Small amounts of ground cinnamon are generally considered safe for dogs. However, large quantities, especially of cassia cinnamon which contains coumarin, can lead to health issues. Ingesting cinnamon powder directly can also cause respiratory irritation.
How It Affects dogs
Coumarin, found in cassia cinnamon, can be hepatotoxic (liver toxic) in large doses. Inhaling powdered cinnamon can cause respiratory irritation.
