Essential Oils for Dogs: Which Ones are Safe and Which Ones Are Dangerous?
Are essential oils safe for dogs and cats? Discover which botanical oils are backed by science, which essential oils should be avoided around pets, and how Myco Pet Outdoor uses carefully selected organic ingredients to help make every walk, hike, camping trip, and backyard adventure more enjoyable.
The Science-Backed Guide Every Pet Parent Should Read Before Their Next Outdoor Adventure
One minute your dog is happily exploring a hiking trail.
The next…
They're scratching.
Swatting at mosquitoes.
Rolling in the grass.
Or worse—a tick has hitched a ride home.
If you're like most pet parents, you've probably searched:
- What's the best natural bug repellent for dogs?
- Are essential oils safe for dogs and cats?
- What essential oils repel ticks and mosquitoes?
The answers aren't always straightforward.
Some essential oils have been studied for their natural insect-repelling properties.
Others can be harmful—even toxic—to pets when used incorrectly.
So how do you know which is which?
Let's separate fact from fiction before your next outdoor adventure.
Can Essential Oils Really Help Repel Bugs?
The short answer is:
Yes—but choosing the right oils is essential.
Plants naturally produce aromatic compounds to protect themselves from insects, and researchers have found that some botanical oils may help repel mosquitoes, ticks, fleas, and biting flies.
Among the most commonly studied are:
🌿 Cedarwood
🌸 Geranium
🍃 Eucalyptus
🌱 Lemongrass
These oils contain naturally occurring plant compounds that insects find unpleasant, making them popular ingredients in botanical outdoor sprays. (National Center for Biotechnology Information: https://pmc.ncbi.nlm.nih.gov/articles/PMC3059459/)
Natural Doesn't Always Mean Safe
Here's one of the biggest misconceptions in natural pet care:
If it's natural, it must be safe.
Unfortunately, that's simply not true.
Essential oils are highly concentrated plant extracts.
When used incorrectly—or in their undiluted form—they may cause skin irritation, respiratory irritation, or even toxicity in dogs and cats.
Cats are especially sensitive because they lack certain liver enzymes needed to metabolize many essential oil compounds efficiently. Organizations such as the ASPCA advise avoiding the direct use of concentrated essential oils on pets unless specifically formulated for them. (ASPCA: https://www.aspca.org/news/essentials-essential-oils-around-pets)
This is why formulation matters just as much as ingredient selection.
Essential Oils That May Be Harmful to Pets
Some essential oils are generally not recommended for dogs and cats, particularly in concentrated forms.
These include:
❌ Tea Tree (Melaleuca)
❌ Pennyroyal
❌ Wintergreen
❌ Clove
❌ Cinnamon
❌ Pine
❌ High concentrations of Citrus Oils
These oils have been associated with toxicity or irritation when ingested, inhaled in high concentrations, or applied directly to the skin.
This doesn't mean every product containing these ingredients is automatically unsafe—but it does mean pet parents should choose products specifically formulated for animals rather than using pure essential oils at home.
