Catnip is completely safe for dogs, according to The Nest. Many dogs enjoy the taste of catnip. Catnip is a natural herb that is used to help alleviate issues such as sleeplessness, menstrual cramps and digestive discomfort in dogs.
Catnip can also be used to alleviate stress and nervousness in dogs, according to Pet Adviser. Dogs can consume catnip plain, or owners can sprinkle it over dog food. Owners can also add a few leaves of catnip to water for dogs. However, dogs should not play with cat toys that contain catnip because the toys are often too small and easy to swallow.
