Cabbage is safe for dogs

Cabbage (green, red, and napa) is safe for dogs and rich in vitamins C and K, fiber, and antioxidants. Red cabbage is especially high in antioxidants. The main issue is gas — cruciferous vegetables cause flatulence. Cooking reduces this. Large amounts of raw cabbage can also affect thyroid function, but this requires very large quantities.

Common Questions

Does cabbage affect dog thyroid?
Cabbage contains thiocyanate, which in very large quantities could hypothetically affect thyroid function. However, a dog would need to eat unrealistic amounts regularly for this to be a concern. Normal treat-sized portions are perfectly safe.
Can dogs eat sauerkraut?
Plain sauerkraut in small amounts can actually be beneficial — it's fermented and contains probiotics. However, many commercial sauerkrauts are high in sodium. Choose low-sodium varieties and feed in moderation.
Is red or green cabbage better for dogs?
Both are safe. Red cabbage has higher levels of anthocyanins (antioxidants) and slightly more vitamin C. Green cabbage is also nutritious. Either is a fine choice.
