Coughing in dogs is completely normal if it’s just the odd cough here and there. It’s a simple way for your pet to get rid of dust, germs and other things they’ve breathed in from their environment. However, if they seem to be coughing a lot, it could be a sign of something more serious.
Why is my dog coughing?
As a dog owner, you know that your four-legged friend spends the vast majority of their life sniffing. Unfortunately, this behaviour also makes them more prone to picking things up like bacteria, parasites or viruses which could lead to diseases or illnesses where coughing is a symptom. Below we discuss the most common diseases and illnesses that can result in coughing in dogs.
With this disease the coughing will sound soft and continuous and it will likely worsen at night or when your pet is lying on their side. Apart from coughing, your dog may also show decreased energy or stamina. Common treatments for heart disease in dogs involve medication and a change in diet.
2. Kennel cough
Kennel cough is a highly contagious illness that causes inflammation and infection of the windpipe and main lower airways. Dogs that spend time in groups such as at day-care, training classes or that tend to walk in areas with high population of dogs are more at risk of catching this disease. However, many dog carers now require canines to be vaccinated against kennel cough before entering their care.
If your dog has kennel cough, it sounds like a hacking, dry and raspy cough which will usually go away on its own within a week or two. However, it’s still a good idea to take your dog to the vet as your pet may need antibiotics or cough suppressants.
One of the reasons why your dog keeps coughing may be pneumonia. This is an infection that results in inflammation of the lungs which can be caused by bacteria, viral infection, regurgitation, metabolic disorders or swallowing difficulties. Coughing in dogs caused by pneumonia will sound wet and soft and there may be other symptoms present such as high fever, lack of appetite and lethargy. If you suspect your dog has pneumonia, get them to the vet as soon as possible for treatment.
4. Collapsing trachea
This condition is most common in smaller or obese dogs and results from collapse of the rings of cartilage that make up the windpipe. This makes it very difficult for air to pass through the nose and into the animal’s lungs. If your dog keeps coughing, it sounds similar to a goose-like honking, and it gets worse if your dog pulls on the leash, the coughing may be caused by a collapsing trachea. If the trachea has completely collapsed, your dog may sound almost asthmatic. Treatment for this condition can include weight loss, cough suppressants, steroids, bronchodilators and antibiotics.
Heartworm is spread by mosquito bites. This disease may be a concern if you’re planning on going on holiday with your pet. If you’ve been abroad with your pet and they now have a mild and persistent cough paired with lethargy, weight loss and a lack of appetite, the problem could be heartworm. If you’re going away with your dog to a country where heartworm may be a problem, it may be possible to get an injection or medication to prevent this, so speak to your vet for more information.
6. Canine influenza
Canine influenza is the equivalent of the flu in humans and is a very common cause of coughing in dogs. This respiratory infection will typically last between two weeks and a month and it’s likely your vet will give your dog medicine and recommend quarantining your pet from other dogs as the disease is very contagious. Fortunately, you can avoid most forms of canine influenza by keeping your dog’s vaccinations up to date.
7. Foreign bodies
It’s no secret that dogs are curious, but sometimes this trait can land them in a spot of trouble, particularly if they try to eat something that they shouldn’t. If your dog chomps something like a small toy or bone, it may get stuck in their throat and cause them to choke, causing a cough-like sound. If you think your dog has swallowed or eaten something they shouldn’t have, contact your emergency vet as soon as you can.
