Garlic for Dogs: Why It’s Not Toxic and Actually Beneficial

For years, garlic has been labeled as toxic to dogs, often grouped with onions and other alliums. Many pet owners have been warned to keep garlic far away from their dogs' bowls. But is this really true? Or has misinformation led us to avoid something that can actually be beneficial?

The truth is, when fed in appropriate amounts, garlic is not only safe for dogs but offers a range of health benefits. In this blog, we'll break down the myths, the science, and how to safely incorporate garlic into your dog's diet.

Where Did the "Garlic Is Toxic" Myth Come From?

The fear around garlic toxicity stems primarily from studies that focused on onions and their impact on red blood cells. Onions contain thiosulfates, compounds that, in large amounts, can cause hemolytic anemia in dogs. Since garlic is also part of the allium family, it was assumed to have the same effects.

However, what these studies fail to highlight is that toxicity is dose-dependent—just like with many other foods, including salt and even water. The small amounts of garlic typically used in a dog's diet are nowhere near the levels required to cause harm.

The Science: What Research Says About Garlic for Dogs

Recent studies and holistic veterinarians have shown that garlic, when used correctly, has no toxic effects and provides multiple health benefits. Here’s what garlic does for dogs:

1. Boosts Immune Function

Garlic has powerful antimicrobial, antifungal, and antiviral properties. It helps strengthen the immune system, making dogs more resistant to infections, parasites, and even certain types of cancer.

2. Supports Cardiovascular Health

Garlic contains sulfur compounds that improve circulation, lower blood pressure, and reduce cholesterol levels. This can be particularly helpful for older dogs or breeds prone to heart disease.

3. Acts as a Natural Flea & Tick Repellent

Garlic alters the scent of a dog's skin and blood (in a way that humans and other pets can't detect), making them less appealing to fleas, ticks, and even mosquitoes. Many holistic pet owners use garlic as part of their natural parasite prevention plan.

4. Detoxifies the Liver

Garlic contains compounds that support liver function and help flush out toxins from the body. This makes it a great addition to diets focused on detoxification and overall wellness.

5. Has Anti-Cancer Properties

Garlic is rich in antioxidants and sulfur compounds that help fight oxidative stress, which is linked to cancer development. Some studies suggest that garlic can slow tumor growth and reduce the risk of certain cancers in dogs.

How to Safely Feed Garlic to Dogs

Like any powerful food, the key is moderation. The safe dosage of fresh, raw garlic for dogs is generally:

5-10lbs: 1/4 teaspoon 

10-15lbs: 1/2 teaspoon 

20-40lbs: 1 teaspoon 

45-70 lbs: 2 teaspoons

75+ lbs: 2 1/2 teaspoons

These amounts are the daily dose. Chop or crush the garlic and let it sit for 10-15 minutes before feeding, as this activates its beneficial compounds.


Precautions

Avoid garlic for dogs with anemia or those on blood-thinning medications.

Do not use powdered or processed garlic, as these may contain harmful additives.

Introduce it gradually and observe your dog’s response.



Final Thoughts

Garlic is not the dangerous toxin it's often made out to be. Instead, it's a powerful superfood that, when given in the right amounts, can provide a range of health benefits for dogs. The key is understanding proper dosage and feeding fresh, raw garlic rather than avoiding it out of fear.

So, next time someone tells you garlic is toxic for dogs, you’ll know the truth: it’s not about if they can have it, but how much they should have.
