repair; TB-500 relates to thymosin beta-4, a naturally occurring protein involved in actin regulation, cell migration and tissue remodelling. Research suggests these mechanisms may support the body's own soft-tissue repair processes, and it's the stack a growing number of owners adopt through recovery periods. These are not FDA-approved veterinary drugs, nothing here is a substitute for surgery, a prescription or your vet's rehab plan, and you should talk to your veterinarian before adding anything. Every batch is third-party tested with certificates of analysis published, and it ships direct to your door with a 60-day money-back guarantee.

Key Takeaways

• Humidity, surface temperature, airflow and your individual dog matter more than the air temperature alone.
• Use the five-second back-of-hand pavement test every time before a hot-weather walk.
• Skipping a walk is free; replace it with scent work, food puzzles and short training sets.
• Wetting the belly, groin, armpits and paws plus moving air cools a dog far faster than a fan alone.
• Bright red or grey gums, staggering, confusion or collapse mean emergency veterinary care now.
• A dog that appears to recover from overheating still needs a veterinary exam.
• Flat-faced, senior, overweight, heavy-coated and post-surgical dogs need a much wider margin.

Your veterinarian owns the diagnosis and the treatment plan: the heat threshold for your specific dog, the rehab protocol after surgery, the prescriptions that keep a chronic condition stable. Everything else, including supplements and peptides, works inside the space proper veterinary care creates, never instead of it.
