Dogs can have catnip, and it is generally safe for them in moderation. Unlike cats, which often become hyperactive or playful when exposed to catnip, dogs typically experience a calming or sedative effect. However, giving dogs too much catnip can lead to gastrointestinal issues such as upset stomach, vomiting, or diarrhea. Catnip does not produce the same euphoric response in dogs as it does in cats, and while some dogs may show no reaction, others might become more relaxed after consuming it. It is also important to avoid giving dogs catnip toys designed for cats to prevent choking hazards. Consulting a veterinarian before introducing catnip to a dog's diet is recommended to ensure it is appropriate for the dog's individual health needs.
