Heartworm Prevention in Dogs

What are the chances of a dog getting heartworms?

A potentially deadly disease for many species of animals, dogs are highly susceptible to heartworm infection.  Spread by infected mosquitoes, incidence rates are highest along the coasts and near major waterway, such as the Mississippi River. A recent study found that nearly half of all dogs not on a heartworm preventative in these areas came down with the disease.  With that said, heartworm disease has been reported in all 50 U.S. states.

What is heartworm disease in dogs?

Once bitten by an infected mosquito, the heartworm larvae will take about six or seven months to mature into adult heartworms inside your dog. They then begin to reproduce and congregate in the lungs, blood vessels, and the heart.  These adult worms can grow up to a foot in length and have a lifespan of five to seven years.  A dog can survive with as many as 250 worms in its system, although the disease will cause a whole host of serious health problems.

Because they are parasites, heartworms must feed of their hosts, specifically on the nutrients in their blood. When the worms grow into mature bloodsuckers and there are a large number of them, your furry friend will begin to experience symptoms of heartworm infestation.

The single most common sign your dog is suffering from heartworms is a precipitous decline in energy level.  Since the heartworms steal the nutrients your dog needs to stay active, your pouch may refuse to engage in activities once enjoyed, such as walking, playing fetch, or swimming. Your pet may seem lethargic or dazed, even during the day.

In extreme cases, your dog may lose a significant amount of weight, even if the diet remains unchanged.  A persistent, hacking cough is another unmistakable symptom of heartworm disease, since the worms also migrate to the lungs. Rapid breathing may ensue shortly thereafter.

Diagnosis of Heartworm Disease in Dogs

According to most veterinarians, your dog should be tested for heartworm disease at least once a year. If caught at an early stage, the immature worms are relatively easy to exterminate.  But once they have reached maturity, heartworms can cause serious health problems, even death. The diagnosis involves a simple blood test for antigens and is inexpensive and extremely accurate.

If your dog tests positive for the disease, treatment can take several months if the worms have reached adulthood, since they are more difficult to kill than immature worms.  It can also be quite painful and your furry friend will have to rest for several months following treatment to prevent dead worms from entering the lungs.
