A cough is a sudden, explosive exhalation of air that functions to clear material from the airways. Coughing is one way in which the lungs and airways are protected from inhaled particles. Coughing sometimes brings up sputum (also called phlegm), a mixture of mucus, debris, and cells expelled from the lungs. The cough reflex has both sensory (afferent) and motor (efferent) pathways. The internal laryngeal nerve carries the sensory information away from the area above the glottis in the trachea to the cough center located in the medulla oblongata via the vagus nerve. Stimulation of this area by dust or foreign particles produces a cough to remove the foreign material from the respiratory tract before it reaches the lungs. Mucus production in the bronchi is an airway defense mechanism, and it increases with inflammation and infection. In dogs and cats, coughing occurs because of a primary disease process, such as infection ("kennel cough") or chronic bronchitis in dogs, or feline asthma or heartworm-associated respiratory disease in cats. In most cases, addressing the primary disease will resolve the cough. Antitussive therapy is symptomatic and is primarily for the comfort of the animal and the owner. Most antitussive drugs are opiates or opioids that directly suppress the cough center in the medulla oblongata (see Table: ). The antitussive effect does not appear to be related to the binding of traditional opiate receptors (mu and kappa). For example, is an opioid derivative with good antitussive activity, but it does not have activity at opiate receptors and is not analgesic or addictive.

Preliminary results suggest that although maropitant may have antitussive properties leading to perceived clinical improvement, its failure to diminish airway inflammation makes it unsuitable for treatment of CCB. Future studies could evaluate maropitant as a cough suppressant for other respiratory disorders in dogs.

Most cases of tracheal collapse are treated with cough suppressants, bronchodilators, corticosteroids (to control inflammation), and/or . In obese patients, weight loss helps decrease respiratory effort. Although treatment is not curative, a study released in 1994 showed that 71 percent of dogs treated medically showed a good long-term response.
Ideally, give cough medicine just once in each 24 hour period.
