My 4 kg Chihuahua ate half a teaspoon of dried rosemary from the counter — is this amount safe for a small dog?

Short answer

Yes, that small amount is perfectly safe for a dog of any size. Rosemary is non-toxic to dogs and is often used as a natural preservative in commercial pet foods. The main risk with dried herbs is that a very large, concentrated amount might cause mild stomach upset, but half a teaspoon for a 4 kg dog is well within the safe food-amount range. Just offer fresh water, and contact your own vet if you notice any unusual vomiting or diarrhea.

Rosemary — Food safety facts

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

Safe in food amounts. Rosemary extract is a common pet food preservative.

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

Rosemary 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.

Rosemary can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
