🟡 Watch closely — call your vet, especially if it was a lot
Onions, garlic, chives and leeks (raw, cooked, or as powder in seasonings, soups and sauces) can damage dogs' red blood cells and cause anemia. Garlic is more potent than onion, and powders/concentrated forms are most dangerous. A tiny one-off taste is usually low risk, but a larger amount, repeated exposure, any powder/seasoning, or a small dog warrants a vet call. Signs can be delayed by several days.
