Collapsing Trachea in Small Dogs: Signs to Know

Collapsing trachea is a condition where the cartilage rings that normally hold the windpipe open are weaker than they should be, allowing the trachea to partially flatten or collapse, particularly during moments of pressure or excitement. It's seen predominantly in small and toy breeds — Yorkshire Terriers, Pomeranians, Chihuahuas, and Poodles are among the more commonly affected breeds — and tends to worsen gradually with age.

The hallmark sign is a distinctive dry, honking cough, sometimes described as sounding like a goose, often triggered by excitement, pulling against a collar, drinking water, temperature changes, or simply activity. Between episodes, many affected dogs breathe and act completely normal, which can make owners think the cough is an isolated, unrelated event rather than a chronic underlying condition, especially in earlier or milder stages.

As the condition progresses in more severe cases, dogs may show increased effort with breathing generally, reduced exercise tolerance, or episodes that become more frequent and prolonged. Obesity significantly worsens symptoms, since extra weight around the neck and chest area adds pressure on an already compromised airway.

What to do: A small-breed dog with a persistent honking cough, especially one triggered by excitement or collar pressure, is worth a vet visit for evaluation and, if diagnosed, ongoing management — switching to a harness instead of a collar, maintaining a healthy weight, and in some cases medication can meaningfully reduce episode frequency and severity. This condition doesn't go away, but it's very manageable with the right approach once identified.
