Coughing in dogs is not a disease, rather it is a symptom of some hidden illnesses such as Pyothorax, Kennel Cough, Canine Tuberculosis or other conditions such as congestive heart failure. A dog coughs or gags when food or foreign items get lodged in their throat. As a result of this coughing that foreign substance gets expelled. It also helps to prevent your dogs from more serious conditions such as pneumonia.
If your dog is coughing, dry, raspy or moist cough, it can signal different underlying ailments. A moist cough can indicate fluid in the bronchial cavities, and also can be the result of the presence of foreign material in their throat that may lead to severe inflammation, puss formation, edema, injury and even respiratory collapse.
