Why is my pet coughing⁉️⁉️
Coughing is a common issue that leads many dogs to our clinic for evaluation. While it can be secondary to heart disease, it is actually more commonly associated with conditions outside of the heart. 🧐
-Tracheal cough: ➡️ Mainly small breed dogs and brachycephalic breeds can suffer from a collapsing trachea. The cartilage in the trachea can weaken with age and it can begin to fold in on itself. This stimulates the cough receptors within the windpipe leading to what is classically described as a 'goose-honking' sound. This cough often occurs after eating or drinking, when pulling on the leash or with excitement. 🍴
-Chronic respiratory diseases: ➡️ There are various respiratory diseases that can affect dogs. The most common is a condition called chronic lower airway disease or chronic bronchitis. This condition is irreversible, is often slowly progressive and is due to chronic inflammation within the lower airways. It usually manifests as a chronic intermittent cough that often waxes and wanes in its frequency and severity.
-Kennel cough: ➡️ Most dogs are vaccinated for Bordetella every year. Unvaccinated dogs can easily pick up kennel cough by direct contact with infected dogs. Playing with other unvaccinated dogs as well as sharing water bowls and toys are ways in which the condition can spread. Dog parks, doggie daycares and grooming facilities are also common areas where kennel cough can be spread in unvaccinated dogs. 🐶💉
-Allergies: ➡️ Just like humans, dogs can cough due to allergies. We can see allergic coughing due to environmental allergies like pollen, trees, grass. Dust, dust mites and mold are common indoor allergies. Water eyes, red skin, flaky skin, constant scratching are also common signs to see with allergies too. 👃
-Other Illnesses: ➡️ Some illnesses can cause coughing. For example: aspiration pneumonia, fungal infection, primary lung tumors, metastatic disease and heartworm infection. Other symptoms your animal can be experiencing is lethargy, fever, and anorexia. 🤒
Heart disease: ➡️️ Coughing in isolation (i.e. in the absence of other clinical signs) is actually less commonly associated with heart disease. A cough secondary to heart disease is usually new in onset and progressive over the course of days to a week. You will also often notice other clinical signs such as rapid or labored breathing, exercise intolerance, lethargy, and/or collapse. Typically, a heart murmur is noted on a physical exam and significant heart enlargement is detected on x-rays. 🩺
💕 Based on your pet's history and the results of a physical examination by your veterinarian, chest x-rays are often recommended as the initial diagnostic test to investigate for a cause of the coughing. Additional testing such as an echocardiogram, fluoroscopy, bronchoscopy, etc. may then be recommended for further evaluation. Coughing can be a frustrating and troublesome clinical sign in your pet, especially when it is impacting their daily routine and activities. However, please know that it is very common and there are various treatment options to help you, and your pet get some relief! 💕
