How Hot Is Too Hot? The Danger of Hot Cars for Dogs
Cars can become deadly for dogs in minutes, even on mild days. There is no safe outside temperature to leave a dog unattended in a car. Vehicles act like greenhouses and heat up fast, and cracked windows do not stop this. Around 20°C outside can already be risky and 22 to 24°C can quickly become life threatening inside a car. Flat faced breeds such as Bulldogs, Pugs, French Bulldogs and Boxers, plus puppies, older dogs, overweight or thick coated dogs and those with heart or breathing problems are at higher risk. Early signs of overheating are heavy panting, drooling, restlessness and bright red gums. Later signs include vomiting, collapse, seizures and loss of consciousness. If a dog is overheating move it to a cool place, give small sips of cool water, wet their body with cool water, increase airflow and call a vet; do not use ice cold water. Never leave a dog alone in a warm car. If the weather feels warm to you it is probably too warm for a dog. Leaving a dog in a hot car can cause severe suffering and may lead to fines or prosecution.
