Are Essential Oils Safe For Dogs?

With the rise in popularity of natural remedies, many pet parents often wonder if essential oils are safe for dogs. While essential oils can offer a variety of therapeutic benefits for us humans, their effects on dogs can be very different and, in some cases, extremely dangerous.

We will break down which essential oils are safe for dogs, and which can be toxic and how to use these oils properly.

The Appeal of Essential Oils in Pet Households

Essential oils are extracted from plants and used for their aromatic and therapeutic properties. We use different essential oils for many purposes such as in diffusers, massage oils, or even some household cleaning products. Some of us will try out different essential oils to calm anxious dogs, repel pests, or to ease skin irritations. However, dogs process these substances differently from humans, and their heightened sense of smell and unique metabolism can make even a small amount of essential oil dangerous.

It’s important to remember that the phrase "natural" doesn’t automatically mean “safe.” Just like certain essential oils are highly toxic to cats, such as tea tree oil and eucalyptus oil, many of the same oils can also be harmful or even fatal to dogs if used improperly or ingested.

Which Essential Oils Are Toxic to Dogs?

Below is a list of some of the essential oils that are considered toxic to dogs and should be avoided entirely:

Tea Tree Oil (Melaleuca) 

Tea Tree Oil is often promoted for its antibacterial properties, however it is extremely toxic to dogs. Even small doses can cause weakness, tremors, vomiting, and central nervous system depression.

Eucalyptus Oil

Eucalyptus Oil is a popular ingredient in cold remedies and air fresheners; however, eucalyptus oil can cause salivation, vomiting, and lethargy in dogs.

Cinnamon Oil

If your dog ingests or absorbs cinnamon oil, it can lead to liver problems, low blood sugar, vomiting, or even seizures in dogs.

Pennyroyal Oil

Pennyroyal Oil is commonly used as an insect repellent and is extremely toxic to dogs and can cause severe liver damage.

Pine Oil

Pine Oil is found in many cleaning products and can lead to irritation of the skin and mucous membranes, as well as cause your dog to have central nervous system problems.

Citrus Oils (Lemon, Lime, Orange) 

While these may seem harmless, citrus oils can cause your dog to vomit, develop skin irritations, and sensitivity to light.

Wintergreen and Sweet Birch Oils

 Both of these oils contain methyl salicylate, which is highly toxic to dogs and can lead to liver failure.

Even diffusing these oils in a room where your dog spends time can be dangerous, as inhalation alone can lead to respiratory distress or other symptoms, especially in small dogs or those with preexisting conditions.

Are There Any Essential Oils That Are Safe for Dogs?

Yes, a few essential oils are generally considered safe for dogs when used appropriately and in diluted forms. However, it’s always best to consult with your veterinarian before introducing any essential oils into your dog or even cat’s environment.

Some of the safer essential oils for dogs include the following:

Lavender Oil

Lavender oil is often used to reduce anxiety in dogs and is one of the few oils that is generally well-tolerated by dogs.  Lavender oil can promote relaxation and help soothe skin irritations.

Chamomile Oil

Like lavender, chamomile oil has calming properties and may help with your dog’s anxiety and skin inflammation.

Cedarwood Oil

Cedarwood Oil is sometimes used as a natural flea repellent and can be safe for dogs in very diluted forms.

Ginger Oil

Ginger oil may help relieve nausea or car sickness in dogs, though it should only be used under professional guidance.

Frankincense Oil

Known for its anti-inflammatory and immune-boosting properties, frankincense is sometimes used in pet-friendly blends.

Always dilute these oils significantly ideally with a pet-safe oil like fractionated coconut oil and avoid applying directly to your dog’s skin or fur without professional advice. Inhalation exposure should also be minimal, especially in enclosed spaces.

How to Safely Use Essential Oils Around Dogs

When using essential oils in a household with dogs, it’s important to take a cautious and well-informed approach.

Below are some of the best practices:

Avoid Direct Application

Never apply essential oils directly to your dog’s skin or fur unless directed by a vet.

Use a Pet-Safe Diffuser

If you’re diffusing oils, make sure your dog has the ability to leave the room freely. Always diffuse in a well-ventilated space.

Store Oils Securely 

Keep all essential oils out of reach. Dogs are curious and may chew on bottles, risking ingestion or exposure.

Watch for Symptoms

Signs of essential oil toxicity in dogs include vomiting, diarrhea, excessive drooling, weakness, tremors, or difficulty breathing. If you notice any of these symptoms, make sure to go to your veterinary immediately.

Dogs and Cats: A Shared Vulnerability

While it’s widely known that essential oils are toxic to cats due to their liver’s inability to metabolize certain compounds, dogs can suffer from many of the same risks. Their powerful sense of smell and different metabolism mean they’re highly susceptible to toxic reactions. Just because your dog doesn't react immediately doesn't mean the oil is safe, as symptoms can be delayed and sometimes cumulative.

Final Thoughts: Are Essential Oils Safe for Dogs?

So, are essential oils safe for dogs? The answer depends entirely on the type of oil, how it's used, and whether it's properly diluted. Many essential oils are dangerous and should never be used around dogs, while others can be cautiously introduced with expert guidance.

If you're looking for natural remedies for your dog’s anxiety or skin health, it's best to speak to your veterinarian who can recommend safe and effective solutions tailored specifically to your pup.
