Emergency — phone the vet now Immediate

Dog struggling to breathe

Difficulty breathing in a dog is always an emergency — phone the vet now and head straight to the practice; do not delay for showers, food, or other tasks.

Dog

Recognise the signs

Open-mouth breathing at rest (always abnormal at rest in dogs except after exercise)
Increased breathing rate at rest (over 35 breaths per minute)
Flared nostrils, neck stretched out
Standing with elbows out, reluctant to lie down
Noisy breathing — wheezing, raspy, snoring sounds
Blue, grey, or very pale gums
Distress and panic
Coughing, often with white or pink froth

First aid steps

Phone the emergency vet immediately and describe what you see.
Keep the dog calm and minimise movement — carry small dogs to the car, walk large dogs slowly on a loose lead.
Cool the dog if heat may be a factor.
Remove any tight collar.
Drive smoothly and do not let the dog get worked up.

Do NOT

Do not muzzle a dog struggling to breathe — they need every airway centimetre.
Do not assume snoring noises are just 'how Bulldogs breathe' — sudden worsening is an emergency.
Do not give food or water.
Do not delay to take photos or finish what you were doing.
Do not give human cough or asthma medication.

While transporting to the vet

Keep car cool — open windows or aircon.
Allow the dog to choose its position; many prefer to sit upright with elbows out.
Phone ahead — oxygen, IV fluids and X-ray will be prepared.
Have a passenger sit with the dog if possible to keep them calm.

When to phone the vet immediately

Any difficulty breathing at rest is an emergency
Blue, grey, or very pale gums
Collapse
Open-mouth breathing in a dog that is not just panting from exercise
Choking gestures or pawing at the throat (see dog-choking)

Common causes

Heart failure with fluid in lungs
Pneumonia
Foreign body in throat or airway
Brachycephalic obstructive airway syndrome (BOAS) collapse — Bulldogs, Pugs, French Bulldogs
Laryngeal paralysis (older Labradors, Golden Retrievers)
Heat stroke
Allergic reaction or anaphylaxis
Trauma — pneumothorax, diaphragmatic hernia after RTA
Tumour pressing on airway
Severe anaemia

What the vet will need to know

How long the dog has had breathing difficulty
Recent activity, heat exposure, or trauma
Cough — frequency, productive or not
Known heart, airway, or laryngeal conditions
Current medications
Breathing rate (count chest rises in 30 seconds and double)
Gum colour

Aftercare

Initial stabilisation usually involves oxygen and rapid diagnostics (X-ray, ultrasound, bloods).
Treatment depends on cause — diuretics for heart failure, antibiotics for pneumonia, surgery for foreign bodies or BOAS, etc.
Hospitalisation often 24–72 hours.
Long-term plan addresses underlying disease — heart medication, weight management, BOAS surgery.

Prevention

Keep brachycephalic breeds lean — obesity worsens BOAS dramatically.
Avoid exercising flat-faced breeds in heat or humidity.
Address known heart disease promptly with regular checks and medication compliance.
Microchip and ID tag — breathing collapse on a walk is a recognised cause of lost dogs.
Take BOAS surgery seriously when recommended — it is genuinely life-extending.

Breed-specific notes

BOAS: Bulldog, French Bulldog, Pug, Boxer, Boston Terrier, Cavalier King Charles Spaniel.
Heart failure: Cavalier, Doberman, Boxer, large/giant breeds.
Laryngeal paralysis: older Labradors, Golden Retrievers, Saint Bernards.

Frequently asked questions

What's a normal breathing rate for a resting dog?

Roughly 10–30 breaths per minute at rest, with 15–25 typical for most adult dogs. Counting your dog's resting respiratory rate while asleep on a normal day gives you a personal baseline; numbers consistently above 35 at rest are a strong sign of heart or lung trouble.

Is heavy panting always concerning?

Not always — panting after exercise, in heat, or from excitement is normal. Panting at rest in a cool environment, especially with elbows-out posture, pale gums, or noisy breathing, is concerning and warrants vet contact.

My Bulldog has always breathed loudly — when is it suddenly an emergency?

Any worsening from baseline — louder noise, more effort, blue tongue, collapse, refusal to lie down — is an emergency in a brachycephalic breed. BOAS dogs sit much closer to airway collapse than non-brachycephalic dogs and decompensate quickly in heat or stress.
