Can Dogs Have Cinnamon?

Cinnamon is a widely loved spice whose sweet, warm flavor enhances many human foods. But pet owners often wonder: is cinnamon safe for dogs? The answer is nuanced. While small amounts of cinnamon are generally safe for dogs, excessive intake or the use of certain forms of cinnamon can lead to health problems. Knowing how to feed cinnamon safely is crucial for protecting your dog’s health and well-being .

What Is Cinnamon?

Cinnamon comes from the inner bark of Cinnamomum trees and is available in several forms, including ground powder, sticks, and essential oils. It has long been used for its aromatic qualities and its potential health benefits in human medicine and cuisine .

  • Naturally sugar-free and fat-free
  • Each teaspoon (2 grams) of ground cinnamon has approximately 6 calories, 2 grams of carbohydrates, and 1.4 grams of fiber

Is Cinnamon Safe for Dogs?

Most experts agree cinnamon is not toxic to dogs when given in small quantities. This means you can occasionally sprinkle a modest amount of ground cinnamon on food as a treat. However, safety depends on how much your dog eats, their size, and the type of cinnamon used .

Form of CinnamonSafety for Dogs
Ground Cinnamon (Cassia, Ceylon)Safe in small quantities
Cinnamon SticksShould be avoided (risk of mouth irritation)
Cinnamon Essential OilHighly toxic, should not be used

According to the Pet Poison Helpline, it takes more than one teaspoon of cinnamon powder to cause problems in most pets, but even smaller amounts can affect small dogs or those with existing health issues .

Is Cinnamon Toxic to Dogs?

Cinnamon powder is generally not toxic, but cinnamon essential oil is very toxic for dogs—even in small doses. Reactions to excessive cinnamon include digestive and respiratory distress, mouth irritation, and, in rare cases, serious systemic effects .

  • Dogs with respiratory conditions should avoid cinnamon completely, as inhalation irritates the lungs

Potential Side Effects and Risks of Cinnamon in Dogs

While small amounts are safe, ingesting too much cinnamon—or the wrong form—can lead to health concerns. Watch out for the following symptoms:

  • Digestive upset: Vomiting, diarrhea, and stomach pain
  • Mouth and skin irritation: Discomfort or burning sensations
  • Respiratory issues: Coughing, choking, breathing difficulty (especially after inhaling powder)
  • Liver damage: Extremely rare, but possible with repeated high doses
  • Low blood sugar (hypoglycemia): Can result from very large doses
  • Abnormal heart rate: Rare but associated with toxicity

Small-breed dogs and puppies are more susceptible to side effects from cinnamon than larger dogs .

Forms of Cinnamon: What’s Safe and What’s Not?

Ground Cinnamon

Safe in moderation. It can be sprinkled on food or used in homemade treats. Just keep the amount minimal—usually less than ½ teaspoon for small dogs and up to 1 teaspoon for larger breeds per day, though daily supplementation isn’t necessary .

Cinnamon Sticks

Not recommended. Chewing or ingesting sticks can irritate the mouth and digestive tract. Large pieces can also be a choking hazard .

Cinnamon Essential Oil

Never safe for dogs. Essential oil is extremely potent, can cause toxicity, and should be kept well out of reach of pets. Symptoms of poisoning include vomiting, diarrhea, low blood sugar, and even liver damage .

Do Dogs Get Health Benefits from Cinnamon?

While cinnamon is recognized for supporting certain aspects of human health, there is limited scientific evidence of specific health benefits for dogs. However, some claims—based on laboratory studies and anecdotal reports—suggest possible effects:

  • Anti-inflammatory: May help relieve joint pain and muscle soreness in aging or arthritic pets
  • Antibacterial and antifungal: Can help curb certain pathogens in the digestive tract
  • Powers antioxidants: May neutralize damaging free radicals
  • Supports digestion: Helps reduce nausea, gas, and discomfort
  • Improves insulin sensitivity: Some research indicates cinnamon might help lower glucose levels, of potential use to diabetic dogs
  • Potentially supports heart health: May play a role in controlling blood pressure and supporting a healthy heart
  • Weight management: By regulating appetite, cinnamon may assist overweight or diabetic dogs

Important: Most claims originate from human studies. While anecdotal reports are promising, consult your veterinarian before adding cinnamon as a regular supplement to your dog’s diet .

When Is Cinnamon Dangerous for Dogs?

  • Consuming more than 1 teaspoon of ground cinnamon is risky, especially for small breeds and puppies.
  • Cinnamon in baked goods—like pastries, cookies, or cakes—usually contains lots of sugar, butter, and potentially toxic ingredients (e.g., nutmeg, chocolate, raisins) that are dangerous to dogs .
  • Cinnamon sticks and essential oil should be kept away from dogs at all times .
  • Pets with allergies or respiratory diseases should not be exposed to cinnamon, as powder can irritate the nose, mouth, and airways .

Tips for Diabetic and Overweight Dogs

Research suggests cinnamon may help diabetic dogs by slowing sugar absorption, regulating appetite, and supporting heart health . However, always seek professional guidance before adding cinnamon for medical purposes.

Signs of Cinnamon Toxicity in Dogs
