Third, a persistent cough can be caused by an underlying heart condition such as a heart-based tumor or a pulmonary edema
caused by heart failure. Heart conditions may cause coughing because
heart conditions can trigger fluid accumulation in the lungs. A cough
caused by a heart condition will typically be a wet-sounding cough and
will be accompanied by exercise intolerance.
Fourth, a cough can be a symptom that your dog has parasites. Two
of the most common parasites to cause coughing are roundworm and
heartworm. Roundworms usually make their home in your dog’s intestines.
Sometimes, however, the roundworms travel into your dog’s lungs. Once
in the lungs, the roundworms will migrate up the windpipe and be
coughed up. To learn more about roundworm prevention, signs and treatment click here.
Heartworm is a potentially fatal disease in which parasitic worms make
a home and grow in your dog’s heart. The cough associated with
heartworm often occurs when the disease has progressed unchecked for a
long enough time for the heartworm parasites to prevent the
transmission of oxygen-rich blood from between the lungs and the heart.
A dog who is coughing to due to heartworm will be very weak and even
walking or the slightest exercise will cause coughing. To learn more
