Some dog owners swear by mixing a little garlic into their pup’s dinner, usually as a natural way to ward off fleas and parasites. But here’s the thing: just because garlic is a heart-healthy superfood for us humans doesn’t mean it’s a treat for our furry friends. In fact, it can be quite the opposite. Let’s dive into why garlic can actually be dangerous for dogs.
Why Garlic Can Be Harmful
The “secret ingredient” in garlic is a compound called allicin, which is what gives it that signature pungent smell. While allicin is famous for its antibacterial properties in humans, dogs lack the specific enzymes needed to break it down. If they ingest it, it can lead to serious issues like toxicosis and life-threatening anemia (a drop in red blood cells).
Is It All About the Dosage?
To give you an idea of the risk, a whole bulb of fresh garlic could be acutely life-threatening for a 20-pound dog. And if you’re looking at garlic supplements or capsules, the concentration is usually much higher. You might be thinking, “I’d never give my dog that much!” but keep in mind that the effects can be cumulative. Even small amounts—like a single clove a few times a week—can build up over time and become dangerous. Plus, every dog is different; some breeds are much more sensitive to garlic than others.
