Is Peppermint Essential Oil Safe for Dogs

Natural remedies don’t always mean safe remedies, especially when it comes to pets. So, is peppermint essential oil safe for dogs? Are there any side effects? 

Before you take any essential oil, either for you or your pet, remember to do your research. Not every natural remedy that is safe for you is safe for your pet as well. Let’s dig deeper and solve all your concerns!

How Much Peppermint Oil Is Toxic to Dogs?

Peppermint toxicity depends on the ingested or inhaled dose and the dog’s weight. Of course, if the poisoning is incidental it is very difficult to predict. 

According to ASPCA, peppermint oil and its main ingredient, mint, are considered toxic to pets. So, the intentional applying of peppermint oil is not the best idea. 

If peppermint oil usage is unavoidable, we advise using a good brand and small doses. This will keep your dog as safe as possible.  

Another tip for keeping your dog safe from ingesting or inhaling peppermint oil is the safe storage of essential oils. Our furry friends tend to explore our kitchens, and finding “forbidden” remedies is not our goal. Therefore, try to keep the peppermint oil as safe as possible. 

Is Diluted Peppermint Oil Safe to Spray Around Dogs?

The main ingredients of the peppermint essential oils are menthol and menthone.

Peppermint oil is considered toxic to dogs, but there are some theories that essential oils can be used as repellents. However, we don’t recommend it since there are many safer alternatives.

Peppermint oil can be diluted and sprayed around dogs. But there is always a possibility for adverse effects due to its toxicity. While some humans report alleviated headaches after inhaling peppermint oil, don’t expect many good effects on your pet.

Tips for Diluting Peppermint Oil

In case of diluting, add only one drop to 50 drops of a safe carrier oil such as coconut or avocado oil. This will create safe dilution for your pet. Our advice is to keep the windows open as soon as you do this. Make sure to keep the door open in case your dog wants to leave the room. 

Believe it or not, there are certified animal aromatherapists that can help you create the proper dose for your dog. Also, it is important to choose the proper peppermint essential oil brand in case you decide to include it for your pet. If you are planning to dilute peppermint oil for your small puppy – abort the mission! Small puppies are anyways sensitive, and adding peppermint essential oil can do more harm than good. 

Can Dogs Be Allergic to Peppermint?

Allergies are very common in dogs, and peppermint essential oil can be one cause for it. Allergies usually occur when the oil is inhaled or ingested. 

If you notice an allergic reaction, you should contact a veterinarian. However, first aid shouldn’t be water rinse since it can do more harm. Try using carrier oil if you have it in your home. If not, visit the closest vet office. 

In humans, allergic contact lip inflammation can lead to some severe effects.
