Are there any holistic or over-the-counter dog heartworm preventatives?

I cannot say for sure if there are. I'm sure that there are, but I don't know what they are, and I definitely don't recommend them.

No, there's really nothing that I know of that can prevent heartworm that is not a prescription FDA-regulated product. So I wouldn't recommend anything like that.

At this point, no. There is not anything effective for treating heartworm disease. And so the simple answer to that is no, there's not.

No, there are none that we would recommend. In dogs with heartworms and baby worms circulating in their blood, some of these heartworm preventatives are not appropriate in that situation, as dogs can have an allergic reaction if they have baby worms circulating in the blood with certain products. We avoid those products in the initial treatment of a positive dog because of that.

Absolutely not. There are some online claims that there can be preventatives or treatments. There's even a Guinness remedy out there, but those are absolutely not effective.

No, there are no holistic or over-the-counter heartworm preventatives that are considered safe or effective.

Unfortunately, no FDA-regulated holistic or over-the-counter heartworm preventatives exist. Some products may claim to prevent heartworm disease, but they're not effective, and your pet will likely still contract heartworm disease.

Not that we recommend.
