Can dogs eat onion or garlic?

No. Onion, garlic, leeks, chives, and shallots damage red blood cells in dogs and cats. All forms are toxic — raw, cooked, powdered, and in gravies. See our onion and garlic poisoning guide.

Are raw vegetables safe for dogs?

Many raw vegetables are fine — carrot and cucumber are popular. Cook hard vegetables like sweet potato for easier digestion. Avoid raw potato and green potato skins — they contain solanine.

How much vegetable can I give my dog?

Vegetables should be treats, not the main diet. A few small pieces alongside complete dog food is enough. Sudden large amounts of any vegetable cause gas and diarrhoea.
