Can dogs eat spinach?
The full picture
Spinach is a classic example of a 'healthy human food' that's a bit complicated for dogs. It's packed with vitamins A, B, C, K and iron — but it's also high in oxalic acid, which binds with calcium and can contribute to kidney damage over time. A small amount as an occasional treat is fine for healthy dogs. Dogs with existing kidney problems should avoid it entirely. Steamed or lightly cooked spinach is easier to digest than raw. Never add butter, salt, garlic, or onion (common pairings in cooked spinach recipes).
