Mint leaves may ease your dog’s digestion, but some mint treats can be harmful.

Can Dogs Eat Peppermint?
Peppermint is a popular herb frequently used in snacks, desserts, and health products. Pet owners often wonder if itâs safe to share this aromatic treat with their dogs. This comprehensive guide examines the safety, risks, benefits, and best practices when it comes to offering peppermint to your canine companion.
Is Peppermint Safe for Dogs?
Maybe. Peppermint itself is not toxic to dogs in small quantities, but some forms and related products can be dangerous. The biggest concerns include upset stomach, potential toxicity from additives, and accidental ingestion of related mint species like pennyroyal.
- Fresh/Dried Peppermint Leaves: Generally safe for dogs but may cause gastrointestinal upset in sensitive individuals.
- Peppermint Candy and Products: Often contain xylitol, sugar, chocolate, or pennyroyal oilâall hazardous to dogs.
Peppermint vs. Other Mints
The term âmintâ covers several plant species. Most are safe, except for some specific kinds:
Mint Variety | Safe for Dogs? | Main Issues |
---|---|---|
Peppermint (Mentha piperita) | Generally Yes | May cause stomach upset in excess |
Spearmint | Yes | Safe in small amounts |
Pennyroyal (Mentha pulegium) | No | Toxic; can cause liver failure and death |
Wintergreen | No | Can be mistaken for mint, but is toxic |
Potential Benefits of Peppermint for Dogs
Peppermint is sometimes used in dog treats and foods due to its possible benefits. When used in moderation, fresh or dried peppermint may:
- Freshen breath: Mild improvement in breath odor
- Support digestion: May help, but excessive amounts can have the opposite effect
Note that these benefits are anecdotal and not extensively researched in dogs. Most pet nutritionists suggest that benefits, if any, are mild and must be weighed against the risk of digestive upset.
Dangers and Toxicity Warnings
Not all peppermint-related products are safe for dogs. Key risks include:
- Xylitol: Common in sugar-free candies and gums; deadly to dogs, causing hypoglycemia and liver failure.
- Pennyroyal Oil: Sometimes present in flea powders or essential oils; highly toxic, can lead to vomiting, diarrhea, breathing issues, and even death.
- Chocolate: Often paired with peppermint in candies, but is poisonous for dogs.
- High Sugar: Human peppermint candies are often high in sugar, which can cause obesity and dental problems.
Symptoms of Toxicity
If your dog consumes harmful mint species or products, monitor for symptoms such as:
- Vomiting
- Diarrhea
- Difficulty breathing
- Coughing up blood
- Lethargy or weakness
If these symptoms appear, contact a veterinarian immediately.
Proper Ways to Feed Peppermint to Dogs
If you choose to add peppermint to your dogâs diet, follow these safety guidelines:
- Use fresh or dried peppermint leaves only, and ensure the plant is authentic peppermint or spearmint.
- Feed in small amounts; limit to 1-2 leaves per day, finely chopped in food.
- Monitor for stomach upset when introducing new foods.
- Do not feed peppermint candies, cookies, or products made for humans.
- Wash fresh leaves thoroughly to avoid pesticides.
When To Avoid Peppermint
Avoid giving peppermint to dogs that have shown previous digestive sensitivity or those with liver conditions, and especially avoid any products containing oil or extracts.
- Dogs with food allergies or intolerances
- Puppies or elderly dogs (they may be more sensitive)
- Any dog with history of gastrointestinal distress
- Dogs that have consumed pennyroyal or products containing it
Peppermint in Dog Products
Some commercial dog treats and foods contain peppermint or mint for its breath-freshening properties. These products are specially formulated for dogs and do not contain harmful additives like xylitol or chocolate. Always check labels for ingredients before offering new treats to your dog.
Other Spices Dogs Can Safely Eat
Beyond peppermint, some spices are safe for dogs in moderation:
- Turmeric: May help with inflammation, safe in small amounts.
- Cumin: Sometimes used similarly to turmeric, safe in small doses.
- Spearmint: Another mild mint, safe in small amounts.
Never offer spicy or heavily seasoned foods to dogs (i.e., cayenne, chili powder).
