Learn how much garlic is safe for dogs! This guide explains the correct dosage based on weight, its health benefits, and why garlic can be a natural flea repellent.
Is Garlic Really Toxic to Dogs? Here’s What Science Says
For decades, garlic has been grouped with onions as toxic to dogs, primarily due to their shared classification in the Allium plant family. But is garlic actually harmful? Or has it been unfairly linked to its “kissing cousin,” the onion?
Scientific research shows a clear distinction between garlic and onions regarding their effect on a dog’s red blood cells.
💡 According to Dr. Dave Summers on IVC Journal:
➡ Onions have 15 times the ability of garlic to cause oxidative damage to red blood cells.
➡ Garlic’s thiosulfate content (the compound linked to Heinz body anemia) is barely traceable and readily excreted by dogs.
If garlic were as dangerous as onions, my own dogs—who’ve been on natural brewers yeast and garlic flea & tick prevention for years—would have suffered health issues. Instead, they’ve outlived breed expectations! Our last dog lived to age 17—a testament to the benefits of holistic nutrition.
