Identifying the Secret Signs and Symptoms of Dog Heartworm

In the United States, one common canine disease is dog heartworm. Dog heartworm was first discovered in 1856. Heartworms in dogs are often found residing in the dog's heart and the major blood vessels.

The heartworms in dogs can seriously prevent a dog's heart from functioning properly. In worst cases, dog heartworms can cause blockage in the blood vessels. Dogs with heartworms tend to lose weight, have chronic coughing, be short of breath, develop chronic heart failure, have problems with their vision and eventually die.
