Your dog makes all sorts of noises, and a lot of them probably sound like human coughs. In fact, a flu-afflicted person is often described as having a “barking” cough. But dogs can actually cough too, often sounding like you do when you’re congested and have a cold, or as though they are sneezing in reverse, since they may try to draw in a lot of air instead of forcing it out in a loud “Ah choo!” There are many possible causes for doggy coughing, according to Lynelle Johnson, DVM. She is an associate professor at the University of California at Davis, School of Veterinary Medicine. Here is her canine coughing compendium, which includes some of the primary causes for dog coughs, along with associated conditions.
- Kennel cough This illness often results from a combination of viral and bacterial intruders in canine airways. If your dog has a dry, hacking cough, sometimes accompanied by a white, foam-like saliva, it could have kennel cough. The most common airborne bacteria linked to kennel cough tend to spread in close quarters, such as dog kennels, boarding facilities, dog parks or other similar areas. This condition generally lasts one to two weeks and is treated with antibiotics and other prescription medications. Confine your dog until it’s recovered to avoid infecting other animals. And if you must go out during your dog’s recovery period, try using a harness instead of a collar and leash to discourage coughing reflexes.
- Chronic bronchitis This illness is characterized by excessive mucus in the airways that is triggered by inflammation. Smoking can cause canine bronchitis, so if you smoke, never do so near your dog. Pollution, dust and grains in the environment can also lead to inflammation. Ask your vet about corticosteroids to treat symptoms.
- Tracheal collapse This tends to occur in miniature and toy-size dogs that have a flat trachea, instead of a round or “C-shaped,” one. “When pressure changes within the airway during respiration, it collapses. Sometimes dogs can get infections or bronchitis in addition to airway collapse,” Dr. Johnson says. Treatment may include medication, surgery, or a combination of both.
- Heart disease Congestive heart failure can cause dogs to accumulate fluid in the lungs, which could lead to coughing, especially at night. Heart enlargement may also cause coughing. Dobermans, Boxers, Cocker Spaniels, and small dogs seem to be more vulnerable to heart disease and related coughing.
- Fungal infections Fungal infections can cause coughing, breathing difficulty, weight loss and fever. Your dog may require antifungul medications for extended periods, according to Dr. Johnson. Keep canines away from bird coops and droppings, as these can be fungal breeding grounds.
- Parasites Parasites, such as heartworm and roundworms, may also cause your dog to cough. These may be treated with dewormers, preventative pills and topical medications that your vet can provide.
- Foreign bodies Dogs can ingest a variety of substances and objects, like sticks or foxtails, which can lead to bouts of coughing. These plants may lodge in the gums or rear of your dog’s throat. If that happens, usually a vet’s help is needed to remove them.
- Lung cancer Coughing can be a symptom of this type of cancer, but it is rare in dogs. Nevertheless, it is good to have your veterinarian rule it out as a possibility. Canine lung cancer frequently will metastasize, or spread, from a tumor elsewhere in the body. If your vet suspects that your dog may have this disease, you could be referred to an oncologist, who can provide more specialized treatment.
- Pneumonia This serious illness is marked by “soft” coughing, heavy breathing and mucus. Pneumonia requires immediate attention, including antibiotics and fluids.
- Influenza A virus causes the flu, which is a relatively new disease in dogs. It is a very contagious respiratory infection that in its mild form includes coughing. In severe form, signs of pneumonia are present.
- Distemper Again, coughing may be a sign of this devastating, highly contagious viral disease that is transmitted from an infected dog’s respiratory secretions, urine or feces. It is easily prevented by vaccination.
Don’t rely on guesswork. If your dog’s bark sounds more cough than “ruff,” seek an expert’s opinion. Your vet can probably help to clear the cough so that soon both you and your dog may breathe a sigh of relief.
