You also have to keep in mind that proper dosage and administration of peppermint oil is of utmost importance.

The blog Experience-Essential-Oils tells us the following: “Most of the problems associated with essential oils whether they are for human or animal use, stem from the fact that people are using perfume grade oils for therapeutic use. Or people simply are NOT using them correctly!”

How to Use Peppermint Oil for Your Dog

Peppermint oil is a great alternative to a number of chemical based treatments that can turn out to be more toxic and harmful in the long run, such as analgesics and pest repellents. Peppermint oil can be used both internally and externally. Keep in mind that I am not a vet, and you should always make sure you consult with your veterinarian before using any kind of essential oil on your dog. Holistic veterinarians are on the rise and they may be best suited to give you the right advice on how to use a specific oil on your pet. Always try to introduce your pet slowly to and essential oil and make sure you give them rest periods from these oils as well.

The manufacturer of essential oils Young Living tells us that the animal’s size affects the amount of oil you should use on them. They provide the following guidelines:

  • “For smaller animals like cats and small dogs, use 3–5 drops. Be sure to dilute 80–90 percent prior to application (for example, for every 1 drop of oil, use 4–5 drops of a diluting agent, such as V-6Vegetable Oil Complex).
  • For larger animals, like large dogs, start with 3–5 drops. Unless otherwise indicated on the product label, dilution is unnecessary.”

Natural News also provides the following recommendations to take in considerations before using peppermint oil on your pets:

  • Dogs cannot tell you what is or is not working. As such, you must closely watch their reactions. Excessive scratching, sniffing, nervousness or whining are all signs to watch for.
  • Always dilute the oils. A common acceptable dilution is 25% of the adult human formula.
  • Giving essential oils internally is not generally recommended.
  • Do not use any oils on medium-large breed puppies under 8 weeks, and small or toy breeds under 10 weeks. Hydrosols are a much better choice.
  • Gradually introduce the oils.
  • What is good for a large dog is not good for a small dog. Size matters, and less is definitely more when working with oils, for animals or humans.
  • Sick, frail, older, or pregnant dogs have special considerations, just as in humans. Do not administer the same dose to them as you would to a healthy animal of the same size.
  • Never use oils near the eyes, mouth, nose, or genital area.

Also remember to always wash your hands after handling essential oils to prevent them from accidentally getting in contact with your eyes or mouth. It’s also important to note that peppermint oil should not be administered to pregnant dogs because of its stimulant properties.

Here are some ways you can use peppermint oil on your dogs:

  • One drop of peppermint oil in their bowl of water will help cool your dog down faster. This also helps when your dog is suffering from hot spots in companionship with cool compresses that can be made out of peppermint leaf tea.
  • You can use a dilution of peppermint oil (3 drops in a half teaspoon of carrier oil) and apply it on the tips of your dog’s ears to ease cramps due to digestive issues. You may also use this and rub it on your dog’s tummy to help the discomfort caused by nausea and/or motion sickness. This can also be used on the outer area of the ear to help ear inflammation due to infection, or to soothe any other areas of pain, making sure you keep away from the face and genital regions.
  • You can make a repellent spray by adding 10 drops in a spray bottle filled with water, or by using a bandana as a makeshift collar and apply a couple of peppermint oil drops on that as well.
  • Adding a few drops of peppermint essential oil to your dog’s shampoo will also help repel fleas and ticks. Make sure it’s a mild shampoo with no harsh ingredients.

Choosing Essential Oils

As I have previously explained, choosing the right essential oil is important because not all of them are created the same. When it comes to personal use or for your dogs, you need to seek the highest quality therapeutic grade essential oils.

The purity of an essential oil is a common issue, and this is because its achievement is expensive. For example, it takes nearly one hundred pounds of lavender plants to produce one pound of Lavandula angustifolia essential oil. Because of this, many producers will dilute essential oils with other carrier oils or even add artificial fragrances to create a greater production. Natural News gives us the following guidelines to make sure you buy the purest therapeutic essential oil:

  • EO’s should not be oily or leave a greasy residue.
  • Packaging should include the common name (i.e. Lavender), the Latin binomial (i.e. Lavandula angustifolia), the country of origin, the method of distillation, the part of the plant used, lot number, amount of oil in bottle, contact information of the company, how the plant was grown, and the words “100% pure essential oil” orthe ingredients, if in a carrier or blend.
  • Price usually dictates quality.
  • Not all bottles of the same size yet of different oils should be priced the same. In other words, if they carry 50 different types of oils, yet every 5ml bottle is $7.40, there is something wrong, and you can guarantee these oils have been adulterated in some way.

Peppermint oil has many beneficial properties for your dog.

  • Are there any side effects in peppermint oil?

The only significant side effects from using peppermint oil stem from the quality and proper usage of the essential oil itself. You need to make sure you have purchased a pure, high quality oil. You can determine this by reading the label closely. High quality oils will not be cheap and will not be diluted with another carrier oil such as jojoba oil. They will also always have the scientific name on the bottle. You should also keep in mind that the dosage is important and that every dog is different. If your dog seems to present an abnormal behavior then he/she might not respond well to peppermint oil or you may have used an improper dosage. Always be sure to check with your vet and to read the instructions on how to properly use peppermint essential oil.

Pure therapeutic grade peppermint oil will be steam distilled and will be guaranteed to not contain any toxic chemicals.

  • How do I use peppermint oil for my dog?

Peppermint oil can be used both internally and externally. For internal uses, you can add a drop to their water to help them with their internal cooling, since dogs have no sweat glands. They’ll also have a fresher breath.

It can aid stomach cramps, dysplasia, arthritis, ear aches, motion sickness, etc. Never apply this oil directly on their face, eyes, nose, or genital regions.

This essential oil is also popularly used in combination with other essential oils to create repellent shampoos and sprays that you can use on your dog and on your dog’s bedding.
