Pug Breathing Problems and Heatstroke: A Bangalore Guide

A pug’s flat face causes its biggest health problem: a narrowed airway that makes breathing, and cooling down, hard work. In UK vet records, pugs had over three times the odds of heatstroke of Labradors (Hall et al., 2020). This guide covers why, the warning signs, the first aid vets now recommend, and how to get a pug safely through Bangalore’s hot months. Share it with anyone else who looks after your pug.

Why pugs struggle in the heat

Pugs are brachycephalic (flat-faced). Their short muzzle squeezes the airway in several places, a set of problems called brachycephalic obstructive airway syndrome (BOAS):

• Narrow nostrils that let in little air
• A long soft palate that hangs into the throat
• Small pouches in the voice box (laryngeal saccules) that can be sucked into the airway
• A narrow windpipe in some dogs

Dogs cool themselves mainly by panting. A pug can’t move enough air to cool down quickly, so its temperature climbs. Across all breeds in that UK study, flat-faced dogs had about twice the odds of heatstroke of dogs with medium-length noses. And the most common trigger was exercise, not hot cars (Hall, Carter and O’Neill, 2020).

Bangalore is milder than most Indian cities: the average April high is about 34°C, and March to May is the hot season (IMD). That is still more than enough to overheat a pug on a walk.

Warning signs

Early signs:

• Loud, laboured panting, louder than your pug’s usual breathing
• Thick, ropy drool
• Bright red tongue and gums
• Lying flat on cool floors, unwilling to move

Act now, this is an emergency:

• Gums or tongue turning blue, purple or pale
• Gagging, choking or wheezing sounds
• Stumbling, weakness or collapse
• Vomiting or diarrhoea
• Seizures, or not responding to you

A dog’s normal temperature is 37.5 to 39.2°C (Merck Veterinary Manual). Above about 41°C is usually heatstroke (VCA).

First aid: cool first, then go to the vet

Current research says the most important thing is to start cooling straight away, and then get to a vet (Hall et al., 2023):

1. Get your pug out of the heat into shade, a cool room or AC.
2. Cool with water. For a young, healthy dog, cold water works best: put the dog in a tub of cold water or under a running tap, keeping its head out. For an older dog or one with other health problems, spray or pour water over the body and point a fan at it.
3. Don’t just drape wet towels over the dog. It’s the most common thing dog parents do, but it isn’t one of the recommended methods.
4. Cool for about 15 minutes before you set off, the time the 2026 RECOVER first aid guidelines for vets suggest when you can’t take your dog’s temperature. Stop sooner if your pug recovers (its breathing settles and it responds normally) or starts to shiver (Dogs Trust): a dog can be cooled too far. With a thermometer, stop at about 39.4 to 40°C (103 to 104°F): VCA stops at 39.4°C, RECOVER at 39.7 to 40°C. In a UK study, 6 of the 14 dogs that reached the vet too cold had been cooled before they arrived (Hall et al., 2023).
5. Offer water to drink if your pug is alert, but don’t force it.
6. Go to the vet, keeping your pug somewhere cool on the way, even if it seems to recover. Heatstroke can damage the kidneys, liver and brain in ways you can’t see.

The old advice to use only room-temperature water, for fear that cold water “shuts down the blood vessels”, isn’t supported by the evidence, and waiting at home to see if things improve wastes the time that matters most.

Daily care in the hot months (March to May)

• Walk only in the coolest hours, early morning and after sunset, and keep walks short and slow. On hot days, skip the walk and play indoors.
• Test the road with the back of your hand: if you can’t hold it there for five seconds, it’s too hot.
• Keep your pug cool indoors in the afternoon, with AC, a fan or a cooling mat, and water in more than one room.
• Never leave a pug in a parked car, even with the windows open.
• Use a harness, not a collar, so nothing presses on the throat.
• Don’t shave a pug. Their coat is short already and shaving exposes the skin to the sun.

Weight matters more for pugs

Extra fat around the throat and chest narrows an airway that is already tight. In a study of pugs, narrow nostrils and a higher body-fat score both predicted breathing problems (Liu et al., 2017).

The breed standard weight for an adult pug is 6.3 to 8.1 kg (Royal Kennel Club). Use the rib, waist and tummy-tuck check in the Labrador weight guide, which works for any breed, along with its weight-loss plan.

Surgery for BOAS

When a pug struggles to breathe even in cool weather, surgery can help a great deal. It usually widens the nostrils, shortens the soft palate and removes the swollen pouches in the voice box, often in one operation. Results are best in young dogs, and poorer once the voice box itself has started to collapse, which is a reason not to wait too long (ACVS).

Talk to your vet about surgery if your pug:

• Breathes noisily even at rest in a cool room
• Sleeps sitting up or with its chin propped up, to breathe
• Can’t manage a short walk without struggling
• Gags, regurgitates or has choking episodes
• Has overheated more than once

We couldn’t find published prices for BOAS surgery in Bangalore; ask your vet for a quote, and ask how many of these operations the surgeon has done.

Other pug problems in the heat and the monsoon

• Skin folds trap sweat and moisture, and yeast grows there. Wipe the folds every day with a damp cloth and dry them well.
• Eyes: pugs’ prominent eyes get dusty and irritated easily. Clean around them gently, and see a vet the same day for a red, cloudy or squinting eye.
• Hot spots: red, itchy patches can appear quickly in humid weather. Check your pug’s skin daily.

FAQs

Why does my pug snore so loudly? Because of the narrow airway. Loud snoring and noisy breathing at rest can be signs of more severe BOAS, so mention them to your vet.

Can my pug have ice or cold water? Yes. A few ice cubes or cool water to drink are fine on a hot day. For cooling an overheated pug, cold water on the body is what the research supports, as above.

Is there a special food for pugs with BOAS? No. Keeping your pug at a healthy weight is what matters. Measure the food, and see the dog food comparison for options.

Which breeds are like pugs but breathe more easily? Any breed with a longer nose. Don’t choose a French Bulldog or English Bulldog for easier breathing: in the UK study they had even higher odds of heatstroke than pugs. A medium-sized indie is about as well suited to Indian weather as a dog gets; see the indie dog guide.
