Heartworm Disease: How To
Protect Your Pet
Heartworm
Disease Facts
Every year thousands of dogs contract Heartworm disease.  This often fatal
disease, which is spread by mosquitoes, can be prevented.  Because of the
mosquito population in this state (some even refer to it as the state bird!) we
must all be diligent in testing for and providing prevention medication to
ensure our companions life is as long and full as possible.
Testing for this disease is easily done at your pets annual exam.  A technician
will draw a blood sample from your pet and perform a Heartworm  "snap" test.  
This test will detect the antigen in the blood which signals a Heartworm
infection.  

Our Heartworm test also tests for other diseases common to this area due to
our tick population.   Lyme disease, Ehrlicia , and Anaplasmosis are all
covered with one test.  These three diseases are all tick born diseases.  
Catching these diseases early will give your pet a better chance of a full
recovery.

  • Have your pet examined annually by a
    veterinarian
  • Have your pet tested once a year for
    Heartworm disease
  • Provide your pet with Heartgard Plus
    Chewable Tablets once a month year

A mosquito must ingest the microfilaria before they can become infectious. The mosquito must then inject
the Heartworm larvae into the susceptible pet. It takes 3 to 6 months for adult   Heartworms to develop in a
dog after an infected mosquito bites it.

Heartworms occur in all breeds of   dogs:  large and small, short haired and long haired, inside-dogs and
outside-dogs.  Heartworms also are now known to infect cats.

Treatment is very SUCCESSFUL when the disease is detected early. The adult worms are killed with an
injectable drug given in a series of 2 - 3 injections. A few days later, the worms begin to die, and are carried
by way of the bloodstream to the lungs where they lodge in small blood vessels. They slowly decompose
and are absorbed by the body over a period of several months.   

Once you have treated a Heartworm infection, you should give your pet Heartgard Plus every month in
order to be certain none of the Microfilaria left from the adult Heartworms have a chance to reinfect your
pet.

If a dog is infected with heartworm disease they can be treated.  This is done with a series of injections.  
Before the injections can be given however, the dog must undergo x-rays and blood work to determine the
severity of the disease.

Once the severity of the heartworm disease is determined, the dog will undergo a series of injections in the
muscle along the spine.  The number of injections will depend on the severity of the disease.  

The worms will then break up and enter the bloodstream to the lungs where they lodge in small blood
vessels. They slowly decompose and are absorbed by the body over a period of several slowly

During the period of time in which the Heartworms are decomposing it is very important to keep the
infected dog very quite.  Owners are instructed to take the dog out for "bathroom breaks" only on a leash,
and to never let the dog run, jump around or become excited.  Doing so may allow large pieces of the adult
Heartworm to cause a sort of clot in the veins of the blood vessels of the lungs, causing the dog to die.

Once you have treated a Heartworm infection,  Heartgard Plus must be given every month in order to be
certain none of the Microfilaria left from the adult Heartworms have a chance to reinfect the dog.

Heartworm Disease
BENEFITS OF YEAR-ROUND PREVENTION:

  • Mosquitoes can survive the winter inside your home. A mosquito which is
    carrying Heartworm disease is as much of a threat to your dog in the
    winter as in the summer. Only one bite can infect your pet.

  • Convenience. It will be more convenient to “stay on schedule” to remind
    you to give the Heartworm prevention.

  • Provides protection for dogs that travel to warmer climates during the
    winter.

**HEARTWORM CHECKS ARE STILL RECOMMENDED EVERY OTHER YEAR
EVEN WITH YEAR-ROUND HEARTWORM PREVENTION, AND AN ANNUAL
WELLNESS EXAM IS REQUIRED TO PURCHASE PREVENTATIVES!!!

Reasons for this include:

  • The Heartworm preventive medication may be vomited or spit out by your
    dog without your knowledge, thereby, exposing your pet to Heartworm
    disease.

  • Either by accident or oversight, you may forget to give the monthly
    preventive.

  • None of the routine Heartworm tests are able to detect immature or early
    Heartworm  infestation.  Your dog may have had an undetectable infection
    at the time of his/her last Heartworm test, and therefore, could have a
    dangerous infection. Heartworm preventives WILL prevent new infections
    of Heartworms, BUT it CANNOT prevent the progress of pre existing
    Heartworm infection.
