Know Heartworm and how Heartworm Medicine can Help


                                                   Understanding Heartworm Disease

Heartworm disease in pets is a serious disease that is caused by a  microfilaria worm carried by mosquitoes.  When a carrier mosquito bites your pet, the worm will be passed into your dog's bloodstream. 

  • Affecting Your Pet’s Heart

When the microfiliaria worm is injected into your pet’s bloodstream, it is transported to your pet’s heart and goes through the blood vessels and to the pulmonary vessels of the lungs.  The worm is then actually protected by the pulmonary vessels and the heart which gives it the opportunity to grow up to several inches long.  Once the worm becomes an adult, it becomes capable of breeding with other heartworms and producing more microfilarias.  Mosquitoes pick up the new worms when they bite your pet and then carry the worms to other animals.

  • Risk Factors for Heartworm Disease

Dogs are more prone to developing heartworm disease.  While it is found in all 50 of the states within the United States, it is most concentrated in the eastern and southern United States.  It is also more common near the Midwestern river valleys and the areas along the Ohio and Mississippi Rivers.

Outdoor pets are also more likely to develop heartworm.  Indoor pets, however, can still develop the disease.  Even pets that never go outside have been known to get heartworms.  Therefore, all pets, whether indoor or outdoor should be protected from heartworms.

  • Effects of Heartworms

Heartworms cause damage to your pet’s blood cells and vessel walls.  The damage they cause results in scarring, clotting and narrowing of the blood vessels.  As a result, your pet’s blood pressure increases and causes the heart to pump harder.  Ultimately, the pet’s heart fails.  The more worms infesting the body, the faster this process takes place.  In addition, heartworms can live anywhere from three to five years while they destroy your pet’s heart.

  • Symptoms of Heartworms

Pets with heartworms will sometimes cough up the worms as they enter into their air passages.  This often looks as though  the pet is vomiting the worms.  In reality, these worms are coming from inside your pet’s lungs.  Pets with advanced heartworm disease will frequently cough,  tire easily, have a decreased  appetite, lose weight, abdominal swelling, experience fainting and have problems with their blood clotting.

  • Preventing Heartworms

A variety of heartworm medicines can be given to a pet in order to prevent heartworms from occurring.  These include Heartgard Plus (which is commonly mispelled as Heartguard Plus) and Proheart, which can be given monthly and Dimmitrol, which is given daily.  In order to provide your pet with the greatest protection, it should remain on heartworm medicine throughout its entire life.
