给你一个预算。 从Pets.webmd.com 来的。

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.

另外不知你领养的地方有没有医生。 一个朋友领养了一个狗狗，有心脏病。那地方有医生，只要她带狗狗去领养的地方看医生就很便宜。因为领养的地方不是为挣钱的。

祝好！
