Why Heat Changes the Rules
Dogs don't sweat through their skin — their main thermoregulation mechanism is panting. This makes them far more vulnerable to heat than we are during exercise. A dog running at 30°C (86°F) generates body heat faster than it can dissipate through panting — heatstroke can develop in minutes.
Safe Exercise Windows in Summer
| Time | Risk | Recommendation |
|---|---|---|
| Before 8 am | Low | Ideal for moderate exercise |
| 8–10 am | Moderate | Short walks, shade, water |
| 10 am–7 pm | High/Very high | Outside only for toilet breaks |
| 7–8 pm | Moderate | Wait for pavement to cool |
| After 8 pm | Low | Ideal for long walk or run |
Pavement test: place the back of your hand on the ground for 7 seconds. Too hot for you = too hot for your dog's paws.
Safe vs. Dangerous Surfaces
- ✅ Grass, dirt, woodland trails, damp sand.
- ⚠️ Dry sand (can be very hot + burns paw pads).
- 🚫 Tarmac, paving stones, concrete between 10 am and 8 pm.
Adapting the Exercise Routine to Summer
Running and active sport
- Only before 9 am or after 8 pm.
- Natural surfaces whenever possible.
- Always carry water; stop every 10–15 minutes.
- Reduce distance by 30–40% compared to cooler months.
- Watch panting rate — if it increases dramatically, stop and offer water.
Toilet walks during the heat
- As short as possible — just enough for the dog to relieve themselves.
- Always seek shade and tree cover.
- Carry water even for a 5-minute outing.
Mental exercise as a substitute
- Scent work: hide treats around the house, use a snuffle mat or stuffed Kong. 15 minutes equals 1 hour's walk for mental fatigue.
- Obedience training: 10–15 minute sessions of new tricks indoors with a fan or air conditioning.
- Hide and seek: hide the favourite toy in different rooms.
- Food-dispensing toys: treat balls, lick mats, puzzle feeders (Levels 1–3).
Warning Signs During Exercise
Stop immediately and find shade if you see
- Very intense, fast panting even while standing still.
- Excessive, foamy drooling.
- Very red or purple gums.
- Stumbling or staggering.
- Frantic search for shade or cool ground.
Emergency — emergency vet immediately
- Vomiting or diarrhoea during exercise.
- Confusion or disorientation.
- Tremors or seizures.
- Loss of consciousness.
While travelling to the vet: wet the groin, armpits, neck and paw pads with fresh (not ice cold) water. Do not pour water into the mouth of an unconscious dog.
Log your dog's daily exercise duration and type in Purzi. If you notice a change in energy or behaviour after activity, you will have the exact context ready for the vet.
