Dog bronchitis is the inflammation of the bronchial tubes. The general symptom is coughing. This may be a dry cough, a phlegm cough, or a mild, annoying cough such as humans often have during the resolution stage of Cory, or a cold. In some cases, the coughing may be so paroxysmal that it causes vomiting, and it is not unusual for a constant irritating cough to cause bleeding from the lining of the windpipe.
When inflammation is intense, shortness of breath is another symptom; the air spaces may become so constricted that the normal flow of air is retarded. Moreover, a considerable amount of mucus is discharged and this further interferes with normal breathing. Coughing is partly an attempt to rid the system of this phlegm.
The inflammation is symptomatic of the disease since bronchitis is seldom a disease entity in itself. Treatment of the cough in such cases usually involves the elimination of the underlying is-ease of which this inflammation is a part. Consequently, the first step must be an exact determination of the cause of the inflammation, as this will in turn determine the most effective treatment. Several viruses inflame these tissues; certain biologics may help combat bacteria that enter the tissue weakened by a virus infection.
If the inflammation is due to inhaling irritating smoke, gas, or dust, it may be advisable to prevent coughing to allow healing. Often there is the problem of deciding whether the cough produces irritation or vice versa. If the cough is productive, that is, if it raises phlegm, it would seem inadvisable to administer drugs that help stop the cough-in. But if a nagging cough merely irritates the membranes without serving a useful purpose, a drug like codeine may be used for relief. A dog’s coughing sometimes troubles the owner more than the dog, and in these cases stopping the cough is almost essential. A mixture of drugs, sold in every drugstore, is frequently prescribed by veterinarians. Some coughs are cured by the simple expedient of using sedatives to give the involved tissues as much rest as possible.
