Cinnamon is a common household spice that many of us love, but is it safe for dogs? Let's dive into the details of whether or not pet owners should be sharing cinnamon with their dog as we discuss the following:


What is Cinnamon?

Cinnamon is a spice derived from the inner bark of trees belonging to the genus Cinnamomum


“Cinnamon is a tree or shrub belonging to the genus Cinnamomum, native to Sri Lanka, used for its sweet and pungent taste and various essential oils,” according to the 2011 research by Pittman, S.

It has been used for thousands of years in cooking and traditional medicine due to its aromatic flavor and potential health benefits. 


“Cinnamon is a spice with traditional uses in controlling blood pressure, tumor growth, diabetes, Alzheimer's, and Parkinson's diseases, and has numerous health benefits,” according to the 2017 study by Ribeiro-Santos, R., Andrade, M., Madella, D., Martinazzo, A., Moura, L., Melo, N., & Sanches-Silva, A.

There are two main types of cinnamon: Ceylon cinnamon (often referred to as "true" cinnamon) and Cassia cinnamon, which is more commonly found in grocery stores.


“Confusion between true cinnamon and cassia spices in foods does not pose a health risk, but clinical studies with various Cinnamomum species need better botanical identification to ensure generalizable safety and efficacy data,” according to the 2018 study by Oketch-Rabah, H., Marles, R., & Brinckmann, J.

Is Cinnamon Safe for Dogs?


Yes, in moderation. Cinnamon is generally safe for dogs in small amounts and even offers some health benefits, such as anti-inflammatory and antioxidant properties.


However, it's important to use caution, as large quantities lead to digestive upset, low blood sugar, or even liver disease due to the compound coumarin found in some types of cinnamon, particularly Cassia cinnamon.


It's advisable to use Ceylon cinnamon, which has lower levels of coumarin. 


“Ceylon cinnamon bark has the lowest coumarin content (0.08-0.15 mg g-1) compared to other species of cinnamon, such as cassia (Chinese cinnamon), burmanni (Indonesian cinnamon), and loureiroi (Saigon cinnamon),” according to the 2020 study by Drobac, M., Arsenijević, J., & Kovacevic, N.

Always consult with a veterinarian before introducing any new spice or supplement into

the dog's diet. Avoid cinnamon-flavored foods, especially those containing other harmful ingredients like sugar, chocolate, or xylitol.


What are the Interesting Health Benefits of Cinnamon for Dogs?


The several interesting health benefits of cinnamon for dogs when used in moderation are listed below.

  • Anti-Inflammatory Properties: Cinnamon contains compounds that help reduce inflammation, which are beneficial for dogs with arthritis or other inflammatory conditions.

  • Antioxidant Effects: Rich in antioxidants, cinnamon helps combat oxidative stress, which protects the dog's cells from damage and supports overall health.

  • Regulates Blood Sugar: Cinnamon has been shown to help regulate blood sugar levels, which is useful for dogs with diabetes or those prone to weight gain.

  • Improves Heart Health: By helping to lower blood pressure and cholesterol levels, cinnamon contributes to better heart health in dogs.

  • Supports Digestive Health: Cinnamon aids digestion by reducing gas, nausea, and diarrhea, promoting a healthier digestive system in dogs.

  • Antimicrobial Properties: Cinnamon has natural antimicrobial effects, which help fight off bacteria and fungi, potentially reducing the risk of infections.

Can Dogs Eat Cinnamon-Flavored Foods?


No. Dogs should avoid cinnamon-flavored goods, such as cinnamon rolls, as these often contain ingredients harmful to them, such as sugar, chocolate, or the artificial sweetener xylitol, which is toxic.


While cinnamon itself is generally safe in small amounts, some cinnamon-flavored foods are not good for dogs. Always consult with a veterinarian before introducing any new food or supplement into the dog's routine.

Is Cinnamon Toxic to Dogs?


No, cinnamon is not toxic to dogs when given in small amounts. However, it causes adverse effects if consumed in large quantities.


Small doses of cinnamon are safe and even beneficial for dogs, but excessive amounts lead to digestive upset, low blood sugar, or liver problems due to the compound coumarin found in certain types of cinnamon, like Cassia cinnamon. 


“Cinnamon use as a spice is generally safe, but its medicinal use may be associated with significant adverse effects, particularly gastrointestinal disorders and allergic reactions, and should be clinically monitored,” according to the 2019 study by Hajimonfarednejad, M., Ostovar, M., Raee, M., Hashempur, M., Mayer, J., & Heydari, M.

Always use cinnamon in moderation and consult a veterinarian if unsure about the appropriate amount for the dog.


What are the Potential Risks of Cinnamon for Dogs?

The potential risks of cinnamon for dogs are listed below.

  1. Toxicity in Large Amounts: Consuming large quantities of cinnamon leads to toxicity, causing symptoms like vomiting, diarrhea, and liver damage.

  2. Mouth and Stomach Irritation: Cinnamon irritates a dog's mouth and stomach, leading to discomfort, coughing, and choking.

  3. Allergic Reactions: Some dogs have allergic reactions to cinnamon, resulting in skin irritation, itching, or gastrointestinal issues.

  4. Inhalation Risks: Inhaling powdered cinnamon irritates a dog's lungs and respiratory tract, potentially causing coughing or breathing difficulties.

  5. Interaction with Medications: Cinnamon interacts with certain medications, particularly those affecting blood sugar or clotting, making it important to consult a vet before use.


What Cinnamon Products Are Bad for Dogs?


Cinnamon products that are bad for dogs include cinnamon-flavored baked goods, which often contain harmful ingredients like sugar, chocolate, raisins, or xylitol—an artificial sweetener that is toxic to dogs. 


Cinnamon sticks and essential oils are also problematic; cinnamon sticks pose a choking hazard or cause digestive issues if ingested, while cinnamon oil is highly concentrated and causes skin irritation, respiratory problems, or toxicity if ingested. 


As for the cinnamon scent, it is generally safe for dogs and is enjoyable to some. However, avoid spraying cinnamon directly on the dog, as the concentrated form of cinnamon oil or powder irritates their skin, nose, or eyes. 


“Cinnamon oil can cause local irritant effects on the skin, such as erythema, welts, and mild eye irritation, but no systemic effects were reported,” according to the 1990 study by Perry, P., Bs, D., & Krenzelok, E.  

Are Occasional Cinnamon Treats Safe for Dogs?


Yes, occasional treats with small amounts of cinnamon are safe for most dogs. Just be sure the treat does not contain other harmful ingredients and that the amount of cinnamon is minimal.

How Much Cinnamon is Good for Dogs to Eat?


The amount of cinnamon that is safe for dogs to eat depends on their size, but in general, about 1/8 teaspoon per day for small dogs and up to 1/2 teaspoon for larger dogs is safe. 


It's important to start with smaller amounts and observe how the dog reacts. While small quantities offer health benefits, too much cinnamon leads to adverse effects such as vomiting, diarrhea, low blood sugar, increased heart rate, or liver damage. 


Signs that a dog has consumed too much cinnamon include coughing, difficulty breathing, skin irritation, or a noticeable drop in energy levels. If any of these symptoms occur, contact a veterinarian immediately.


What Are Other Foods that Are Good for Dogs?


Dogs enjoy a variety of human foods in moderation, such as apples, carrots, and plain

cooked chicken. Always research or consult a vet before introducing new foods to ensure they are safe for pets.
