Can dogs eat cabbage?
The full picture
Cabbage is safe for dogs but is one of the classic gas-producing vegetables. A small amount of plain cooked cabbage adds fiber, vitamins C and K, and antioxidants. Too much causes bloating, flatulence, and loose stools. Raw cabbage is even harder to digest. Red, green, and savoy cabbages are all fine in small amounts; skip sauerkraut and coleslaw (salt, vinegar, mayonnaise, onion). Brussels sprouts and kale are closely related and carry similar cautions.

Common questions
My dog just ate a small amount of cabbage — what should I do?
A small accidental mouthful of cabbage is usually not an emergency, but it depends on your dog's size and what else was involved. Watch for vomiting, diarrhea, lethargy, or unusual behavior over the next 12–24 hours. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 if you see any symptoms or if your dog is small or young.
Why is cabbage risky for dogs?
Cabbage is safe for dogs but is one of the classic gas-producing vegetables. A small amount of plain cooked cabbage adds fiber, vitamins C and K, and antioxidants. Too much causes bloating, flatulence, and loose stools. Raw cabbage is even harder to digest. Red, green, and savoy cabbages are all fine in small amounts; skip sauerkraut and coleslaw (salt, vinegar, mayonnaise, onion).
What's a safer alternative to cabbage?
See the alternatives section above. In general, plain cooked meat (no seasoning), plain vegetables like carrot or green bean, or dog-specific treats are always a safer choice than human foods with uncertain risk profiles.
Can cabbage make a dog sick long-term?
Repeated small exposures to cabbage can be worse than a single large accident, depending on the specific risk. Some foods cause cumulative damage (like onion/garlic affecting red blood cells over days), while others just cause repeat GI upset. If your dog has eaten cabbage multiple times, mention it to your vet at the next visit.
