Can dogs eat kale?

Caution — small amounts only

Kale is nutritious but high in oxalates and isothiocyanates that can cause kidney and GI issues in dogs. Small amounts occasionally are fine.

The full picture

Kale is another superfood that's more complicated than it seems for dogs. It contains calcium oxalate (kidney/bladder stone risk over time) and isothiocyanates (GI irritation). Some dogs also struggle with the fibrous texture. A small amount of plain cooked kale as an occasional treat is unlikely to cause problems in a healthy dog, but regular feeding isn't recommended. Dogs with kidney or bladder stone history should skip it entirely. Never fry kale in oil or serve with garlic or onion.
