Can dogs eat cinnamon? Caution
Not toxic, but not a treat. Cinnamon can irritate a dog's mouth and stomach, and inhaled powder can cause coughing and breathing trouble.
What to do now
- Check the food for xylitol, raisins or nutmeg.
- Watch for vomiting, diarrhea, coughing or trouble breathing.
- Call your vet now if the food had xylitol or raisins, or your dog is struggling to breathe.
Don't
- Don't give cinnamon essential oil; it can be toxic.
How to give it safely
Not needed. A small amount in a plain, dog-safe baked treat is unlikely to cause harm.
Signs to watch for
- Mouth irritation
- Vomiting
- Diarrhea
- Coughing or choking
- Trouble breathing
Why
A little cinnamon in baked goods is unlikely to harm a dog, but large amounts can cause vomiting and diarrhea and affect heart rate and blood sugar. Cinnamon baked goods may also contain xylitol, raisins or nutmeg.
