Cinnamon

Can dogs have cinnamon? Yes, in small amounts. The ASPCA lists cinnamon as non-toxic to dogs, cats and horses, and a sprinkle in a homemade treat is not a problem. The risks come from the dose and the form: large amounts of powder, cinnamon essential oil, inhaled powder, and the sugar, xylitol and nutmeg that tend to travel with cinnamon in baked goods.

So the real answer depends on what your pet got into. A lick of cinnamon oatmeal is nothing. A spoonful of powder inhaled off the counter, a cinnamon roll with icing, or a cat walking through diffused cinnamon oil each carry different risks. Here is how to tell them apart.

Is Cinnamon Bad for Dogs?

Not in the amounts found in food. The ASPCA’s plant database lists cinnamon (Cinnamomum zeylanicum) as non-toxic to dogs, cats and horses. That means it is not a poison in the way garlic is. It does not mean unlimited amounts are fine.

According to Pet Poison Helpline, it takes a larger amount of cinnamon powder to cause problems — more than one teaspoon for most pets — but only a small amount of cinnamon essential oil. AKC adds that small-breed dogs may be more sensitive. In large overdoses, the signs Pet Poison Helpline lists are vomiting, diarrhea, low blood sugar, liver disease and changes in heart rate.

How Much Cinnamon Is Too Much?

The one attributable threshold is Pet Poison Helpline’s: more than a teaspoon of powder for most pets. Hill’s quotes a veterinarian describing one teaspoon of powder as a large dose. For a small dog or a cat, the margin is smaller.

In practice, a pinch baked into a batch of dog biscuits or a light dusting on a treat is well below that. Some pet retailers publish serving charts, but there is no nutritional need for cinnamon, so we would not treat it as a daily supplement. If you use it, keep it to an occasional pinch and choose plain cinnamon, not a spice blend.

Forms of Cinnamon, From Safest to Riskiest

Ground cinnamon in food

The small amounts used in cooking and baking are the lowest-risk form. The main hazard is what the cinnamon is mixed into.

Cinnamon sticks

AKC notes that chewing cinnamon sticks can irritate the mouth. Sticks are also a chewing and swallowing hazard for determined dogs, so keep them out of reach.

Loose powder that gets inhaled

Dogs who stick their nose in a spilled jar can inhale fine powder. Pet Poison Helpline lists coughing, choking, difficulty breathing and bronchospasm from direct inhalation. Dogs with airway problems should avoid cinnamon dust entirely.

Cinnamon essential oil

This is the form to take seriously. Oil is far more concentrated than powder, and the Merck Veterinary Manual lists cinnamon oil among essential oils that are potentially toxic to the liver. Never apply it to skin or fur, and keep bottles, reed diffusers and scented cleaning products out of reach.

Cassia vs. Ceylon Cinnamon

There are two main kinds of cinnamon. The ASPCA entry is for Ceylon cinnamon (Cinnamomum zeylanicum). Cassia is a related species with a stronger flavor and more coumarin, a natural compound that can be harmful in large amounts. Several veterinary and pet-nutrition sources describe Ceylon as the better choice for pets for that reason.

For the tiny amounts in a treat, either is unlikely to matter. If you bake for your dog often, Ceylon is the more conservative pick.

Does Cinnamon Have Health Benefits for Dogs?

Most ranking pages list benefits: antioxidants, less inflammation, better blood sugar control. Those claims come mainly from lab and human research. We did not find a controlled study showing cinnamon improves health in dogs, cats or horses, which is why we treat it as a flavor, not a supplement.

One practical point: if your dog is diabetic, do not add cinnamon hoping to steady blood sugar. Anything that might change glucose belongs in a conversation with your vet, not in the treat jar.

Buy Cinnamon From Sources You Trust

This is the point no pet page mentions. In March 2024 the FDA warned consumers about ground cinnamon products with elevated lead, naming six brands with levels of 2.03 to 3.4 parts per million and advising people to stop using and throw them away. It followed the 2023 recall of cinnamon applesauce pouches, where the cinnamon tested between 2,270 and 5,110 ppm. The FDA added another brand in July 2024.

The FDA alerts were written for people, not pets. But lead is lead, and a small dog getting cinnamon treats every week is exposed by body weight to more than you are. Buy from established brands, check the FDA’s list, and do not assume a cheap bulk bag is the same product.

Cinnamon Rolls, Toast Crunch and Other Baked Goods

Most cinnamon-related vet calls are really about the other ingredients.

• Xylitol. Sugar-free baked goods, icings and syrups may contain xylitol, which AKC and Chewy flag as very toxic to dogs. Check labels on anything “sugar-free.”

• Nutmeg. Pumpkin spice and apple pie spice blends usually include it. Nutmeg contains myristicin; Pet Poison Helpline says the small amount in recipes is very unlikely to cause serious toxicity, but large ingestions can cause disorientation, high heart rate and possibly seizures lasting up to 48 hours.

• Raisins and chocolate. Common in cinnamon breads and muffins, and both dangerous to dogs.

• Sugar and fat. Icing, butter and pastry can cause stomach upset and, in dogs prone to it, pancreatitis.

A bite of a plain cinnamon roll is usually just a sugar and fat problem. A whole roll with icing for a small dog, or anything sugar-free, is worth a call. Sugary cereals like Cinnamon Toast Crunch are not toxic, but they are empty calories — skip them. For dog-safe seasonal baking, see our fall dog treat recipes.

Cinnamon Oatmeal, Applesauce and Other Everyday Foods

• Cinnamon oatmeal. Plain cooked oats with a pinch of cinnamon is fine as an occasional treat. Instant flavored packets add sugar and sometimes raisins, so skip those.

• Cinnamon applesauce. A spoonful of plain, unsweetened applesauce is fine. Avoid sweetened versions, check “no sugar added” products for xylitol, and note the 2023 lead recall involved cinnamon applesauce pouches (see the sourcing section above).

• Cinnamon sugar and cinnamon toast. Not toxic, but it is mostly sugar and often butter. A lick is nothing; a habit is empty calories.

• Snickerdoodles and spice cookies. Sugar, butter and sometimes nutmeg. One cookie for a large dog is usually just a stomach risk; check the recipe for xylitol, raisins or chocolate.

Dogs, Cats and Horses

Dogs

Small amounts of ground cinnamon are fine. The practical risks are baked goods, inhaled powder and essential oil. Small breeds and dogs with airway issues get the least margin.

Cats

The ASPCA lists cinnamon as non-toxic to cats, and a cat that licks a dusting of cinnamon is unlikely to have problems. Cinnamon oil is a different matter. The Merck Veterinary Manual explains that cats are deficient in the liver enzyme glucuronyl transferase, which makes them very sensitive to phenols and phenolic compounds found in some essential oils. Pet Poison Helpline lists cinnamon oil among the essential oils toxic to cats, along with tea tree oil, peppermint oil and eucalyptus.

Active diffusers are the hidden risk: they release microdroplets that settle on fur and are swallowed during grooming. If you have cats, skip cinnamon-scented diffusers and potpourri. Our cat safety page covers the wider picture.

Horses

The ASPCA lists cinnamon as non-toxic to horses. It turns up in some equine metabolic supplements, but we did not find controlled equine evidence we would stand behind, so treat those label claims with caution and involve your vet if your horse has a metabolic condition.

Cinnamon Around the House

Food is not the only way pets meet cinnamon. Pet Poison Helpline lists chewing on cinnamon trees kept as indoor ornamentals, cinnamon sticks left in cider cups, and essential oil used for cooking or aromatherapy. Daily Paws adds cinnamon brooms and candles to the list for cats.

• Scented candles and brooms carry cinnamon oil or fragrance. Keep them where cats cannot rub against or chew them, and never leave a lit candle where a tail can reach it.

• Sticks in drinks are easy for a dog to fish out of a mug on the coffee table. Bin them after use.

• Cinnamon as a “natural” deterrent. Scattering powder to keep pets off furniture or out of gardens invites the inhalation problem described above. Choose a physical barrier instead.

Signs Your Pet Had Too Much Cinnamon

• Mouth irritation, drooling or pawing at the mouth

• Vomiting or diarrhea

• Coughing, choking or trouble breathing after inhaling powder

• Weakness or changes in heart rate

• In cats exposed to oil: drooling, vomiting, tremors, wobbliness or breathing difficulty

Can Dogs Be Allergic to Cinnamon?

It is possible. Pet Poison Helpline describes cinnamon as a potent antigen: repeated skin contact can build a sensitivity that shows up as redness, irritation or even blisters where it touched, and this can happen inside a pet’s mouth.

Signs to watch for include itchy skin, hives or a rash, paw licking or chewing, a red mouth, vomiting or diarrhea. If your pet reacts, stop the cinnamon. Facial swelling or any breathing trouble is a same-hour vet visit.

What To Do If Your Pet Ate Cinnamon

• Identify the form and amount. Pinch of powder, a spoonful, a stick, a baked good or essential oil. Check labels for xylitol, nutmeg, raisins or chocolate.

• Small amount of powder in food: usually no action beyond watching for stomach upset.

• More than a teaspoon of powder, any essential oil, anything with xylitol, or any breathing trouble: call your vet, the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply) or Pet Poison Helpline at (855) 764-7661 ($89 per incident).

• Oil on skin or fur: stop a cat from grooming it off and call for advice on cleaning it.

• Do not induce vomiting unless a veterinarian tells you to.

When to Call Your Veterinarian

Right away for breathing difficulty, repeated vomiting, weakness or collapse, and for any cat exposed to cinnamon oil. The same day if a small dog ate a large amount of powder or a baked good that might contain xylitol, nutmeg, raisins or chocolate.

How It Fits With Hemp

Cinnamon and hemp share a use case: both end up in homemade treats. If you bake for your dog, a pinch of Ceylon cinnamon adds flavor, and full-spectrum hemp is best given alongside a meal. If you would rather not bake, our hemp dog treats are ready-made. Hemp is not a remedy for any ingestion — that is always a call to your vet.

Frequently Asked Questions

Can dogs have cinnamon?

Yes, a small amount of ground cinnamon is non-toxic according to the ASPCA. Avoid large amounts of powder, cinnamon oil and cinnamon baked goods.

Is cinnamon safe for dogs every day?

There is no need for it. An occasional pinch in a treat is fine; we would not make it a daily supplement.

Can dogs have cinnamon rolls with icing?

Best not. The icing and pastry are sugar and fat, and sugar-free versions may contain xylitol, which is toxic to dogs. A small bite of a plain roll is usually just an upset-stomach risk; a whole roll for a small dog is worth a call.

Can dogs eat Cinnamon Toast Crunch?

A few pieces will not poison a dog, but it is sugary cereal with no benefit. Skip it.

Can cats have cinnamon?

Ground cinnamon is non-toxic to cats in small amounts. Cinnamon essential oil is the risk, because cats process phenolic compounds poorly.

Is cinnamon oil safe to diffuse around pets?

Not around cats. Diffused oil settles on fur and is swallowed during grooming. For dogs, keep diffusers out of reach and stop if you see coughing or drooling.

Will cinnamon hurt dogs if they sniff it?

Inhaled powder can cause coughing, choking and breathing difficulty. Keep open jars and spills away from curious noses.

Is cinnamon good for dogs?

There is no strong evidence of health benefits in dogs. Treat it as a flavor, not a supplement.

Are dogs allergic to cinnamon?

Some can be. Pet Poison Helpline calls cinnamon a potent antigen that can cause redness and irritation where it touches, including the mouth. Stop if you see itching, hives or mouth redness, and call your vet for facial swelling.

Can dogs eat cinnamon applesauce?

A spoonful of plain, unsweetened applesauce with cinnamon is fine. Skip sweetened versions and check sugar-free ones for xylitol.

Can dogs eat cinnamon oatmeal?

Plain cooked oats with a pinch of cinnamon, yes. Flavored instant packets bring sugar and sometimes raisins, so avoid those.

Can dogs eat snickerdoodle cookies?

Not as a treat. They are sugar and butter, and some recipes include nutmeg. One stolen cookie is usually just an upset-stomach risk for a medium or large dog; check for xylitol or raisins.

Can I use cinnamon to keep my dog or cat off the furniture?

We wouldn’t. Loose powder can be inhaled and cause coughing or choking. A barrier or a covered surface is safer.
