Pugs and heatstroke: a very real risk, per UK vets
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A Pug panting loudly in only moderate heat isn't overreacting: its brachycephalic build puts it among the breeds most at risk of heatstroke, well before the thresholds that would worry an owner of a longer-nosed dog. Find all our health pointers in the dog care and grooming section.

What a large UK veterinary study shows
A study by Hall, Carter and O'Neill, published in 2020 in Scientific Reports using data from the Royal Veterinary College's VetCompass programme, analysed heatstroke cases among dogs seen in general practice across the UK. Brachycephalic breeds, including the Pug, stood out with a markedly higher-than-average risk, at ambient temperatures most longer-nosed dogs handle without any trouble.
Why Pugs struggle so much to shed heat
- A shortened muzzle, which reduces the surface area normally used for heat exchange through panting in a longer-nosed dog.
- Upper airways that are often already narrowed, limiting airflow even in an individual showing no visible breathing distress at rest.
- Only moderate exertion, a simple brisk walk in warm weather, can be enough to trigger the first signs in this breed, well before what would alarm an owner of a longer-nosed dog.
How to lower the risk day to day
Keeping walks to the cooler hours, avoiding any exertion between 11 am and 5 pm in summer, and offering constant access to water and shade remain the most effective measures. A cooling mat at home is a useful addition during heat spikes. Find the full breed profile on the Pug page and browse all our guides on the dog hub.
Frequently asked questions
At what temperature is a Pug at risk of heatstroke?
The risk rises at only moderate temperatures, well below the thresholds that would trouble a longer-nosed dog, especially with exertion or humidity.
Is loud panting already a warning sign?
Unusually loud or prolonged panting, combined with very red gums or weakness, should prompt immediate cooling and an urgent vet visit.
Can a Pug go on long summer walks?
They're best kept to the cool morning or evening hours, avoiding any sustained exertion during the hottest part of the day.
