Is it bad for dogs to eat cinnamon?

Cinnamon is generally safe for dogs in small amounts, and it can even offer some health benefits, like anti-inflammatory properties. However, large quantities can lead to gastrointestinal upset or other health issues. It's important to ensure that any cinnamon given is plain and free from additives, such as sugar or xylitol, which can be harmful to dogs. Always consult your veterinarian before introducing new foods into your pet's diet.
