Kennel cough

If you notice your  dog continuously dry coughing, has some nasal discharge and it is retching, this may point you to something. Kennel cough or also known as Infectious Canine Tracheobronchitis has these symptoms. It is named kennel cough because it is very contagious disease and spreads very fast in close quarters, like kennels, shelters or dog parks. Usually the ones that are most affected with this disease are dogs with lower immunity, like young puppies, pregnant dogs or dogs that suffer from respiratory diseases. In some cases, this disease can be mild and it can go away on its own, with the help of good nutrition and rest. In other cases, it can be more serious and require intake of antibiotics and anti-inflammatory medications. Depending on the severity of the disease and the treatment, you should consult your vet.

Chronic bronchitis

This disease manifests with inflammation of the bronchi and excessive mucus in the airways. Among humans this disease is mostly caused by smoking. In other words, if you smoke around your dog it can also be affected in the same way. Because the cough is productive it can become painful for your dog. Some other reasons for developing chronic bronchitis are dust and grains in the surrounding area, polluted air. If you are suspecting your dog has chronic bronchitis, take it to the vet and there you may get a prescription for corticosteroids for treating the symptoms.

Heart problems

One of the symptoms for heart problems is coughing. You should visit the vet if your dog is coughing in its sleep at night or even when it is just laying down. This can indicate congestive heart failure and heart enlargement. Congestive heart failure can cause fluid to build up in the lungs, which provokes cough for clearing up the fluid. Enlarged heart makes pressure on the lungs and the bronchi, and also provokes the dog to cough.

Fungal infections

Besides the fact that fungal infections are not common among dogs, they can be acquired from bird droppings, ponds or stagnant water. The fungal infections are followed with coughing, difficulty breathing and fever. If you notice these symptoms in your pet, you should most certainly take it to the vet for checkup. In case diagnosis of fungal infection is made, your dog may require antifungal medications for extended period.

Parasites

You must follow the prophylactic antiparasitic treatment, so your dog can avoid problems of this nature.
