A cough in dogs can range from a minor annoyance to a sign of a serious health issue. Understanding the different types of coughs, their potential causes, and accompanying symptoms is crucial for ensuring your canine companion receives the best possible care. This guide will help you decipher your dog’s cough and know when it’s time to consult a veterinarian.
Recognizing Different Dog Cough Sounds
The sound of your dog’s cough can provide valuable clues about its origin. Paying close attention and even recording the sounds can be helpful when discussing symptoms with your vet. Common cough sounds include:
- Hacking cough: This sounds like your dog is attempting to clear something from their throat.
- Honking cough: Similar to the sound a goose makes, this can indicate issues with the trachea or larynx.
- Wet cough: A moist, phlegmy cough, sometimes accompanied by gurgling sounds, may suggest fluid in the lungs.
- Gagging, then coughing: This sequence can indicate a problem with swallowing or the esophagus.
Coughing vs. Gagging in Dogs
It’s important to differentiate between coughing and gagging. A cough is an involuntary reflex to expel irritants like dust, mucus, or foreign objects from the lungs and airways. Gagging, on the other hand, is a reflex often associated with swallowing difficulties, blockages in the esophagus, or regurgitation. Gagging typically involves an open mouth with the tongue thrust forward and may be more noticeable when the dog is eating or drinking. The order in which your dog coughs and gags can be a key piece of information for a veterinarian.
Common Causes of Coughing in Dogs
Several factors can contribute to a dog’s cough:
Kennel Cough
Also known as infectious tracheobronchitis, kennel cough is a highly contagious respiratory illness often contracted in places where dogs congregate, such as boarding facilities or doggy daycare. It typically presents as a dry, honking cough that can persist for days or weeks. While usually not serious in healthy adult dogs, it can lead to pneumonia in very young or old dogs if it progresses to the lungs.
Laryngeal Paralysis
Certain large breeds, including Labrador Retrievers, Golden Retrievers, Weimaraners, Bernese Mountain Dogs, and Great Danes, are predisposed to laryngeal paralysis, usually affecting dogs over five years old. This condition impairs the larynx’s ability to close properly during eating, drinking, and swallowing, allowing food debris or water to enter the airway, triggering a cough. Management may include elevating food and water bowls and avoiding neck-related restraints. Avoiding strenuous activity during hot weather is also advisable.
Tracheal Collapse
Small breed dogs can develop weakened tracheal rings as they age, leading to tracheal collapse. This often results in a honking cough, especially when the dog becomes excited or active, and typically subsides when they calm down. While not usually life-threatening, medications can sometimes help, and managing excitement levels is key to reducing occurrences.
Pulmonary Issues
A wet cough, often described as slurpy or gurgling, can indicate lower airway or pulmonary problems, potentially signaling pneumonia. This type of cough, accompanied by labored breathing, is considered the most serious among the common cough types.
Other Potential Causes
Parasites like heartworm and roundworms can also cause coughing. Though rare, canine influenza (a viral infection) has been responsible for localized outbreaks. Chronic bronchitis and heart disease can also manifest as coughing, particularly during exercise.
Assessing the Seriousness of Your Dog’s Cough
An occasional cough is not automatically a cause for alarm, especially if your dog quickly returns to normal, energetic behavior. Sometimes, a dog simply needs to clear an irritant from its airways. However, persistent or severe coughing warrants closer observation and potential veterinary intervention.
Observing Your Dog’s Cough and Other Symptoms
As a dog parent, it’s vital to observe your dog’s coughing patterns and any accompanying symptoms. Consider the following:
- Timing: Does the cough occur more frequently at specific times, such as at night when lying down?
- Environmental Irritants: Are there potential irritants in your dog’s environment, like strong perfumes, air fresheners, pollen, or cold air near an open window?
- Accompanying Symptoms: Is the cough associated with lethargy, loss of appetite, difficulty breathing, sneezing with colored mucus, red eyes, or fever? These can indicate a more serious respiratory infection or other medical condition requiring veterinary attention.
What Your Dog is Coughing Up
The nature of what your dog coughs up can also provide important diagnostic clues:
- Coughing up Blood: This is a serious sign and requires immediate veterinary attention. It could indicate internal injury, heartworm disease, pneumonia, or in severe cases, cancer.
- Yellow, Green, or Brown Mucus: This suggests a possible respiratory infection, and a veterinary appointment is recommended for diagnosis and treatment.
- Clear Liquid, Mucus, or White Foam: Generally, these indicate less severe irritation from environmental factors like smoke, pollen, or household chemicals. Clear mucus is less likely to be associated with an infection. Mucus plays a vital role in trapping and expelling irritants.
If your dog is coughing, identifying the underlying cause is essential for effective treatment. For immediate veterinary consultation, especially outside of regular office hours, consider using a telemedicine service like Airvet.
