Would you recognise heatstroke in your pet? And more importantly, would you know how to help them if they were to develop this potentially life-threatening condition?

Here’s the lowdown on heat-related illness in pets, including symptoms to watch for and the treatment required.

What is heatstroke?

Heatstroke is the most severe stage in a spectrum of heat-related illnesses that can develop rapidly when your pet’s ability to cool itself becomes overwhelmed, so that their internal body temperature rises beyond tolerable levels.

Body temperatures above 41 degrees Celsius can cause damage to the cells of your pet’s body, potentially affecting their brain, heart, kidneys, gastrointestinal system, and blood clotting.

What are the symptoms of heatstroke?

Pets with mild to moderate heat-related illness (often referred to as heat stress or heat exhaustion) will show symptoms such as tiredness, increased thirst, and heavy panting, but will still be mentally aware. As the pet becomes more seriously affected, they may start to develop additional symptoms, including:

• Weakness or wobbliness
• Confusion or reduced consciousness
• Abnormal gum colour (e.g. dark red or purplish gums, or pale gums)
• Heavy drooling
• Vomiting or diarrhoea, which may contain blood
• Muscle tremors or seizures

What should you do if your pet shows signs of heat-related illness?

Pets showing signs of heat stress or heat exhaustion should be immediately placed in a cool area to rest, such as in front of a fan or in air conditioning. These pets should be kept well-hydrated and monitored closely for any other signs of unwellness.

However, if your pet is showing any of the more severe symptoms of heatstroke, it’s strongly recommended to:

• Wet them from the neck down in cool (but not ice-cold) water
• If they seem sufficiently aware and can hold their head up, offer them some water to drink
• Seek immediate veterinary attention, transporting your pet in a cool air-conditioned vehicle (or at least with the windows open)
