Can a Chihuahua eat rosemary?
✅ Safe
Yes, a pinch of fresh leaves.
How much: A small pinch of chopped fresh rosemary, once or twice a week.
Why
It has antioxidant and antimicrobial properties. Large amounts can be irritating; a pinch added to his food is a flavor many dogs love.
Rosemary in a Chihuahua's diet
Keep in mind how tiny the portions are for this breed: an adult Chihuahua eats roughly 1 to 2.3 ounces (25-65 g) of food a day depending on his weight, and treats shouldn't go over 10% of his daily calories. That's only a small fraction of an ounce. What looks like "a little bite" to us can be half a meal for him.
