Animal Friends Pet Insurance warns of dog heatstroke risk from 20 °C during UK heatwave

A 38 °C heatwave triggered a rare red extreme‑heat warning across parts of the United Kingdom, prompting school closures and transport disruptions. In response, Animal Friends Pet Insurance issued new guidance on canine heatstroke risk. The insurer says the danger begins at temperatures as low as 20 °C, especially for exercising dogs, and escalates sharply above 24 °C, becoming life‑threatening at 32 °C.

Temperatures between 7 °C and 15 °C are generally safe for all breeds. Between 16 °C and 19 °C owners should monitor vulnerable dogs such as flat‑faced, overweight or older pets. From 20 °C to 23 °C all dogs face heatstroke risk, and above 24 °C conditions are deemed very dangerous. The guidance advises walking dogs before 8 am, using shaded routes, carrying water and shortening walks. Jen Wormleighton, Head of Veterinary Services at Animal Friends, said: “Many owners see dog walking as part of a healthy daily routine, but in warmer weather it’s important to adapt that routine to keep pets safe.” The RSPCA notes dogs rely on panting to cool and can suffer fatal heatstroke quickly if exposed to high temperatures.
