Q: Once my dog has heartworms, what’s the treatment? How much will it cost?
A: The drug that you treat with is called Immiticide. It’s an injectable, arsenic-based product. The dog is given two or three injections that will kill the adult heartworms in the blood vessels of the heart.
The safest way to treat heartworms includes an extensive pre-treatment workup, including X-rays, blood work, and all the tests needed to establish how serious the infection is. Then the dog is given the injections. With all the prep work, it can run up to $1,000. But just the treatment can be done for about $300 in some areas.
