Causes of dog tracheal collapse

A study shows that canine tracheal collapse is due to the lack of chondroitin sulfate in the canine tracheal ring. Cushing's disease (hyperadrenalism) can cause the cartilage structure of the trachea to weaken. There is evidence that more than 50% of tracheal collapses are caused by the gradual weakening of tracheal cartilage and collapse of the trachea.
Some breeds of dogs are prone to tracheal collapse due to abnormal tracheal cartilage structure, and the tracheal lumen is relatively narrow. In addition, dogs that are obese or have chronic respiratory diseases are also prone to tracheal collapse. Tracheal collapse is more likely to occur in small dogs, such as Pomeranians, Chihuahuas, and Maltese.

What is canine tracheal collapse

The trachea can be divided into the cervical trachea and the trachea in the chest. The trachea in any part is caused by abnormal structure or compression by external factors, such as tumors. The phenomenon of tracheal stenosis is collectively called tracheal collapse.

Symptoms of tracheal collapse in dogs

1. Wild goose inhalation is a typical feature.
2. Coughing may become severe due to hot weather, excitement, or exercise.
3. Fainting may occur due to lack of oxygen.
4. Exercise intolerance.
According to the degree of tracheal collapse, it is divided into grade 1, grade 2, grade 3 and grade 4.
Grade 1: 25% of the trachea has collapsed.
Grade 2: 50% of the trachea has collapsed.
Grade 3: 75% of the trachea has collapsed.
Grade 4: 100% of the trachea has collapsed.
