Heartworm treatment deals with the prevention and treatment of heartworm diseases. The overall veterinary treatment market has been growing in the past few years, due to the increasing awareness towards veterinary healthcare. Heartworm disease is a severe, fatal disease, which is generally found in pets. Heartworm disease is usually caused by foot-long worms present in the lungs, heart, and associated blood vessels of affected pets. Heartworm disease causes severe heart failure, lung disease, and damage to other organs in the body. Heartworm disease affects pets like cats, dogs, and ferrets. In addition, these worms also live in other mammal species such as coyotes, wolves, sea lions, foxes, and others. Species like coyotes and foxes live in proximity to many urban areas, thus, they are considered as important carriers of the heartworm disease. Dogs are considered to be a natural host for heartworms. It has also been found that, heartworm disease in cats is very different from heartworm disease in dogs. Cats are a typical host for heartworms. The symptoms of heartworm disease include a mild persistent cough, fatigue after moderate activity, reluctance to exercise, weight loss, and decreased appetite. Heartworms are spread through the bites of mosquitos that carry the infective heartworm larvae. The larvae continue to mature in the dog's heart and lungs. Dogs are usually treated with three injections, namely: melarsomine, doxycycline, and prednisone. The melarsomine injection kills the adult heartworms and reduces the chances of unwanted side effects. Moreover, a severe case of heartworm disease requires a surgery to remove the worms from the heart and vessels within the lungs.
