A spice that we encounter quite often during the winter season is cinnamon. Now that the spice is in almost every pastry, you might wonder if your dog can eat cinnamon and if it might even be healthy for dogs. PETBOOK spoke with veterinarian Dr. Hölter to reveal whether cinnamon is healthy for dogs, when caution is advised, and in which cases cinnamon can even benefit your dog.
Can Dogs Eat Cinnamon?
Yes, dogs can eat cinnamon, but only in small amounts and not in every situation. “Cinnamon can be given in small amounts to help with stomach rumbling and gas,” explains veterinarian Dr. Hölter. “It has antimicrobial and antispasmodic properties, but at the same time stimulates bowel activity and increases saliva and gastric juice production.”
In small doses, cinnamon can ease digestive problems and even have antibacterial effects. But as always with spices, the amount matters.
How Much Cinnamon Is Allowed for Dogs?
Dogs should not eat unlimited amounts of cinnamon. Depending on their size, they tolerate different amounts of the spice. For healthy dogs, the following rule of thumb applies:
- Small dogs: a pinch (0.1-0.5 grams)
- Medium-sized dogs: ¼ teaspoon
- Large dogs: up to ½ teaspoon (about 1.5 to 2 grams)
Larger therapeutic amounts should only be administered under veterinary guidance. Although cinnamon is a natural product, it can cause strong reactions in high doses. Caution is especially advised for large dogs, as they tolerate cinnamon less well due to higher metabolic activity than small dogs. “I would recommend a maximum of a quarter teaspoon for large dogs for a few days. Without veterinary advice, cinnamon should not be fed in larger amounts over a longer period,” says Dr. Hölter.
Why Cinnamon Can Even Be Healthy for Dogs
Why should you give your dog cinnamon at all? There are various reasons for this. Cinnamon has been used in naturopathy for centuries for various purposes and is said to bring many positive benefits, from its effects on the digestive tract to its antibacterial properties. Some effects can also be positive for dogs.
- Digestive support: The antimicrobial and antispasmodic properties can soothe gastrointestinal complaints in your dog. Cinnamon can help, especially with mild gas or stomach rumbling.
- Strong antioxidant effect: Cinnamon contains secondary plant compounds that reduce free radicals–an effect that can also contribute to general cell health in dogs.
- Possible support for diabetes: “Cinnamon can help lower blood sugar levels,” says veterinarian Dr. Hölter. This effect is also scientifically known from human medicine.
- Mild antibacterial effect: Cinnamon can help reduce harmful bacteria in the gut. However, it only works as a support and should not be used as a substitute for medication.
When Cinnamon Can Be Dangerous for Dogs
As many benefits as cinnamon can have for your dog–in some cases, cinnamon is absolutely off-limits. If your dog suffers from any of the following symptoms, you should refrain from experimenting with cinnamon.
- Irritated stomach lining or stomach ulcer: Here, cinnamon can further irritate the lining. “Dogs with irritated stomach lining or ulcers should not receive cinnamon,” warns Dr. Hölter.
- Allergies: As with any plant product, allergic reactions can occur. Signs can include itching, redness, diarrhea, or vomiting.
- Pregnancy: Cinnamon can trigger uterine contractions and should therefore not be given during pregnancy.
Not Suitable for Cats!
If there are also cats in the household, caution is advised. “Cinnamon is rather unsuitable for cats,” says Dr. Hölter. The reason: Their liver breaks down many plant substances much less effectively.
Which Type of Cinnamon Is Better for Dogs?
There are two common types that your dog will enjoy:
- Ceylon cinnamon (Cinnamomum verum)
- Cassia cinnamon (Cinnamomum cassia)
For dogs–as for humans–Ceylon cinnamon is the better choice. Cassia cinnamon contains significantly more coumarin, a natural substance that can cause liver problems in high doses. For occasional, very small amounts, Cassia is not dangerous. However, if you want to feed cinnamon consciously, always choose Ceylon.
Cinnamon in Dog Biscuits and Snacks–Is That Okay?
Many dog bakeries use cinnamon for Christmas cookies or winter treats. This is generally not a problem as long as the amount is small and no sugar or xylitol is included (xylitol is highly toxic to dogs!). The cookies should not be used as a daily snack.
However, your dog should not nibble on cinnamon stars. The almonds they contain are indigestible for dogs. Sugar, which is also often found in Christmas cookies, is harmful to teeth and simply unnecessary.
How Can I Tell If My Dog Can’t Tolerate Cinnamon?
Typical symptoms of intolerance are:
- Vomiting
- Diarrhea
- Excessive drooling
- Restlessness
- Stomach noises
- Irritated skin (rare)
If you notice such signs, you should stop giving cinnamon and contact a veterinarian.

How to Best Feed Cinnamon to Dogs
Cinnamon should never be fed pure, as the fine dust can irritate the mucous membranes. To add it to their diet, you should
- mix it with some plain yogurt
- use it in homemade dog biscuits
- sprinkle it over pumpkin or rice puree
- use it in honey solutions for dogs (once a week)
Basic rule: Start with a low dose and observe how your dog tolerates it.
Conclusion: Can My Dog Eat Cinnamon?
Yes, your dog can eat cinnamon. Feed cinnamon only in moderation, not in every life phase, and never uncontrollably. If you keep this in mind, your dog can also benefit from the numerous positive effects of cinnamon.
