Prevent Heartworm Naturally

Where To Start?

Almost every day, I get asked the question of whether you can use something to treat and prevent heartworm naturally in pets.

Ivermectin is a common medication known to be used to kill many different types of parasites. It’s most currently used in monthly heartworm prevention. It has also been used to treat ear mites as well as hair mites, which can cause mange. It is used to treat some internal parasites as well but is not used predominantly for this. According to the Pet Health Network, “certain dogs are genetically hypersensitive to the medication. In these dogs, Ivermectin can pass directly to the brain and be toxic or even lethal. Sensitivity to the drug can also be seen in dogs or puppies that have overdosed on a similar medication in the past.”

Hearworm Lifecycle

Genetic sensitivity to Ivermectin can be seen in several breeds, but is more commonly seen in the following breeds:

  • Collie
  • Old English Sheepdog
  • Shetland Sheepdog (Sheltie)
  • Australian Shepherd
  • German Shepherd
  • Longhaired Whippet
  • Silken Windhound
  • Border Collie
  • Dogs of mixed breeds that include herding breeds

“This genetic sensitivity is due to a mutation in what is called the MDR1 gene. This mutant gene may make the dog more sensitive to several other medications as well. Not all individual dogs in the breeds listed above carry the mutant gene. The only way to know if an individual dog has the mutant MDR1 gene is through testing. To do the test, cells are scraped from the inside of the dog’s cheek and sent to a laboratory for genetic testing. Talk to your veterinarian if you are interested in having your dog tested.” (Pet Health Network)


If your dog has Ivermectin toxicity, you may see any of the following symptoms:

  • Lethargy
  • Depression
  • Drooling
  • Vomiting
  • Dilated pupils
  • Loss of appetite
  • Disorientation
  • Tremors/Seizures
  • Blindness
  • Trouble standing
  • Slow heartbeat
  • Difficulty breathing
  • Coma
  • Seizures

Ivermectin toxicity can’t be reversed, unfortunately. If the drug was given within the past 4 – 6 hours, you or your veterinarian can induce vomiting and provide your dog activated charcoal to help minimize the amount of Ivermectin that is absorbed.

Additionally, your veterinarian may perform the following tests:

  • Chemistry tests to evaluate kidney, liver, and pancreatic function, as well as sugar levels
  • A complete blood count to rule out blood-related conditions
  • Electrolyte tests to ensure your dog isn’t dehydrated or suffering from an electrolyte imbalance

So, how can I prevent heartworm naturally? 

As of late, many new all-natural, effective, alternative medications have come to the market that has shown to be very powerful at preventing and treating heartworm. One such product is called HWF (Formerly Heartworm-Free)

The ingredients included are:

-Organic Hawthorne Berries:  These amazing berries support the circulatory system, strengthen the heart, tone the heart, feed the adrenals, cleanse arteries, and has been known to assist in balancing blood pressure.

-Organic Garlic- Repels mosquitoes that might be carrying heartworms with them. Its pungent taste and smell are guaranteed to ward off those flying insects. So, in essence, garlic may be able to help you prevent heartworms but not get rid of them. Garlic also has a catch: it is poisonous to heartworms.

-Organic Sheep Sorrel- Contains inulin, amino acids, sulfur, zinc, potassium, and phosphorus, vitamin A, C, calcium, magnesium, manganese, selenium, germanium, and B-complex vitamins. These all help detoxify the body, support the immune system, and have been known to improve circulation.

-Organic Citrus- Citrus has been known to support heart functions, and a healthier heart promotes proper pH balance, helping the body neutralize mild cases of acidity in the blood.

Keep in mind that mosquitos are the major carrier or heartworm, so if you want to prevent heartworm naturally, you must do whatever you can to repel these pests with a product like our All-Natural Flea & Tick Bundle!
