Quick Answer

Summer in Auckland can pose serious risks to your dog. Dogs are more vulnerable to heat than we are - here are essential tips to keep your dog safe.

Never Leave Your Dog in a Hot Car

One of the biggest dangers to dogs in hot weather is being left alone in a car. Even if you crack the window, the temperature inside a parked car can quickly become lethal. On a 21C day, the interior of a car can heat up to 37C within 30 minutes.

Dogs can suffer from heatstroke within minutes, which can lead to organ failure or even death. If you're planning to go out, leave your dog at home in a cool space with plenty of shelter and water.

Be Mindful of Hot Footpaths, Roads and Sand

Hot surfaces like asphalt and concrete can burn your dog's paws, even on cloudy or windy days. If it's too hot for you to walk barefoot, it's definitely too hot for your dog's paws.

Quick test: Place the back of your hand on the pavement for a few seconds - if it's too hot for your hand, it's too hot for your dog's paws.

Walk your dog during the cooler parts of the day (early morning or late evening) when the ground has had time to cool off.

Watch Out for Overheating and Hyperthermia

Dogs don't sweat like humans do. Instead, they primarily regulate their body temperature by panting, which is not always sufficient in extremely hot conditions.

Early signs your dog may be overheating include:

  • Heavy panting
  • Drooling
  • Excessive thirst
  • Vomiting
  • Lethargy
  • Disorientation

Signs of heatstroke in dogs include:

  • Excessive panting or drooling
  • Rapid or difficulty breathing
  • Weakness or lethargy
  • Bright red or pale gums
  • Uncoordinated movements or collapse

If you notice these signs, immediately move your dog to a cooler area, offer water, and dampen their body with cool (not cold) water. Never use ice. Take your dog to a vet immediately.

Apply Dog-Specific Sunscreen

Yes, dogs can get sunburned too! Breeds with thin coats or light-colored fur are especially susceptible. Look for sunscreen made specifically for dogs (do not use human sunscreen). In the harsh NZ sun, it's best to keep your dog out of direct sun between 10am-4pm.

Keep Them Cool with Shade and Water

Dogs need access to shade and plenty of fresh water to stay hydrated. At home, you can set up a kiddie pool so your dog can cool off by splashing around.

Adjust Activity Levels

Opt for short, slow walks during cooler hours (early morning or late evening). Engage your dog in indoor activities like puzzle toys or short training sessions to burn energy without overheating.
