If your dog suddenly starts to make gagging noises or cough, it can be alarming. Sometimes, it's just a single cough or gag, while other times it is chronic problem. If the symptoms are ignored and there is an underlying disease causing them, things can progress to a potentially life-threatening situation. Find out what causes a dog to cough or gag and what you can do to help prevent unnecessary issues from developing.
Is It a Cough or a Gag?
A cough and a gag are similar but not the same. A cough is a hacking noise that occurs when your dog is forcing air out of its throat and mouth. A gag is a retch that is similar to vomiting but nothing comes up and out, except maybe a little phlegm or mucous. Sometimes a dog will both cough and then gag at the end of the cough but either can happen on its own, too.
Causes of Coughing or Gagging in Dogs
Airborne debris, food, diseases, and more can result in your dog to develop a cough or to gag. Knowing what the cause of your dog's symptoms are may help you determine whether or not they are serious.
Sometimes a dog will eat so quickly that its food will go down its trachea instead of its esophagus. This can cause a dog to cough or gag in an attempt to get the food out of the wrong tube. In this case, you could encourage your dog to eat more slowly and place food in a bowl that is at an appropriate height for the size of your dog.
If a dog has a disease that affects its respiratory tract, coughing and/or gagging may occur. Inflammation and irritation of the trachea or lungs are the causes of these symptoms and until it is treated, the coughing and gagging will continue. Pneumonia, kennel cough, influenza, tracheitis, lungworm infestations, fungal infections, distemper and other diseases that cause respiratory tract issues will require veterinary attention.
Certain types of heart disease can cause a dog to cough. Fluid accumulation in the lungs can lead to coughing and difficulty breathing. Heartworm disease can interfere with heart function and cause inflammation within the lungs. With these conditions, a dog is likely to cough and gag in an attempt to clear its airway, but that won't help. Only veterinary attention can get your dog some relief.
If a dog is nauseated or experiencing gastrointestinal reflux, gagging may occur. Dogs with chronic reflux can develop a chronic cough.
Some dogs, especially small breeds, are prone to tracheal collapse. This occurs when the cartilage holding the trachea open weakens. Coughing may result due to decrease in the opening of the airway.
Diagnosing the Cause of the Cough or Gag
Your veterinarian will perform a full physical examination and obtain a patient history to see what may be causing your dog to cough or gag. X-rays, bloodwork, echocardiograms, and other tests may be needed to make a diagnosis depending on what your vet suspects the problem is.
Treatment for Coughing or Gagging
Depending on the reason for your dog's coughing or gagging, the treatment plan will vary. If your dog is diagnosed with a disease or illness that requires short-term treatment, medications including antibiotics, steroids, and cough suppressants are likely to be prescribed. Dogs diagnosed with heart disease may be prescribed life-long medications to manage the disease and symptoms. If the problem is so severe that your dog is not well oxygenated, oxygen therapy may be needed, too.
How to Prevent Coughing or Gagging in Your Dog
While you can't prevent all things that can cause your dog to cough or gag, there are still several things you can do. Keep your dog current on its vaccinations, on heartworm prevention, and away from dogs that are not fully vaccinated or sick. Additionally, regular check-ups with your veterinarian can help with prevention and early diagnosis so your vet can start treatment as soon as possible.
