Heartworm Disease:  Removal of Microfilariae

         --------------------------------------------

                      General Information



Now that your pet has been treated for adult heartworms, the

immature worms (microfilariae) must be removed from the blood to

prevent your pet from serving as a source of infection for other

dogs.



Microfilariae are eliminated with medication.  After the

treatment period, a blood sample will be checked.  If

microfilariae are still present, treatment is repeated until the

blood is free of microfilariae.



After the doctor is certain that all microfilariae have been

eliminated, a program of preventive medication is instituted so

your dog does not become reinfected.



                 Important Points in Treatment



1.  Give all medication as directed.  Call the doctor if you

    cannot give the medication.



2.  Special instructions:





       Notify the Doctor if Any of the Following Occur:



    * Your pet refuses to eat or seems depressed.



    * Your pet vomits the medication or food.



    * There is a change in your pet's general health.
