Dog breeds most vulnerable to heatstroke as summer temperatures rise

Veterinarians in the United Kingdom and India warn that rising summer temperatures put many dogs at risk of heatstroke. Brachycephalic breeds such as pugs, bulldogs, boxers, Boston terriers and Shih Tzus are especially vulnerable because their short, flat faces hinder breathing. Dogs with thick double coats—including Chow Chows, Golden Retrievers, Huskies and German Shepherds—along with Greyhounds, senior dogs, overweight dogs and puppies also face heightened danger.

Early warning signs include excessive panting, drooling, rapid breathing, restlessness, bright red or darkened gums, weakness, agitation, staggering, vomiting and diarrhoea. If these symptoms appear, owners should move the animal to a cool, well‑ventilated area, apply room‑temperature water to the paws, belly and neck, offer small amounts of water if the dog is conscious, and use a fan for airflow. Ice‑cold water or ice baths should be avoided as they can constrict blood vessels. Veterinary attention must be sought immediately because heatstroke can cause rapid organ failure.

Pet owners are advised to keep dogs out of direct sun during peak heat, provide shade and fresh water, avoid strenuous exercise and hot car rides, and ensure indoor pets stay in cool rooms with proper ventilation. Simple measures such as closing curtains, using fans, and limiting exposure during the hottest part of the day can substantially reduce the risk of overheating.
