Can Dogs Eat Cabbage? NZ Safety Answer

Quick answer

Dogs can usually have plain cabbage as an occasional food extra if it is washed, unseasoned and cut into manageable pieces. Avoid coleslaw, dressing, onion, garlic, butter and salty leftovers.

Why

SPCA NZ lists cabbage among healthy dog foods that can be incorporated into homemade treat ideas. The NZ risk is usually the serving style: coleslaw, stir-fry, corned-beef sides, buttered cabbage or leftovers with onion, garlic, salt or rich sauces.

If your dog ate it

Contact your NZ vet, after-hours emergency clinic, or SPCA for advice, especially if the food contained a known toxin or your pet seems unwell.

Safer alternatives

Use plain, washed, unseasoned produce in small treat-sized pieces only if your dog already tolerates it. Keep complete dog food as the main diet and skip butter, salt, gravy, onion, garlic and rich sauces.
