Dog summer safety starts with prevention: provide fresh water and a cool, shaded, ventilated place to rest; avoid exercise during the hottest part of the day; never leave a dog in a parked car; and adjust plans for humidity, surface heat and your dog’s individual risk. If you suspect heatstroke, begin cooling and contact a vet immediately.

Heatstroke is an emergency. Relentless panting, breathing distress, drooling, vomiting, diarrhoea, confusion, staggering, weakness, seizures or collapse after heat exposure or exercise need urgent action. Stop activity, move to a cooler area, start cooling with water and a breeze, and call the nearest vet. Use our dog heatstroke first-aid guide.

What temperature is too hot for dogs?

There is no single safe or unsafe air temperature for every dog. Humidity, radiant heat, airflow, shade, exercise, acclimatisation, coat, age, body condition and health all change the risk. RSPCA Australia also notes that heatstroke can develop in cooler weather when other risk factors are present.

Do not use one internet temperature chart as permission to walk. Check the local forecast and heatwave information from the Bureau of Meteorology, then assess the actual conditions and your dog.

A dog with flat-faced anatomy, breathing or heart disease, obesity, a thick coat, very young or old age, or limited ability to move to a cooler place may need a much more conservative plan. Ask your vet for individual guidance if your dog has risk factors.

Your Australian summer safety checklist

Risk Preventive action Do not rely on
Hot weather and humidity Reschedule exercise and provide a cool retreat Air temperature alone
Parked vehicles Leave your dog safely at home rather than in the car “Just a minute”, shade or a cracked window
Hot pavements and ute trays Choose cooler times and surfaces; check before contact A hand test as a guarantee of safety
Dehydration Keep fresh water available at home and carry water on outings Assuming every dog will drink enough when stressed
Over-exertion Reduce intensity, stop early and use indoor enrichment Waiting for collapse before stopping
Poor ventilation Use shade with airflow, cooling or air-conditioning Shade that becomes hot and stagnant
Power or travel disruption Prepare a backup cool location and emergency contacts A cooling product as the only plan

Plan walks around conditions, not the clock

Early morning or later evening is often cooler, but those times are not automatically safe during a heatwave. Check current conditions, humidity and the temperature of walking surfaces. Choose shaded grass or another cooler route, shorten the outing and keep the pace easy.

Skip vigorous fetch, running, hill work and long sessions in hot or humid weather. Bring water and a bowl, offer rest in shade and go home before your dog is struggling. A dog that slows down, seeks shade, lies down or repeatedly stops is communicating that the outing should end.

Hot pavements, sand, artificial turf and metal ute trays can burn paws and increase heat load. If a surface feels too hot for comfortable contact, do not let your dog stand or walk on it. The common hand test is only a screening prompt; it does not measure every surface or guarantee that conditions are safe.

Never leave a dog in a parked car

A parked vehicle can heat rapidly, even when the day feels mild. Parking in shade, leaving windows open or planning a short stop does not make it a safe holding place for a dog.

The safest plan is to avoid the situation entirely:

  • leave your dog in a cool, secure place at home;
  • use a pet-friendly destination where your dog can stay with you;
  • ask another responsible person to care for them; or
  • postpone the trip.

If you find a dog in distress in a vehicle, contact local emergency services or the relevant animal authority immediately and follow their instructions. Laws and reporting contacts differ by state and territory; do not delay seeking help to research them.

For suspected heatstroke, begin emergency cooling and veterinary contact. Do not assume that moving the dog into air-conditioning alone is enough.

Create a genuinely cool place at home

Dogs need free access to fresh water and a cool area they can move to voluntarily. Outdoors, shade should remain available as the sun moves and should allow air to circulate. A kennel in full sun or a closed, poorly ventilated structure can become dangerously hot.

Indoors:

  1. close blinds against direct sun while maintaining safe ventilation;
  2. use air-conditioning where available;
  3. provide a fan where your dog can choose to move closer or away;
  4. place several stable water bowls in accessible locations; and
  5. check that the coolest retreat remains available while you are out.

Fans support heat loss when used with appropriate cooling, but they do not make a hot closed room safe. Prepare for power outages and heatwaves by identifying another cool location, arranging someone who can check your dog and keeping your vet’s details accessible.

How to cool down a dog safely in hot weather

For a dog that is hot but otherwise bright and responsive:

  • stop exercise and move into shade or a cooler indoor area;
  • offer fresh water without forcing them to drink;
  • wet the body with cool water, avoiding the head and airway;
  • use a fan or create a breeze; and
  • monitor breathing, behaviour and recovery.

A paddling pool can provide optional water play for a healthy, supervised dog that enjoys it. Keep their head and airway safe, use clean water and never force them in.

Do not cover your dog with wet towels, which can restrict evaporative cooling. Frozen treats and cooling accessories may add comfort for some dogs, but they do not prevent heatstroke and are not treatments for overheating.

If panting is relentless, breathing is distressed or your dog shows vomiting, confusion, weakness, staggering or collapse, treat it as heatstroke—not a routine cool-down. Follow the emergency first-aid steps and contact a vet immediately.

Give high-risk dogs a more conservative plan

Any dog can develop heatstroke. Risk can be higher for:

  • flat-faced dogs whose airway makes effective panting harder;
  • puppies and older dogs;
  • dogs carrying excess weight;
  • dogs with heart, respiratory, neurological or other health conditions;
  • dogs with thick coats or limited acclimatisation;
  • dogs exercising, travelling or confined without suitable cooling; and
  • dogs that cannot move away from heat on their own.

Flat-faced dogs need particular caution because breathing difficulty and heat stress can reinforce each other. Noisy breathing at rest, reduced exercise tolerance or a sudden change in breathing warrants veterinary advice even outside summer.

Grooming should suit the coat and the individual dog. Do not shave a double coat as a default heat hack; ask a qualified groomer or your vet what is appropriate. Use only pet-suitable sun protection where your vet recommends it, and prevent ingestion during licking or grooming.

Replace risky exercise with cooler enrichment

Rest does not have to mean boredom. On days when outdoor activity is unsafe, use short, low-impact indoor activities:

  • scatter part of a measured meal in an easy search game;
  • use a puzzle feeder appropriate for your dog’s skill level;
  • practise calm cues and gentle handling;
  • hide a safe toy for a simple indoor search; or
  • rotate a small selection of chew or play activities under supervision.

Avoid turning enrichment into intense activity in a hot room. Count edible rewards within the daily ration and check ingredients against our guide to foods toxic to dogs and cats.

For practical ideas, see Dog Enrichment: The Complete Australian Guide or choose reusable enrichment toys for supervised indoor play.

Add water, travel and summer-event precautions

Not every dog is a confident swimmer. Supervise pools, beaches, rivers and dams; provide a safe exit; prevent drinking large amounts of salt or contaminated water; and rinse off after swimming. Use appropriate safety equipment for boating or deep water.

For car travel, start with a cooled vehicle, maintain ventilation and plan breaks without leaving your dog unattended. Secure your dog safely and keep water accessible when stopped in a safe place.

BBQs and visitors add different risks: cooked bones, skewers, corn cobs, fatty scraps, alcohol, chocolate, grapes and some sugar-free products can all cause harm. Keep bins and leftovers secure, and give guests clear feeding instructions.

Frequently asked questions

Can I walk my dog in 30-degree weather?

There is no universal yes-or-no temperature. Humidity, surface heat, exercise intensity, shade, airflow and your dog’s health all matter. In hot conditions, choose a cooler time, reduce or skip exercise and use indoor enrichment instead. High-risk dogs need more conservative limits.

How do I keep my dog cool without air-conditioning?

Provide shade with airflow, fresh water and access to a cooler part of the home. Use a fan where the dog can move away voluntarily, reduce activity and arrange a backup cool location during extreme heat. These measures do not make every hot environment safe.

Are wet towels good for cooling dogs?

Do not cover a dog with wet towels; they can interfere with evaporation. For routine cooling, wet the body with cool water while avoiding the head and airway, and create a breeze. Suspected heatstroke needs immediate veterinary attention as well as cooling.

Can I give my dog ice in summer?

Ice or frozen food can be an optional treat for some dogs if ingredients and portion sizes are suitable and the dog can consume it safely. It does not replace water, shade or emergency cooling. Avoid forcing items into an overheated or distressed dog’s mouth.

Should I shave my dog to keep them cool?

Not automatically. Coat type, skin, health and grooming needs differ. Shaving a double coat is not a universal solution and may create other problems. Ask your vet or a qualified groomer for individual advice.

Why is my dog panting at night?

Panting can occur with heat, but also pain, stress, medication and illness. Improve the environment and check for other signs. Persistent, unusual or distressed breathing needs veterinary advice; collapse, severe breathing difficulty or other heatstroke signs require urgent care.
