Can chihuahuas get sick from eating peanut butter?

No, peanut butter is not toxic to chihuahuas. However, some chihuahuas may be allergic to peanuts, so it is important to introduce peanut butter to your chihuahua in small amounts and monitor for any adverse reactions. Additionally, peanut butter is high in fat and calories, so it should be given to chihuahuas in moderation.
