When your dog is sick, it can be difficult to interpret the signs and figure out what he is trying to tell you. Coughing is very noticeable, and frequent coughing is definitely a sign that there is a problem.
Your veterinarian can help you determine what is causing your dog’s cough, and they can sometimes distinguish one kind of cough from another. High-pitched coughing and wheezing can indicate a narrowed airway, and coughing that occurs more frequently at night might suggest heart disease. For most coughing dogs or dogs with additional clinical signs like sneezing and fever, kennel cough might be the problem.
