How to Prevent Heartworm


This is the second post in a two-part series. This post focuses on how to prevent heart worm. Read the first post to learn the misconceptions about heart worm and understand what heart worm really is.

The American Heart worm Society (AHS) recommends year-round chemical preventives for every dog over the age of eight weeks; however, research shows the AHS is backed by eight pharmaceutical companies and has a vested interest in promoting and selling heart worm drugs, despite the drugs' harmful side effects. If conventional medicines aren't safe, how can we protect our pets while preventing heart worm?

How to Prevent Heart worm 

Conventional medicine recommends preventing heart worm by feeding your pet once-a-month tablets. However, evidence is beginning to show that these pharmaceutical drugs aren't necessarily safe for your pet.

Ivermectin, the active ingredient in some heart worm tablets, can cause liver problems, vomiting, diarrhea, depression, seizures, paralysis, auto-immune diseases, pneumonia, aggression, and sudden death, among other side effects. Collies, Australian shepherds, she lties, border collies, and old English sheepdogs are particularly susceptible to the toxicity of ivermectin.

Herbs, such as neem bark powder, are another way to help prevent heart worm. Because herbs also promote overall wellness, including digestive health and balance, clean blood, and a strong immune system, they can make pets less susceptible to heart worm—preventing your furry friends from getting infected in the first place!

Because heart worm is carried by mosquitoes, we can also protect our pets by preventing mosquito bites. Clear any standing water (mosquitoes breed in standing water) near your pet's play areas and use a flea, tick & mosquito repellent to keep mosquitoes away from your pet.
