What You Need to Know About Dogs and Cinnamon: Safety Guidelines

Your curious pup just got into the kitchen spice rack—should you panic? Here’s the truth about whether dogs can eat cinnamon and when it becomes a real concern.

The Bottom Line: Small Amounts Are Okay, Large Amounts Aren’t

Dogs can eat cinnamon in small quantities without serious harm. According to veterinary toxicologists, less than a teaspoon of powdered cinnamon is considered safe for adult dogs. However, there’s a catch: the type of cinnamon matters significantly.

Cassia cinnamon, the common variety you’ll find in most grocery stores, contains coumarin—a compound that causes problems in large doses. If your dog consumes too much, they may experience vomiting, diarrhea, low blood sugar, liver damage, or abnormal heart rates. Ceylon cinnamon (often labeled “true cinnamon”) is a safer option since it contains minimal coumarin, but it’s also less commonly available and more expensive.

Cinnamon in Different Forms: Not All Are Equal

Cinnamon sticks pose choking risks. While small pieces aren’t toxic, they can irritate the mouth and digestive system—and that’s before considering the choking hazard.

Cinnamon oil and extracts are the real danger. These concentrated forms are toxic to dogs, even in tiny amounts like a few drops. They can cause skin and eye irritation, gut problems, and in severe cases, vomiting, diarrhea, liver disease, and heart rate changes.

Cinnamon-flavored foods require scrutiny. Cinnamon rolls are particularly risky—they’re high in fat and sugar, and may contain raisins or xylitol, both toxic to dogs. Cinnamon sugar, cinnamon toast, and similar treats can lead to obesity and dental issues.

Puppies and Cinnamon: Best Avoided

Puppies’ digestive systems and organ development aren’t fully mature. Even small amounts of cinnamon can cause more harm than good. Stick to complete, balanced puppy food unless your vet recommends otherwise.

Is Cinnamon Actually Healthy for Dogs?

While cinnamon offers antioxidant benefits, veterinarians caution against adding it to your dog’s diet without specific veterinary guidance. The scientific evidence supporting claims about cinnamon improving blood sugar or reducing inflammation in dogs is currently limited.

Better alternatives exist. Dog-safe foods with proven nutritional value include blueberries, carrots, apples (without seeds), bell peppers, strawberries, cantaloupe, cranberries, broccoli, and cucumbers. These are safer, more nutrient-rich options.

What to Do If Your Dog Gets Into Cinnamon

• Small accidental exposure: Usually harmless. A little powdered cinnamon inhalation or a tiny taste typically doesn’t require vet care.
• Large amounts or concentrated forms: Contact your veterinarian immediately.
• Uncertain amounts: Call the Pet Poison Helpline (855-764-7661) or ASPCA Animal Poison Control (888-426-4435). These hotlines have board-certified vets who can assess toxicity levels and recommend treatment. Note that consultation fees may apply.

The Takeaway

Dogs can eat cinnamon safely in minimal amounts, but there’s no compelling reason to include it in their diet. Your dog’s health is better served by proven, nutrient-dense alternatives. Keep cinnamon products out of reach, monitor what your pup gets into, and consult your vet before adding any new ingredients to their food.
