15 Essential Oils that are Toxic to Dogs - Essential Oil Nerd (1)

Dogs are Sensitive

I bet you’ve seen some movies where a heroic dog tracks down a missing kid or finds drugs in a suitcase at the airport, thanks to the dog’s keen sense of smell.

While humans have six million olfactory receptors, dogs supposedly have 300 million olfactory receptors in their noses. And it’s possible they can smell somewhere between 10,000 to 100,000 times better than us mere mortals!

Essential oils need to be used with caution around dogs because dogs are much more sensitive to scent and to essential oils than humans.

The Research

According to Pet MD, there’s a lack of scientific research studying the effects of specific essential oils on cats and dogs.

Additionally, to date, Pet MD reports that there are no studies specifically testing pure essential oils on flea and tick infestations for dogs.

There’s a large number of products for dogs that contain some concentration of essential oil.

However, according to the American Kennel Club, most cases of toxicity in dogs occurred when natural flea and tick repellents containing certain essential oils were used (or misused).

A 2012 study described adverse reactions from natural flea products containing essential oils:

“Dogs and cats can experience significant adverse effects when exposed to plant-derived flea preventatives even when used according to label directions. The number of reports of exposure in cats was higher than dogs, but the frequency of reported adverse effects was similar between the 2 species. Agitation and hypersalivation were common in cats, whereas lethargy and vomiting were common in dogs.”

Symptoms of Harm or Toxicity

Whether you’re using essential oil products on yourself or for your dog, keep in mind that any oil can be harmful if it’s not properly diluted or used incorrectly.

In its pure, undiluted and concentrated form, essential oils can cause harmful reactions for animals, just like it can cause reactions in humans.

When using products containing essential oil, a few factors determine its effect on your dog. These include the type of oil, concentration level of the oil, and additional ingredients mixed with the oils which can cause varying reactions.

Topical or oral exposure can cause any of the following reactions:

  • Skin irritation–e.g. itchiness, burning, sloughing
  • Respiratory irritation–e.g. panting, coughing, wheezing. If your dog has underlying respiratory conditions such as asthma or allergies, certain essential oils can also exacerbate those conditions.
  • GI upset–e.g. vomiting, diarrhea
  • Other potentially severe, less common symptoms also include gait unsteadiness, depression, lethargy, weakness, ulcers, hypothermia, rear leg paralysis, seizures,

In rare cases, if the oil is absorbed into the bloodstream, liver and kidney damage can occur.

Eucalyptus and Peppermint

There’s a lot of conflicting information about eucalyptus and peppermint essential oils.

(Video) Is it ok to use Essential Oils for your pets ? - The Basics

If you scour the internet, you’ll often find both oils to be on the safe or dangerous lists, depending on the source of information.

According to Dr. Callum Turner, DVM, eucalyptus can be considered toxic if ingested and used topically (on the skin), whether it’s directly applied or diluted.

If used in a diffuser, extreme caution should be used (see diffuser tips below).

Another oil that appears controversial for use around dogs is peppermint essential oil.

Certified aromatherapists are more likely to place it on their “safe” list, while animal hospitals seem more likely to place it on the “unsafe” list.

I kept peppermint essential oil on the “unsafe” list in this post because a number of veterinarians place it in that category.

However, I do want to link to this article that examines the issue and may provide the reasoning behind the inclusion of peppermint in the “safe” category on other lists around the internet.

The article advises many safety precautions and promotes careful, cautious use to take advantage of the therapeutic properties of peppermint essential oil.

(Video) How To Safely & Effectively Diffuse Essential Oils Around Your Pets

Can you diffuse essential oils around dogs?

We all want to diffuse our favorite oils, but is it safe for your dog?

The American Society for the Prevention of Cruelty to Animals (ASCPA) Animal Poison Control Center (APCC)specifically addressed this question, stating:

“Using an oil diffuser for a short time period in a secured area— one that your dog or cat cannot access—is not likely to be an issue.”

Aspca animal poison control center

The APCC also advises to make sure the area is secure so that your dog can’t knock over the diffuser, lick it, or drink it.

Additionally, the room should be well ventilated and have an exit to allow your dog to go into a different area or room in your home..

However, if your dog has breathing problems due to underlying health conditions, allergies or asthma, you may want to avoid using diffusers.

Also, be mindful that dogs that walk through oils that are being diffused can have oil land on their fur and may lick their coat, causing unsafe oral ingestion.

Tips to keep your dog safe around essential oils

  1. Always dilute oils! Avoid high concentrations of the oil.
  2. Examine the labels of your dog products containing any essential oils to ensure they are formulated specifically for dogs. Some products may contain an oil on the unsafe list but have proper dilution with very low concentration which may then make it safe for use.
  3. Consider avoiding diffuser use if your dog has an underlying medical condition, especially if it’s respiratory in nature.
  4. Secure all diffusers. Make sure that your dog can’t knock any over or accidentally lick it or ingest oils from it.
  5. If diffusing, allow your dog to leave the area–don’t shut the dog in an enclosed space with the diffuser without a way out. Make sure the area is well-ventilated.
  6. Observe your dog’s behaviors–does he/she show displeasure or act weird after an initial exposure? Leave the room immediately? Show any symptoms, even mild, of possible harm or toxicity?
