Can dogs eat cinnamon?
Why
Cinnamon is not toxic to dogs, but larger quantities can irritate the mouth, throat, and stomach and cause hyperactivity and a fast heart rate. Inhaled powder can cause coughing, breathing trouble, or pneumonia. Cinnamon essential oil is far more concentrated and poses a higher risk than the ground spice.
How much is safe
The small amount found in most baked goods is fine; avoid cinnamon essential oil and large doses.
Warning signs to watch for
Mouth and stomach irritation, upset stomach, elevated heart rate, and coughing if inhaled.
