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.
If your dog ate more than a safe amount
For a small accidental taste, watch for vomiting, diarrhoea, or signs of discomfort over the next few hours. For a large amount or if your dog is small or has existing health conditions, call your vet. When in doubt, call the ASPCA Animal Poison Control Center on (888) 426-4435.

Does size or breed matter?
No specific toxicity concern from cabbage itself at any size — this is mainly a portion and preparation question. Always serve plain and cooked or chopped small where relevant, since whole or large raw pieces are a bigger choking risk for small and toy breeds than for large dogs. Introduce any new vegetable gradually, as too much fibre too quickly can cause loose stools regardless of the dog's size.
