Collapsed Trachea in Pets: Causes, Treatment, and the Role of Diet
What Is Tracheal Collapse? Tracheal collapse is a progressive respiratory condition where the windpipe (trachea) loses its structural rigidity and partially flattens during breathing. The trachea is normally supported by C- shaped cartilage rings that keep the airway open. When these weaken, the airway narrows, making breathing difficult. This condition is most commonly seen in small breed dogs (e.g., Yorkshire Terriers, Pomeranians, Chihuahuas), though it can occur in any breed and occasionally in cats. What Causes Tracheal Collapse? 1. Congenital (Genetic) Weakness Many affected dogs are born with weaker cartilage rings Genetic predisposition is strongly suspected 2. Degeneration Over Time Cartilage loses strength with age The dorsal membrane becomes lax and collapses inward 3. Contributing / Triggering Factors These do not cause the disease alone but worsen or trigger symptoms : Obesity → increases pressure on the airway Neck pressure (collars, pulling) Stress, excit...
