Essential Oils for Pets: What Works and What to AvoidReading Time: 13 minutes
If you’ve fallen in love with essential oils for yourself and your family, you may have wondered if they can be safe and effective for your pets as well. The answer is yes – but only if administered in the right way and if you avoid certain essential oils that may be harmful to them. Here is an introduction on how to use essential oils for pets to enhance the health of your four-legged family members.
Essential Oils and Pets: 5 Key Considerations Before Using Essential Oils With Your Dog or Cat
Before we dive into what essential oils are considered safe for pets in specific situations, here are some overarching guidelines for using essential oils with your furry friends:
#1 – Remember that your pet is “wired for smell.”
According to research from Alabama A & M University and others, humans have about 5 million olfactory receptors in our nasal passages, which are microscopic proteins that allow us to detect odors. That sounds like a lot, but this number pales in comparison to how many your dog has.
A dog has anywhere from 149 million to 300 million, which makes their sense of smell 10,000 to 100,00 times more acute than a human’s sense of smell.
To put it into perspective, while you might be able to detect a teaspoon of sugar in your cup of morning coffee (if you’re awake enough), Fido can detect that same amount of sugar in the equivalent of two Olympic-sized pools worth of coffee.
Your pooch’s sense of smell is very sensitive so take it slow when introducing a new essential oil.
The same guidelines apply with other domestic animals. Although dogs rule the roost when it comes to their sniffers, cats have up to 80 million receptors while rabbits have about 100 million. According to David Whitaker, PhD, of Middle Tennessee State University’s Horse Science Center, “Horses depend on their sense of smell the way we depend on language.”
If your main goal is to eventually use an oil topically or internally (only under vet guidance) with a pet, you may consider wearing a small amount of the essential oil yourself first and allowing your pet to get used to it by simply being around you.
Another method to gauge their reaction is to let your pet sniff the bottles with the covers firmly closed. Some experts even recommend letting your pet “choose” what oils they’re attracted to. Many different oils will usually work to accomplish the same goal. Therefore, you can set out 3 to 5 different appropriate oils on the floor (spread apart) and allow your pet to sniff the closed bottles and “select” the one they’re most interested in.
If you diffuse essential oils in your home, make sure your pet isn’t trapped in a room with the diffuser with no way to get away from the smell.
#2 – Keep your pet’s size in mind.
This may seem like common sense, but it’s worth stating. Remember that essential oils are powerful concentrations of plant essences. A little goes a long way – especially when used on animals and dilution is incredibly important.
Essential oil particles (also called esters) are so small that they can be absorbed into the bloodstream with equal potency whether inhaled, ingested, or applied topically. Once in there, they work quickly on the body and brain.
Pet animals (usually) have much smaller bodies than humans, so proceed slowly and cautiously so you don’t overwhelm their senses. The smaller the animal, the more diluted an oil will need to be.
#3 – Keep it all-natural.
Don’t expose your four-legged family members to harmful chemicals that may do them more harm than good. These days you simply can’t assume that because an essential oil product says “all-natural,” that it’s chemical-free.
Read labels carefully. A truly natural essential oil will usually say “food grade,” “supplement grade,” or “100% organic” somewhere on the packaging. If you’re not sure, check out the company’s website or contact them directly.
If you’re still not convinced that the oil is of the highest quality and purity, it’s best not to use it. (Hint: If you purchased the essential oil at a grocery store, drug store, or gas station, chances are it isn’t the quality you should be using for health purposes.)
Fragrance oils and fragrances in products like air fresheners are harmful to your pet. Your precious pets can’t tell you they don’t like the products you’re using around them, so you need to pay attention to their needs and reactions.
#4 – Don’t use essential oils with pregnant, nursing, or baby animals.
Unless you’re working with someone qualified who can properly advise you, the safest bet is just to avoid using essential oils with any animal under 8-12 weeks as well as pregnant and lactating mothers.
- #5 – Cats are more sensitive than dogs to essential oils, so be extra cautious.
It’s difficult to make blanket statements about essential oils for “pets” because cats have some extra considerations even beyond those for dogs.
For example, many holistic vets recommend avoiding citrus oils and certain kinds of cedar essential oils with cats. Yet these oils are often included in DIY flea treatment recipes for dogs. “Warming oils” such as cinnamon are also usually NOT recommended for cats.
If you have both a cat and dog in your home you may need to limit what oils you use with your dog to accommodate your cat’s sensitivities.
Tea Tree Oil for Dogs & Other Pets: A Little is Beneficial. A Lot Can Be Deadly.
As mentioned above, a small amount of the right essential oil may be beneficial for your pet but too much may cause harm. This is especially the case with tea tree oil (also known as melaleuca).
While tea tree oil is safe for most adult humans, it can be downright lethal for pets if used undiluted.
A 2014 report published in the Journal of the American Veterinary Medical Association analyzed case studies obtained by U.S. Poison Control Centers over a 10-year period.
In close to 350 dogs and over 100 cats who were exposed to 100% (meaning undiluted) melaleuca essential oil, 77% developed toxicity-related reactions. Symptoms included weakness, lack of coordination, muscle tremors, drooling, depression, skin rashes, elevated enzyme levels in the liver and, in some cases, vomiting and coma. Smaller animals such as cats and kittens were most affected.
That being said, holistic vet experts such as Dr. Karen Becker, owner of Natural Pet Animal Care in Chicago, support that a VERY WEAK dilution of 0.1% to 1.0% strength* (diluted in water) of tea tree can be safely used on dogs to treat skin irritations or “hot spots,” wounds, infections, and even drug and environmental allergies. An important note that tea tree oil dilutions should be given to animals as a topical only, never orally.
*For reference, a 1.0% dilution is basically one (1) drop of essential oil in one (1) teaspoon of carrier oil or water. Therefore for a 0.1% dilution, you would use one (1) drop of essential oil to ten (10) teaspoons of carrier oil/water.
Using Safe Essential Oils Topically With Your Pets
Experts also state that for the topical use of safe essential oils for pets, very small animals like small dogs, cats, and rabbits can start out with 3 to 5 drops of DILUTED essential oil at a 0.25% dilution rate.
As an example of how to get a 0.25% dilution, you would mix 4 teaspoons of carrier oil and one (1) drop of essential oil together. You would then use a maximum of 3-5 drops of that diluted mixture with your pet. Again, this is ONLY with essential oils considered safe for pets.
If you’re unsure whether a dosage or a particular oil is safe for your pet, please connect with a local holistic veterinarian or qualified aromatherapist who can guide you. The American Holistic Veterinary Medical Association has a “Find a Vet” link on their website that can help you track down a holistic vet in your area.
Good Carrier Oils to Use With Pets
When you’re diluting essential oils there are many different oils that can be used. Some goods carrier oils to use with pets for topical application include:
- Avocado oil
- Virgin coconut oil (cold pressed) – fractionated is fine
- Extra virgin olive oil
- Jojoba oil
- Flaxseed oil
- Wheat germ oil
- Sesame oil
- Castor oil
Essential Oils for Pet Problems
Now that you know what to watch out for when it comes to your pets and essential oils, when might you consider using essential oils for pets? Below is a listing of some common pet health conditions that often benefit from essential oils.
Ticks & Fleas
Ticks and fleas are probably the most widespread concern for spreading certain kinds of diseases and also for just being downright annoying for humans and pets alike. Many pet owners are also concerned with the toxicity levels of commercial flea & tick collars, topicals, and pills.
This concern is founded on a stark reality: many of the top flea- and tick-killing brands contain carcinogens and chemicals that can affect the nervous system.
You can make your own natural flea & tick repellents for your dog and cat using safe, high-quality essential oils for pets. Rosemary, lavender, and peppermint essential oils are popular in DIY recipes for dogs – both for their fresh small, as well as the ability to help to repel fleas.
There are a variety of recipes available online – just be sure you’re getting your information from a reputable site and using high-quality oils. Also, remember the tip above to pay special attention to oils used with cats.
We already mentioned that small, very heavily diluted amounts of tea tree may do the trick with dogs, but there are other essential oils that can also calm hot spots. For example, small amounts of yarrow (especially from deep blue flowers), can help with these conditions. It can also stop bleeding for minor cuts and scrapes, such as trimming a nail too much into the quick, since it acts as an anti-inflammatory.
According to Janet Roark, DVM (aka “The Essential Oil Vet”), frankincense “helps soothe skin that is irritated, itchy or damaged, particularly when used in conjunction with lavender. It also relaxes and soothes sore muscles and joints in older animals.”
Ever had a cat that wouldn’t go into the cat cage no matter how much cajoling you did? Diffusing a little lavender essential oil may do the trick! Linalool and linalyl acetate are the terpenes (plant chemicals) in lavender that are most responsible for its calming effect on mammalian nervous systems.
Of course, cats are unique creatures and there are felines that absolutely detest lavender. If you have a lavender-hating cat, never try and force the issue.
For cats and dogs that seem amenable to it, you can use 100% organic lavender essential oil in a cold-mist diffuser in your home an hour or so before you’re ready to go or apply a tiny amount (again, heavily diluted in a carrier oil as stated above) on the back of the neck. Lavender is also great for dogs and cats who get jittery before traveling in general.
Confusion – For Dogs Only
For dogs that have moved homes a lot, need to learn new information, or are getting a little confused, diffusing lemon essential oil is uplifting and clarifying. It is also reported to help increase trust in others, which can be helpful if you’re introducing a new family member.
Lemon oil is also an antiviral, antifungal, and antiseptic agent which makes it great for helping to clean the air in homes. Reminder: Lemon oil is a citrus oil and should not be given to cats topically or orally.
Immune System Support
Frankincense oil has been known to boost immune system function. Take caution when using frankincense on pets, however. A tiny amount of diluted oil is all that is needed. You may wish to increase your dilution rate and get the guidance of your vet before using this potent essential oil.

Closing Points to Consider When it Comes to Using Essential Oils With Pets
Just like the human body, the bodies of dogs, cats, and other pets contain innate healing mechanisms within. When given a chance, the body will naturally move towards balance and potential healing.
Using essential oils responsibly and conservatively can, in many cases, help bring an animal’s body back into balance without the potential side-effects of pharmaceutical drugs.
For people who are afraid of using essential oils with and around pets based on stories they’ve read on social media, rest assured that most toxicity or adverse events are the result of gross misuse and overdosage situations (i.e., full undiluted applications).
Melissa Shelton, DVM, and author of Animal Desk Reference: Essential Oils for Animals offered this advice in response to a viral Facebook post about a cat dying after being exposed to essential oils.
So often, essential oils are the obvious thing to blame when an animal all of a sudden appears ill. And the internet is an easy way to find support of this theory. However, in true clinical evaluation, I often find very poor cause and effect relationships. With the vast number of people using essential oils in their home, we can be quick to get into a trap of blaming any illness upon the presence of essential oils. And this, we need to be careful to avoid.
I have consulted with many veterinarians who missed the true diagnosis for weeks, due to the assumption that the essential oils were at the root cause. While I will never say essential oils cannot hurt an animal, we also need to be realistic that when a Facebook post is shared over half a million times, all to animal loving people – the statistics are in the favor of someone also having an animal that falls sick at the time of reading it.https://londonalternativevet.com/2018/01/12/essential-oils-with-pets-dr-melissa-shelton/
