  As a small breed, and an older dog, I worry that Chico may be showing signs of collapsing trachea, heart or pulmonary problems. I recommend getting him seen by your vet to try and get to the bottom of his coughing.
  
  A little more about collapsing trachea. The trachea is supported by tough rings made of cartilage. Occasionally, the trachea will lose its rigidity and collapse while the dog is breathing. For unknown reasons, the cartilage rings weaken and the trachea no longer has proper support. It happens most often as a result of excitement or exercise.
  
  The symptoms depend on the severity of the deterioration. Usually, the dog will have difficulty breathing, especially during exercise. The deeper the pet tries to inhale, the more the trachea collapses, further restricting air flow (similar to sucking on a straw too hard). The pet appears to tire easily as it becomes short of breath. Dogs with a collapsing trachea will generally cough as if trying to clear the airways, and occasionally this cough will sound like a goose honk. In very severe cases, the tongue and gums will appear blue as breathing becomes restricted.
  
  Examination with the fingers and radiographs (x-rays) will generally confirm the diagnosis. Depending upon the severity of the condition, medications will help. Veterinarians usually prescribe drugs to help dilate the airways. The coughing is controlled by cough suppressants such as Torbutrol. If the pet is obese, we suggest a stricter diet. Finally, activity should be restricted and not encouraged. Dogs with collapsing tracheas should wear harnesses instead of collars in order to take any pressure off of the trachea. With the help of medication and modification of lifestyle, the collapsing trachea can be controlled but seldom cured. In severe cases, surgery to help open the airways may be beneficial, but most cases are managed medically not surgically.
