Summertime is upon us once more, that we know for sure, but do we remember what exactly Heartworm Disease is?  Well, let's break it down one last time to get a better grasp on what makes up the finer points of this intimidating disease.   

Heartworm, also called Dirofilaria immitis, can affect a wide variety of species, including dogs, cats, and ferrets. The mosquito is crucial in the development of the heartworms, and spread of the disease. Heartworm larvae enter an animal’s bloodstream after a bite from a carrier mosquito and grow into adult worms, which settle in the heart and large blood vessels.

Symptoms your pet may exhibit if heartworm positive are coughing, trouble breathing, and exercise intolerance, however some pets may show no signs. Since these symptoms can also indicate other illnesses you should see your veterinarian should your pet start exhibiting them.

Once your pet has been physically examined by a veterinarian, they will draw a small amount of blood from your pet to run a heartworm test.  Should your pet test positive for Heartworm disease the doctor will then discuss additional diagnostics with you.  Heartworm positive animals should have radiographs and bloodwork checked to evaluate severity of disease and any possible complications.

Heartworm positive dogs receive treatment in the form of an injection called melarsomine, which kills the adult worms. It is given in 2 doses over the course of 2 days. If microfilaria (baby worms) are present in the dog’s bloodstream then a medication called Ivermectin is given 1 month after initial treatment. It is very important to restrict your dog’s activity after being treated for heartworm, as serious and sometimes fatal complications can occur. Prevention is always easier than treating infection, so monthly preventatives and yearly blood tests are strongly recommended.
