In very severe cases, the tongue and gums will appear blue as breathing becomes restricted. Activity is generally limited because the ability to breathe deeply when exercising is hindered. Left untreated, the restricted air flow can put undue stress on the heart and lungs as they try to compensate for the inability to breathe properly. Obese dogs are at greater risk than others. 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 leashes 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.
