All dogs cough from time to time, but sometimes coughing  is a sign of a more serious health condition. Dogs make much sound when coughing, So it is only natural to take note when they are doing this.

Coughing is a reflex action that protects the respiratory system. When the body senses foreign material in the airway, it coughs to remove it so breathing can continue. Like humans, dogs cough to remove foreign objects, mucus, or debris from their airways so they can keep breathing well.

Dogs are social creatures. When they sniff each other, they share bacteria and viruses. Some of these can cause a dog to be sick. For example, a dog with a canine form of the flu might cough and sneeze then pass this disease on to another dog by physical contact or by leaving droplets of moisture from its nose on the ground. This virus is easily transfer from one pet to the other.

Allergens are substances in your dog’s environment that their immune system perceives as an invader. For example, if they are sensitive to dust or ingredients in their food, their immune system may react as if it were being attacked by a foreign virus or bacteria. This can lead to coughing, similar to what humans’ experience.

This condition is called congestive heart failure (CHF) and occurs when fluid builds up around your dog’s lungs. Certain dog breeds are more likely than others to develop this disease as they age. As a result, some dogs will cough as their disease progresses and fluid builds up around their lungs.
