Pet Heatstroke Warning Signs

Prevent overheating

• ●Never leave a pet in a parked vehicle — interiors heat dangerously fast, even with windows cracked.
• ●Provide constant access to shade and fresh water in warm weather.
• ●Avoid exercise during the hottest part of the day; choose early morning or evening.
• ●Be extra cautious with flat-faced (brachycephalic) breeds, older pets, overweight pets, and those with heart or breathing conditions.
• ●Check that pavement or sand is not too hot before walking your pet on it.

Possible signs of heat-related illness

These signs can have many causes, and not every pet shows every sign. If you suspect overheating, treat it as urgent — move the pet to a cooler place and contact a veterinarian immediately.

• ⚠Heavy, frantic, or persistent panting.
• ⚠Excessive drooling or very red gums and tongue.
• ⚠Weakness, stumbling, or reluctance to move.
• ⚠Vomiting or diarrhoea.
• ⚠Disorientation, collapse, or seizures.

When to contact a veterinarian or emergency clinic

Suspected heatstroke is an emergency. Do not try to diagnose from this page.

• →Move the pet out of the heat to a cooler, shaded, or air-conditioned area straight away.
• →Contact a licensed veterinarian or emergency clinic immediately and follow their instructions, including any cooling steps they direct.
• →Offer small amounts of cool water if the pet is alert and able to drink, but do not force it.
• →Go to the nearest clinic without delay if the pet is collapsed, disoriented, seizing, or struggling to breathe.

What not to do

• ✕Do not use ice-cold water or ice baths, which can be harmful — follow veterinary guidance on cooling.
• ✕Do not assume a pet has "cooled down and is fine" — heat illness can worsen internally even after panting eases.
• ✕Do not delay veterinary contact while trying to manage it at home.
• ✕Do not leave any pet in a parked car, even briefly.
