Poor dog!

My name is Dawna & I am a foster home for over 40 animals. We are always getting dogs that are HW+. Over the past 7 years we have used Heartgaurd Plus Chewables once a month on our HW+ dogs. Lucky, HW count 5900, 3 yrs he is now negative & no arsenic treatment. Angel, HW count 2340, 9 months & she is now negative. Queenie, HW count 4600, 1 1/2 years heartworm negative. Being from Florida the mosquitos are very bad here but all our dogs that had heartworms are remaining negative as long as they get the Chewables every month. We also have learned that doing it this way does not damage the heart muscle like the arsenic treatment does. I hope this helps, it really does work & it is so much better on the dog.
