Collapsed Trachea in Dogs: The Honking Cough and What Helps

What it usually means

The trachea, or windpipe, is held open by C-shaped rings of cartilage joined by a thin muscle membrane. In tracheal collapse, VCA explains, the rings weaken or the membrane sags, so the airway flattens and narrows, most noticeably when the dog breathes in or coughs. Narrowing irritates the lining, which causes more coughing, which irritates it further, a cycle that can make the cough hard to settle.

VCA reports it is most often seen in dogs about 4 to 14 years old, and that Chihuahuas, Pomeranians, Shih Tzus, Lhasa Apsos, Toy Poodles and Yorkshire Terriers are commonly affected, likely for genetic reasons. The AKC notes that obesity, heart disease, airway irritants and other lung problems make signs worse. The condition is progressive, meaning it tends to get gradually worse over the years.

Signs and common triggers

The hallmark is a harsh, dry cough that sounds like a goose honk, often in fits lasting several minutes and sometimes ending in a gag or retch. Unlike kennel cough, there is usually no fever, sneezing or nasal discharge. Other signs include noisy breathing, wheezing, tiring quickly on walks, and in more severe cases fast breathing or difficulty catching breath.

Coughing is commonly triggered by excitement, such as greeting visitors, pulling against a collar, eating or drinking, hot or humid weather, exercise, stress, and smoke or other irritants, and is often worse at night. Recording a coughing fit on your phone is very useful, because many dogs will not cough in the exam room. Heart disease can cause a similar cough and the two can occur together, so a vet exam is important.

When to call your vet today

Book a visit if your small dog has a honking cough that keeps coming back, coughs when you pick up the leash or touch its neck, tires easily, or snores or breathes noisily when it did not before. Early management can slow how quickly signs progress and keep your dog more comfortable.

Call sooner if a dog already diagnosed starts coughing more often, coughs through the night, seems tired, eats less, or has a cough that becomes wet or comes with a fever, which can suggest a chest infection on top of the collapse.

When it's an emergency

Go to your vet or the nearest emergency vet immediately if your dog is struggling to breathe, breathing very fast or with its mouth open at rest, has blue, gray or very pale gums or tongue, faints or collapses, or cannot stop coughing. The AKC describes breathing difficulty in these dogs as a medical emergency.

On the way, keep your dog as calm and cool as possible, remove its collar, avoid holding it tightly against your chest, and keep car windows or the air conditioning on in warm weather. Call ahead so the team can have oxygen ready. Do not give any human cough medicine.

What you can safely do at home

Switch to a harness for every walk and never lead a dog with tracheal collapse by the neck. Keep your dog at a lean, healthy weight, as extra fat around the chest and neck increases pressure on the airway. Avoid walks in heat and humidity, keep exercise gentle and steady, and calm greetings at the door to limit excitement.

Keep your home free of cigarette smoke, scented sprays, candles and dusty products. Some dogs cough less when eating from a raised bowl or when meals are split into smaller portions. Do not give human cough syrups or cold remedies, which can contain ingredients that are dangerous to dogs.

What the vet will likely check

Your vet will listen to the chest and heart, watch your dog breathe, and may press gently on the windpipe, since VCA notes that light pressure causing a cough raises suspicion. Diagnosis is confirmed with X-rays, fluoroscopy, which is a moving X-ray that shows the airway collapsing in real time, or a camera exam of the airway under anesthesia. Heart disease, lung disease and infection are ruled out at the same time.

Most dogs are managed medically, with weight control and medicine your vet chooses to ease coughing, reduce airway inflammation, open the airways or treat infection. VCA notes that liver function may be monitored, as these dogs often have liver changes too. Dogs whose breathing does not improve with medical care may be offered surgery, such as a stent placed inside the windpipe or rings placed outside it, usually by a specialist. Most dogs still cough somewhat after treatment.

Prevention and long-term care

There is no known way to prevent tracheal collapse, but you can reduce how often it flares. The AKC's management advice centers on weight control, treating any heart or lung disease, using a harness instead of a collar, avoiding smoke and heat, and adjusting exercise to what your dog can comfortably do.

Keep regular checkups so your vet can track progress, and note the frequency of coughing fits in a diary or app. Know the emergency signs and where your nearest emergency vet is, especially in summer.
