Why is garlic more dangerous for dogs than for humans?

Dogs lack the specific enzyme needed to properly digest thiosulfate and N-propyl disulfide found in garlic. These compounds cause oxidative damage to a dog's red blood cells, forming clumps called Heinz bodies. This leads to hemolytic anemia, where the dog's body destroys its own red blood cells faster than it can replace them. While humans can process small amounts of garlic safely, even small doses can be life-threatening for dogs.

How much garlic is considered a toxic dose for a dog?

Scientific studies suggest that toxicity occurs when a dog consumes 15 to 30 grams of garlic per kilogram of body weight. For a medium-sized dog (around 25 lbs), ingesting approximately 10 cloves of garlic could lead to a medical emergency. However, smaller amounts given consistently over time can also cause cumulative damage to the blood. Powdered and dried garlic are even more potent and dangerous than fresh cloves.
