Emergency — come in immediately

Difficulty breathing
in dogs

Any dog breathing with obvious effort, showing blue or gray gums, or struggling to get air in is experiencing a respiratory emergency. Come in immediately — do not wait to see if it improves.

When breathing is an emergency

Dogs breathe without obvious effort when healthy. Normal breathing at rest is quiet, regular, and uses minimal muscle work. Any visible departure from this — especially if accompanied by the signs below — is a reason to seek emergency care without delay.

Come in immediately if your dog shows any of these
  • Blue, purple, or gray gums or tongue — oxygen deprivation
  • Open-mouth breathing at rest — dogs should not pant without exertion
  • Elbows flared out from body, neck extended — working hard to breathe
  • Breathing that is noisy, wheezing, or wet-sounding
  • Choking, gagging, or pawing at the mouth — possible airway obstruction
  • A flat-faced dog (Bulldog, Pug, Frenchie) whose breathing sounds worse than usual and who is distressed or lethargic
  • Rapid breathing rate at rest (more than 40 breaths per minute)

Common causes of respiratory emergencies in dogs

Laryngeal paralysis

The larynx controls airflow into the trachea. In laryngeal paralysis, the cartilage flaps that open during inhalation become paralyzed and collapse inward, partially blocking the airway. Most common in older large-breed dogs — particularly Labrador Retrievers. Signs include a loud, raspy breathing sound (especially on inhalation), voice change, exercise intolerance, and in severe cases, complete airway obstruction. Heat and excitement dramatically worsen symptoms.

Congestive heart failure with pulmonary edema

When the heart fails to pump efficiently, fluid backs up into the lungs. Dogs develop rapid, labored breathing, often with a wet or bubbly quality to the breath sounds. They may be reluctant to lie down (orthopnea). Emergency diuretic therapy and oxygen can be dramatically effective — a dog in respiratory distress from pulmonary edema often shows significant improvement within 30 to 60 minutes of treatment.

Tracheal collapse

Common in small breeds, tracheal collapse causes a characteristic honking cough and varying degrees of respiratory distress. Mild cases are managed medically; severe cases may require referral for tracheal stenting or other interventions.

Foreign body airway obstruction

A dog choking on a ball, bone fragment, or other object may paw at the mouth, make gagging sounds, or become suddenly unable to breathe. This is a true life-threatening emergency. Do not attempt finger sweeps unless you can clearly see and grasp the object. Come in immediately.

What we do when a dog in respiratory distress arrives

We minimize stress and maximize oxygen immediately. Most respiratory patients go straight into an oxygen cage on arrival while a brief triage assessment is performed. Once partially stabilized, we perform a chest X-ray to identify the cause. Treatment — diuretics, bronchodilators, oxygen, or other interventions — is started based on what we find. In some cases, a sedative is used to reduce the patient's own oxygen demand while we work to correct the underlying problem.

Frequently asked questions

Signs of labored breathing in dogs include: breathing with visible effort — the sides heaving, the belly pumping, or the chest working harder than normal; elbows held away from the body to allow the chest to expand; neck extended forward; breathing with an open mouth at rest (dogs normally only pant after exertion); breathing that is noisy, wheezy, or wet-sounding; rapid breathing at rest; and blue, gray, or purple gums or tongue, which indicates inadequate oxygen. Any of these signs warrant immediate emergency evaluation.
Common causes include laryngeal paralysis (loss of function of the larynx, common in older large-breed dogs), tracheal collapse (common in small breeds like Yorkies and Chihuahuas), congestive heart failure with pulmonary edema, pneumonia, pleural effusion (fluid around the lungs), pulmonary thromboembolism (blood clot in the lungs), airway foreign body obstruction, and brachycephalic obstructive airway syndrome in flat-faced breeds (English Bulldogs, Pugs, French Bulldogs).
A honking or goose-like cough in small dogs is often tracheal collapse — a condition where the cartilage rings of the trachea lose their rigidity and the airway narrows or collapses during breathing. Excitement, exercise, and heat can trigger or worsen episodes. While mild cases can be managed with medications, severe episodes — particularly if the dog's gums turn blue or they cannot catch their breath — are emergencies.
Yes. Brachycephalic breeds — English Bulldogs, French Bulldogs, Pugs, Boston Terriers, Boxers, Shih Tzus, and Persian cats — have anatomical features that restrict airflow: narrowed nostrils, an elongated soft palate, and a narrowed trachea. These dogs struggle with heat, exercise, and stress more than other breeds, and are at higher risk for acute respiratory crises. In hot Texas summers, brachycephalic dogs are particularly vulnerable to heat-related respiratory distress.
Pulmonary edema is fluid in the lung tissue itself — not in the chest space around the lungs. It most commonly occurs as a complication of congestive heart failure, where the heart cannot pump efficiently and pressure backs up into the lungs. Treatment involves diuretics (medications that remove excess fluid, most commonly furosemide), oxygen supplementation, rest, and treatment of the underlying heart condition. Dogs with pulmonary edema from heart failure often require emergency stabilization and may need long-term cardiac medications.
