Can Dogs Eat Cooked Cabbage? Yes — cooked cabbage is fine in moderation

Q: Can dogs eat cooked cabbage?

Yes. Plain cooked cabbage is safe for dogs in moderation and is actually easier to digest than raw cabbage. Avoid any cabbage cooked with butter, salt, onion, or garlic.

The full picture

Cooked cabbage is one of the better cooked vegetables to share with a dog. Cooking breaks down the tough cell walls, making it more digestible, and softens the goitrogenic compounds that can interfere with thyroid function in raw cabbage when eaten in large amounts.

The golden rule: plain. Just boiled or steamed cabbage, drained, with no salt, butter, oil, onion, or garlic added. The standard British Sunday-roast cabbage (cooked with butter and pepper) is fine in tiny amounts but ideally cooked separately for the dog.

Nutritional benefits for dogs include vitamin K, vitamin C, and fibre. The fibre helps with mild constipation and feeds beneficial gut bacteria.

Downside: cabbage causes gas. Both raw and cooked cabbage produces sulphur-containing compounds in the gut that make dogs (and humans) gassy. If your dog is already prone to wind, cabbage may make it worse.

How much: a tablespoon or two of cooked plain cabbage for a medium dog, mixed into their regular meal, two or three times a week is plenty.
