What Causes Older Dogs to Cough?

Kennel cough: This is a respiratory infection that is common in dogs of all ages, but it is more severe in older dogs. Kennel cough is caused by a variety of bacteria and viruses, and it is spread through contact with other infected dogs. Symptoms of kennel cough include coughing, sneezing, and a runny nose.

Heart disease: Heart disease is a common cause of coughing in older dogs. When the heart is not able to pump blood effectively, fluid can build up in the lungs and cause coughing. Symptoms of heart disease in dogs include coughing, difficulty breathing, exercise intolerance, and weight loss.

Cancer: Cancer is another possible cause of coughing in older dogs. Some types of cancer, such as lung cancer and lymphoma, can cause coughing. Symptoms of cancer in dogs can vary depending on the type of cancer.

Other causes: Other possible causes of coughing in older dogs include:

* Allergies: Allergies can cause coughing, sneezing, and itchy eyes.

* Asthma: Asthma is a respiratory condition that causes inflammation and narrowing of the airways. Symptoms of asthma in dogs include coughing, wheezing, and difficulty breathing.

* Foreign objects: Foreign objects, such as grass blades or pieces of food, can get lodged in the throat or lungs and cause coughing.

* Collapsing trachea: Collapsing trachea is a condition in which the trachea, or windpipe, collapses. This can cause coughing, wheezing, and difficulty breathing.
