CAN DOGS EAT CINNAMON?
Cinnamon is not acutely toxic to dogs but can cause mouth and GI irritation, and inhaling cinnamon powder can cause serious respiratory distress. Small amounts in baked goods are unlikely to harm.
Can Dogs Eat Cinnamon?
Why?
Cinnamon is not on the ASPCA's list of acutely toxic foods for dogs, but it is an irritant that can cause several problems in meaningful quantities.
Cassia cinnamon (the most common supermarket variety) contains coumarin at levels much higher than Ceylon cinnamon. Coumarin is hepatotoxic in large amounts and can thin the blood in dogs at high doses. A small amount of cinnamon in a dog treat is unlikely to deliver a hepatotoxic coumarin dose, but regular feeding of cinnamon-heavy food adds up.
The powder is also a respiratory irritant: inhaling cinnamon powder causes choking, coughing, and in significant amounts, can cause respiratory distress and lung inflammation. This is particularly relevant for curious dogs who sniff cinnamon from a jar or bowl.
The safest approach: a trace of cinnamon in a baked treat occasionally is fine. Don't deliberately add cinnamon to food or let dogs sniff or lick cinnamon powder directly.
How much is dangerous?
Not acutely toxic in small amounts. Cassia cinnamon coumarin is hepatotoxic at approximately 1 teaspoon daily for sustained periods.
What are the symptoms?
- mouth and GI irritation, vomiting, diarrhea; respiratory distress if powder inhaled; liver effects from very large regular doses
What should I do?
Trace amounts in food: no action needed. Inhaled cinnamon powder: monitor for respiratory distress, contact vet if breathing is affected.
Frequently asked questions.
Can dogs eat cinnamon rolls?
No — cinnamon rolls contain large amounts of cinnamon, butter, and often raisins, xylitol, or excessive sugar. None of these are safe for dogs.
Is Ceylon cinnamon safer than cassia for dogs?
Ceylon cinnamon contains dramatically less coumarin than cassia. If you're adding cinnamon to dog treats, Ceylon is preferable. But neither should be a regular large addition.
