My 8 kg Shih Tzu ate about half a bowl of lamb stew that had oregano in it — is that safe?

Short answer

Yes, that amount of oregano in a cooked dish is perfectly safe for your dog. Oregano used as a seasoning in cooking is not toxic to dogs, and the small quantities found in a stew or sauce are harmless. The real concern with a rich dish like lamb stew is usually the high fat content, not the herbs. Just keep an eye on your dog for any signs of an upset stomach, like vomiting or diarrhea, and call your own vet if anything seems off.

Oregano — Food safety facts

Safe to share · Dogs · full breakdown on the linked food page

Safe in the small amounts used in cooking. Concentrated essential oil is not.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Oregano is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
