Can dogs eat cinnamon?
Short answer
Yes, a small amount of cinnamon is generally safe for dogs, and some sources suggest it may even have a mild positive effect on blood sugar. In larger amounts, or as a pure powder that gets inhaled, it irritates the airways and digestive tract, so use it sparingly.
Cinnamon is not toxic to dogs, but in large amounts or as an inhaled powder it irritates the mucous membranes and can cause digestive upset. Here is a safe amount, how to use cinnamon if you want to, and when to avoid it.
Why only in moderation
A small amount of cinnamon, like a pinch in a homemade treat, is not toxic to dogs. It contains cinnamaldehyde, an essential oil compound that irritates mucous membranes in concentrated form, but that effect does not show up at typical kitchen quantities.
The bigger risk is a dog inhaling or licking up a large amount of pure cinnamon powder at once, say, from an open bag. The powder irritates the airways and can cause coughing, choking, and irritation of the mouth and throat. This scenario, sometimes called the 'cinnamon challenge,' is documented in people and can cause similar problems in dogs.
Cinnamon essential oil is much more concentrated than ground cinnamon and can irritate the skin, mucous membranes, or liver at higher doses. Essential oils in general should not be given to dogs, orally or on the skin, without checking with a vet first.
Cassia cinnamon, the cheaper, more widely available type, contains more coumarin than true Ceylon cinnamon. Coumarin stresses the liver in large amounts, but the quantity found in typical kitchen use is negligible for an occasional treat.
How to serve cinnamon
- Use just a pinch of ground cinnamon to flavor homemade treats made from oats or pumpkin.
- Never let your dog lick cinnamon powder straight from a spoon or an open bag; there is a risk of inhalation.
- Do not use cinnamon oil or essential oil on the coat or in food without checking with your vet first.
- Watch for any mouth irritation or digestive upset after the first dose, and skip cinnamon if you see either.
Rough portion
A pinch (up to 1/4 teaspoon) of ground cinnamon in a treat now and then is fine for a healthy dog. Pure powder or essential oil should never be given directly.
Risks
- Airway irritation if a large amount of powder is inhaled.
- Irritation of the mouth, throat, and stomach at higher doses.
- Cassia cinnamon contains more coumarin, which stresses the liver in large amounts.
- Cinnamon oil can irritate the skin or mucous membranes.
Symptoms to watch for
- Coughing, breathlessness after inhaling powder
- Drooling, licking at the mouth
- Vomiting or diarrhea after a larger amount
- Skin irritation from contact with the oil
Your dog already ate cinnamon. What now?
- If your dog licked a pinch of cinnamon off a treat, no action is needed.
- If they inhaled or ate a larger amount of pure powder, watch for coughing and breathlessness, and contact your vet if breathing trouble develops.
- Wipe your dog's mouth with lukewarm water if powder is stuck to their nose or lips, so they do not keep licking it.
- See a vet for persistent vomiting, diarrhea, or airway irritation.
Common questions about dogs and cinnamon
Can I give my dog homemade cinnamon treats?
Yes, a small amount of ground cinnamon in homemade treats is safe for dogs. Just make sure the recipe does not include other risky ingredients like chocolate, raisins, or xylitol, which often turn up in baked goods.
Does cinnamon help dogs with diabetes?
Some studies in people suggest a mild effect on insulin sensitivity, but there is not enough data in dogs to recommend it as a treatment. Treat a diabetic dog according to your vet's guidance, and consider cinnamon only as a supplement after checking with them.
Is it dangerous if my dog licks an open bag of cinnamon?
It can be, if they inhale a large amount of powder at once, there is a risk of coughing, breathlessness, and airway irritation. Watch your dog closely and contact your vet if breathing problems appear. Keep cinnamon bags stored out of reach.
Is Ceylon cinnamon safer than regular cassia cinnamon?
Yes, Ceylon cinnamon contains significantly less coumarin, a compound that stresses the liver in large amounts. For occasional pinch-sized use, the difference is barely noticeable; for more frequent use, Ceylon is the safer choice.
Other good treats
Can dogs eat apples?
Yes, dogs can eat apples. The flesh is safe, full of fiber and vitamin C, and even gives teeth a light mechanical clean. Always remove the core and seeds, though, and don't feed large pieces at once.
Can dogs eat bananas?
Yes, dogs can eat banana, but only as an occasional treat. It's safe and dogs tend to love it, but it's high in sugar. A small dog only needs 2 to 3 slices, a large dog about half a banana.
Can dogs eat carrots?
Yes, carrots are safe for dogs and rank among the best treats you can give them. They're low in calories, full of fiber and beta-carotene, and raw carrots even help clean teeth. Cut them to a size that suits your dog.
Can dogs eat pumpkin?
Yes, cooked or plain pumpkin flesh is very healthy for dogs, and vets often recommend it to help with digestive upset. Always choose plain pumpkin puree, never pie filling with added sugar and spices.
More from herbs and spices
Can dogs eat ginger?
Yes, a small amount of fresh or ground ginger is safe for dogs, and it's sometimes even used to help with mild nausea or motion sickness. In large amounts it can irritate the stomach, so keep servings small.
Can dogs eat salt?
No, dogs should not get salt added to their regular diet. They need a small amount of sodium, but complete dog food already provides enough. Added salt, salty foods, or even salt water can cause salt poisoning, which is fatal in severe cases.
