Pomeranian: tracheal collapse and why a harness beats a collar
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A Pomeranian that coughs repeatedly, especially when excited or after pulling on the leash, may be dealing with a respiratory vulnerability its breed is statistically more exposed to than the average dog. Find all our accessory guidance in the dog accessories section.

What the recent study shows
A study by Kim, Kim, Ryu, Youn, Choi and Seo, published in 2024 in Frontiers in Veterinary Science, analysed 110 cases of tracheal collapse in small-breed dogs diagnosed by fluoroscopic examination (see the study). The Pomeranian ranks among the most represented breeds in this cohort, alongside the Yorkshire Terrier, Poodle and Chihuahua, with most affected dogs over eight years old at diagnosis.
Why a harness protects the trachea better
- Pressure spread across the chest rather than concentrated on the neck, limiting the sudden jolts that transmit directly to an already fragile trachea in this breed.
- A well-fitted no-pull harness, which reduces the sharp tugging responsible for coughing fits in a small dog prone to collapse.
- A collar kept for ID tags only, never used as the main leash attachment point for an at-risk Pomeranian.
Spotting the signs and adjusting daily habits
A dry, honking cough, breathlessness after exercise or excitement in an adult Pomeranian should prompt a vet visit. Maintaining an optimal weight also eases pressure on the airways. Our guide to the no-pull front-clip harness covers the key criteria for small breeds. Find the full breed profile on the Pomeranian page and browse all our guides on the dog hub.
Frequently asked questions
Does tracheal collapse only affect the Pomeranian?
No, it mainly affects small breeds, but the Pomeranian is among the most represented breeds in recent studies on the condition.
Is a harness enough to prevent collapse?
It reduces mechanical strain on the trachea but doesn't prevent an existing predisposition; veterinary follow-up remains necessary with persistent coughing.
Does tracheal collapse worsen with age?
Yes, the study confirms a higher prevalence in older dogs, which is why vigilance should increase as the dog ages.
