Heatstroke In Pets: What Every Owner Should Know

When summer heats up in New Zealand, our furry family members feel it too. Heatstroke in pets is a serious and potentially life-threatening condition most common during the warmer months. Knowing the signs and how to respond can make all the difference. Whether you have a playful puppy, a curious kitty, or a golden oldie who loves the sun, we've got the facts and tips to help keep them safe — because at Petdirect, We Get Pet.

What Is Heatstroke In Pets?

Heatstroke occurs when a pet's body temperature rises to dangerous levels, typically over 39.5°C. Unlike humans, pets can’t sweat to cool down. Dogs mainly regulate heat through panting and limited sweat glands in their paws, while cats do so quietly through grooming and resting. When this natural cooling system isn’t enough — for example, on a humid day or in a hot car — their body temperature can rise rapidly to dangerous levels.

In New Zealand, our mild climate can still pack a punch in summer, especially for brachycephalic breeds (like Pugs, Bulldogs or Persian cats), older pets, or those with health conditions.

Spotting The Signs Of Heatstroke

Catching the early signs of overheating can save your pet's life. Watch for:

• Excessive panting or drooling
• Red gums and tongue
• Weakness, wobbliness or collapse
• Vomiting or diarrhoea
• Confusion or seeming dazed

In cats, symptoms can be more subtle — open mouth breathing, restlessness, or rapid heartbeat could be signs. Any of these symptoms require immediate action.

What To Do If You Suspect Heatstroke

If you think your pet has heatstroke, act fast:

• Move them to a cool, shaded area
• Offer small amounts of cool (not cold) water
• Wet them with lukewarm water or damp towels, especially on the paws and belly
• Avoid ice or shockingly cold water — this can make things worse
• Contact your vet immediately

Even if your pet seems to be recovering, it's best to get a professional check — heatstroke can affect organs long after symptoms ease.

How To Prevent Heatstroke

Prevention is the best protection, and it all comes down to a bit of summertime planning:

• Fresh water: Ensure pets have constant access to clean, cool water. A pet water fountain can encourage drinking on hot days.
• Shade and airflow: Provide shaded resting spots and avoid leaving pets in confined or poorly ventilated areas.
• Exercise timing: Walk dogs early in the morning or later in the evening when it’s cooler.
• Never leave pets in cars: Even with windows cracked, temperatures soar alarmingly fast.
• Cooling products: Explore cooling essentials like cooling mats or vests designed to keep pets comfortable on hot days.

Best Products To Keep Pets Cool And Safe

Whether you have a cat that sunbathes by the window or a dog who loves the beach, a few smart choices can make heat safety a breeze:

• Hydration support products help encourage water intake throughout the day
• Calming products can help anxious pets settle during hot, restless weather
• Cooling gear and summer toys add fun and functionality during playtime
• Supplements that support skin, coat and general wellness during seasonal stress

For pets particularly prone to overheating, such as breeds like the French Bulldog or the Ragdoll cat, extra care and gear can go a long way.
