Congenital cartilage abnormalities and a thin trachea predispose dogs to tracheal collapse. Toy dogs have more fragile tracheas than larger dogs and are therefore most prone to this condition. As the smallest breed overall, it is not surprising that Chihuahuas have the highest incidence of collapsing trachea Symptoms: The main symptom is a dry, honking cough which occurs when the dog tries to open its blocked airway. The cough can be aggravated by exercise, stress, pressure from a collar, and drinking or eating. Because coughing�and also barking�tend to irritate and further weaken the trachea, the condition progressively worsens. The result is increased coughing, gagging, shortness of breath when exercising, and sometime fainting. Severe cases are life threatening. (Note: If the dog becomes unable to breathe, briefly hold his mouth closed while blowing into his nostrils in an attempt to partially open the trachea. Of course, rush your pet to a vet.) Contributing Factors: Tracheal collapse is generally seen in older dogs but occasionally in young ones. Contributing factors are excessive weight, use of a collar with leash, respiratory infection, cigarette smoke and other air pollutants, and an enlarged heart. Treatment: Have a dog with symptoms examined by a vet for proper diagnosis and treatment. A collapsing trachea can generally be controlled through a weight-loss diet, the elimination of air pollutants, a low-stress routine, and moderate exercise. It is highly recommended that a proper harness (not the type with a strap across the throat) rather than a collar be used when walking the dog. Cough suppressants and mild sedatives can also be helpful. Surgery may be recommended in severe cases; it should only be performed by someone experienced in the procedure. Prevention: Take the following three simple steps to minimize the chances of your Chi developing a collapsing trachea: (1) use a proper harness instead of a collar when walking your dog, (2) control your dog's diet to ensure that he or she is not overweight, and (3) minimize your dog's exposure to cigarette smoke and other air pollutants. |
