Can dogs eat cauliflower?

Yes — plain, in moderation

Yes. Plain cooked or raw cauliflower is safe for dogs in moderate amounts. May cause gas like other cruciferous vegetables.

The full picture

Cauliflower is a safe, low-calorie vegetable for dogs. It's rich in vitamins C and K, plus fiber. Some dogs eat it raw (crunchy treat), others prefer it steamed. Like broccoli and cabbage, it can cause gas and bloating in larger amounts. Always plain — never with cheese sauce, butter, or garlic. Cauliflower rice made in a food processor with no seasoning is a reasonable low-calorie filler.
