What is heatstroke?
Heatstroke or hyperthermia is when body temperature starts to rise above normal (38.6C/101.5F). If your dog’s temperature stays too high for too long, their organs will start to fail and they may die.
Unlike us, dogs can’t sweat to lose body heat, they can only pant. Overweight dogs, flat faced breeds (e.g. Pug) and dogs with thick coats are more at risk of heatstroke.
Being left or trapped in a small, hot space or over-exercising on a hot day are two of the most common causes of heatstroke.
