Short answer

Yes, a teaspoon of dried rosemary in a whole batch of homemade food is safe for a small dog like your Chihuahua. Rosemary is considered non-toxic to dogs and is even used as a natural preservative in many commercial pet foods. The amount that becomes a concern is far larger than typical culinary use, so a pinch or teaspoon for flavoring is perfectly fine. Just make sure the rosemary is well mixed into the food and watch for any individual stomach upset, though that's very unlikely.

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.
