This episode explains heatstroke in pets, how it happens, why it can become life-threatening very quickly, and what owners should do if they suspect their dog is overheating. It covers early warning signs, emergency first aid, veterinary treatment, long-term effects, and practical prevention strategies for hot Australian conditions.
Podcast Summary: Understanding Heatstroke in Dogs
- Heatstroke (hyperthermia) occurs when a dog’s body temperature rises faster than it can be cooled.
- Normal dog temperature is around 37.5–38.5°C; serious complications begin above 41°C.
- Dogs cool themselves primarily through panting, they do not sweat like humans.
- High humidity significantly reduces a dog’s ability to cool down, even at moderate temperatures.
- Intense exercise can trigger heatstroke in as little as five minutes under humid conditions.
- Early signs include heavy panting, distressed breathing, bright red gums, and restlessness.
- As heatstroke progresses, dogs may develop weakness, wobbliness, collapse, seizures, or coma.
- Heatstroke can look similar to tick paralysis or snake bite, making veterinary assessment important.
- Immediate first aid includes wetting the dog, using cool packs (not directly on skin), air conditioning, and urgent transport to a vet.
- Do not force water into the mouth if the dog is distressed or semi-conscious.
- Veterinary treatment includes active cooling, oxygen, sedation, intravenous fluids, and monitoring for organ damage.
- Complications can include brain swelling, kidney damage, blood clotting disorders (DIC), and internal bleeding.
- Some dogs that survive heatstroke may be more sensitive to heat in the future.
- Prevention includes avoiding exercise in heat and humidity, ensuring shade and water, and recognising high-risk breeds.
- Brachycephalic (flat-faced) breeds and overweight dogs are at significantly higher risk.
- Starting walks with a pre-cooling hose-down can help, but avoiding exercise in risky conditions is safest.
