As a devoted dog owner, it can be distressing to witness your furry companion coughing and gagging persistently. While occasional coughing might not be cause for concern, frequent or intense episodes could indicate an underlying health issue that requires attention.

As per Wag, although occasional coughing in dogs is typical, particularly if it results from eating or drinking hastily, excessive and unexplained coughing and hacking may indicate an underlying issue. Understanding the possible reasons behind your dog’s coughing and gagging can help you provide the necessary care and support.

Respiratory Infections

Respiratory infections, such as kennel cough or canine influenza, are common culprits of coughing and gagging in dogs. These infections are often accompanied by symptoms like sneezing, nasal discharge, and lethargy. If your dog has recently been in contact with other dogs, particularly in crowded or unclean environments, they may have contracted a respiratory infection.

Heart Disease:

Coughing, especially at night or after physical activity, can be a sign of heart disease in dogs. Conditions like congestive heart failure can lead to fluid buildup in the lungs, causing coughing and difficulty breathing. If your dog’s cough is accompanied by weakness, decreased appetite, or rapid breathing, it’s essential to seek veterinary care promptly.


Just like humans, dogs can suffer from allergies to environmental irritants such as pollen, dust, or mold. Allergic reactions can manifest as coughing, sneezing, itching, and skin irritation. Identifying and avoiding potential allergens, along with veterinary-recommended treatments like antihistamines or allergy shots, can help alleviate your dog’s symptoms.

Tracheal Issues:

Small dog breeds, such as Yorkshire Terriers and Chihuahuas, are prone to tracheal collapse, a condition where the cartilage rings supporting the trachea weaken over time. Coughing, especially when pulling on a leash or during excitement, is a common symptom of tracheal collapse. Providing your dog with a harness instead of a collar for walks and maintaining a healthy weight can help manage this condition.

Foreign Objects:

Dogs are curious creatures and may ingest objects that can become lodged in their throat or airway, leading to coughing and gagging. Common culprits include bones, toys, or small household items. If you suspect your dog has swallowed a foreign object, seek veterinary attention immediately, as it may require intervention to remove the obstruction safely.

Heartworm Disease:

Heartworm disease, transmitted through mosquito bites, can cause coughing, lethargy, and weight loss in dogs. Left untreated, it can lead to serious complications, including heart failure. Yearly heartworm testing and preventive medications prescribed by your veterinarian are crucial for protecting your dog against this potentially life-threatening disease.

In conclusion, persistent coughing and gagging in dogs should never be ignored. While some causes may be relatively benign, others can indicate serious health problems requiring prompt veterinary care. By staying vigilant and seeking timely medical attention when needed, you can ensure your canine companion stays happy, healthy, and free from discomfort.
