Unlike us, dogs don’t sweat. They can only really reduce their body temperature by panting, so it's not uncommon during sweltering Australian summers for dogs to suffer from heat stress and heatstroke. Heat stress occurs when a dog’s body temperature rises significantly and it can’t cool itself down fast enough, resulting in excessive and rapid panting, and noticeable agitation. Heatstroke occurs when the heat stress isn’t corrected fast enough and the dog's body temperature continues to rise. The result can range from simple lethargy to seizures, multiple organ failure, and even death.
