Dog coughing causes

Kennel cough

Kennel cough is a highly contagious respiratory infection which causes dogs to have a persistent hacking cough. It usually isn’t serious and often clears up on its own within a few days. But it can become more severe in some cases, particularly for dogs that are very old, very young or have other health issues. Our in-depth advice article on kennel cough tells you everything you need to know.

Lung problems

Coughing could be a sign of an airway infection, bronchitis (inflammation of a dog’s airways) or pneumonia. In rare cases, it could be a sign of cancer. Your vet is best placed to make a diagnosis and discuss treatment with you depending on your dog’s individual circumstances.

Collapsing trachea (windpipe)

This is a fairly common condition in which the rings of cartilage which make up the windpipe begin to collapse, making it difficult for air to pass through from the nose and mouth to the lungs. An obvious symptom is a honking cough, often likened to a goose honking, among other symptoms. There is no single cause of tracheal collapse but factors may include a congenital defect and environmental factors. Small dogs are most susceptible to the condition.

Heartworm disease

Heartworms are not found in the UK but dogs can be at risk if they have travelled abroad. Heartworm disease is a potentially fatal condition which dogs can catch by being bitten by an infected mosquito. The parasitic worms can cause serious lung and heart problems.

Heart disease

When a dog’s heart muscle isn’t as strong as it should be, the additional pressure put on the lungs and airways can cause coughing. Fluid in the lungs caused by congestive heart failure can also can a dog to cough.
