“Honk honk”. Once you’ve heard a pet demonstrating a classic “tracheal collapse cough”, you’ll never forget it!

On that note, here’s a little blast of information about tracheal collapse, including which dog breeds are more at risk, how it’s diagnosed, and how we can help.

What is tracheal collapse?

Tracheal collapse is a degenerative condition where the cartilage rings of the trachea (the windpipe) become weak. This means that during periods of increased airway pressure, the airway will briefly flatten or collapse – kind of like when you suck hard on a weak, soggy straw!

These episodes of airway collapse often happen during exercise, during hot or humid weather, or when the pet is excited or pulling at their collar. Some dogs may also show symptoms after they eat or drink.

Which dogs are most at risk of tracheal collapse?

Tracheal collapse most commonly affects middle-aged to senior pets, particularly toy breeds such as Toy Poodles, Pomeranians, Chihuahuas and Shih Tzus.

How is tracheal collapse diagnosed?

Tracheal collapse is often suspected based on a history of an intermittent cough (which may sound like a “goose honk”), particularly if it occurs during periods of increased activity and is affecting a small breed dog.

However, further diagnostic tests may be recommended to help rule out other conditions that can also cause a persistent cough (such as heart disease or chronic bronchitis) and confirm the diagnosis. These include chest x-rays, and sometimes more specialist airway imaging, such as fluoroscopy (real-time, moving x-rays to document the brief episodes of airway collapse) or endoscopy (examining inside the airways with a tiny camera).

Can tracheal collapse be treated?

Many pets with tracheal collapse can be managed with lifestyle adjustments (such as being walked with a harness, and not being exercised in warm weather) and medical therapy, which may include:

• Cough suppressants
• Airway-relaxing medications
• Steroids
• Antibiotics
• Weight loss for overweight pets

However, more severely affected pets may require referral for specialist surgery.
