Tracheal collapse is a progressive airway disease where the windpipe becomes weak and flattens during breathing.

 

It is most common in small/toy-breed dogs such as Yorkshire Terriers, Pomeranians, Chihuahuas, Toy Poodles, and Maltese.

 

Many dogs are managed medically, but dogs with severe respiratory distress, repeated crises, or poor quality of life may benefit from tracheal stenting. Stents can provide rapid airway opening, but they are not a cure and most dogs still need lifelong cough and airway management.
