The Frenchie Breathing Guide: What's Normal, What's Not, and How to Help
Snorts, snores and grunts are part of life with a Frenchie. But "common" and "healthy" aren't the same thing, and knowing the difference can save your dog's life.
Why Frenchies struggle to breathe
Frenchies have a short, flat face, but the same amount of soft tissue inside as a longer-nosed dog. That tissue gets squeezed into less space. Vets call the result BOAS (Brachycephalic Obstructive Airway Syndrome). It can include:
- Narrow nostrils (like breathing through a pinched straw)
- A long soft palate that flaps into the airway
- A narrow windpipe and swollen tissue in the throat
The numbers are striking:
- Compared with other dogs, Frenchies have about 42 times the odds of narrow nostrils and 31 times the odds of BOAS (O'Neill et al., 2021).
- In a 2025 survey of 574 Frenchie owners, 35% reported narrow nostrils and 26% an elongated soft palate. Dogs with shorter noses had more snoring, heat intolerance and breathing episodes (German survey, 2025).
- French Bulldogs are one of the breeds most at risk of heatstroke (Hall et al., 2020).
Normal vs not normal
Usually OK - Soft snoring while asleep - A little snorting when excited - An occasional reverse sneeze (a loud, honking inhale that stops on its own)
Talk to your vet - Loud breathing even when resting - Snoring that wakes them up, or sleeping sitting up or with a toy in the mouth (to hold the airway open) - Tiring after a few minutes of walking - Gagging, coughing or bringing food back up after meals - Blue-ish tongue during exercise
Emergency, go now - Heavy panting that won't settle in a cool, quiet place - Blue, grey or very pale gums - Wobbling, collapse or confusion - Vomiting during a hot day
The breathing check you can record for your vet
Breathing problems often look different at home than at the vet. Record this:
- Sleeping breathing rate: while your Frenchie is fast asleep, count breaths (each rise of the chest) for 30 seconds and double it. Under about 30 per minute is typical for a resting dog. Do it on 3 different nights.
- A 30-second video at rest with the sound on.
- A 30-second video after a 5-minute walk on a cool day.
- A video of any "episode" like gagging or reverse sneezing.
Your vet can use these to judge how much your dog is struggling, and whether surgery to open the nostrils or shorten the soft palate might help.
5 everyday habits that make breathing easier
1. Harness, never a collar
A collar presses on the windpipe every time they pull. A well-fitted harness takes that pressure off.
2. Let the weather set the schedule
Walk early in the morning or late in the evening on warm days. Keep it short, stay near shade and carry water. Humidity makes it worse. If it's warm for you, it's dangerous for them.
3. Keep them lean
Fat around the neck and chest narrows the airway even more. Aim for ribs you can feel easily and a visible waist from above. Weight is one of the few BOAS factors you fully control.
4. Cool, calm living
Air conditioning or fans in summer, cooling mats, and never leave a Frenchie in a car. Avoid letting them get worked up in hot weather. Excitement makes them breathe harder too.
5. Calm mealtimes
Small meals, a shallow slow feeder, and quiet time afterwards reduce gagging and regurgitation (see the Frenchie tummy guide).
By age
- Puppies: ask your vet to check the nostrils and soft palate at the first visits. Early surgery can make a big difference for dogs with severe narrowing.
- Adults: keep a log of sleeping breathing rate once a month. Rising numbers are worth a call.
- Seniors: heat tolerance drops with age. Shorten summer walks and watch weight closely.
