Is Lemon Juice a Safe Fix for Heat Stroke in Dogs?

Every summer, the same well-meaning but dangerous advice starts doing the rounds—“Give a dog lemon juice if they’re overheating, it clears the airway and breaks down mucus.” Unfortunately, this is not only untrue but also potentially harmful.
As dog professionals, we often hear these kinds of tips passed along in parks or online. While they may sound like harmless home remedies, myths like these can delay proper treatment and make a serious situation even worse.
Why Lemon Juice Isn’t a Safe Remedy
There’s no scientific evidence to support the idea that lemon juice helps dogs recover from heat stroke. In fact, citrus juice can irritate a dog’s stomach and mouth, especially when they’re already in distress. Lemon juice won’t lower a dog’s body temperature, restore hydration effectively, or reverse the internal effects of overheating.
More worryingly, trying to force lemon juice into a dog’s mouth when they’re weak, disoriented, or even unconscious is dangerous. It can lead to choking or aspiration, which only adds to the emergency.
What Heat Stroke in Dogs Really Needs
Heat stroke is a medical emergency. It can happen quickly and becomes life-threatening in minutes. Signs to look for include:
Rapid panting or difficulty breathing
Drooling, vomiting, or diarrhoea
Lethargy, confusion, or collapse
Bright red or tongue
Very high body temperature (over 40°C)
If you suspect a dog is suffering from heat stroke, here’s what to do instead:
-Move them to a cool, shaded area straight away. Avoid direct sun and keep them calm.
-Offer small amounts of cool water to drink. Don’t pour water over their head or force them to drink.
-Use cool, damp towels on their belly area. Focus on the stomach, under the armpits, and groin area. Never over the head or body. You can also use a fan or AC to help evaporation, which aids cooling.
-Immurse them in cool water. Pop them in water up to their chest. No, this will not put them into shock as old advice suggests.
-Contact a vet immediately. Even if the dog seems to be improving, internal damage from heat stroke isn’t always visible.
