Burning essential oils in a burner or diffuser can make a home smell so lovely – something especially appreciated in a home where there is a fur-baby in residence. Whilst there are many oils that are beneficial to us and our dogs, not all essential oils are safe for dogs.
With the rise in popularity of oil burners and diffusers, there have been an increasing number of cases of dogs presenting with adverse reactions. Some pet parents have been confounded as to why their dogs seemed to be confused, unaware of their surroundings, lacking coordination and even sometimes, unsure of who their owners were.

ESSENTIAL OILS YOU CAN USE WITH DOGS
So, now you’ve ruled out any essential oils that are known to be bad for dogs. You might want to know which ones are generally accepted as dog-safe, and even, beneficial to our dogs.
DOG-SAFE ESSENTIAL OILS FOR OIL BURNERS / DIFFUSERS / NEBULISING DIFFUSERS
These essential oils have been used safely with dogs by practitioners for years:
- Carrot Seed
- Cedarwood Atlas
- Chamomile, German
- Chamomile, Roman
- Clary Sage
- Eucalyptus Radiata
- Geranium
- Ginger
- Helichrysum
- Lavender
- Mandarin, Green
- Marjaram, Sweet
- Myrrh
- Niaouli
- Orange, Sweet
- Peppermint
- Ravensare Aromatica
- Rose
- Thyme Chemotypes
- Valerian
Let’s not forget that dogs have highly sensitive olfactory systems compared to us humble humans. If a scent seems strong to us, imagine that smell intensified dozens of times – it’s easy to see why certain scents could be too much for our pups.
So, even when using oils that are considered to be safe, start gently with any new oil – every dog is different and what is OK for some might be uncomfortable for others.
Here are some of the signs that your dog is upset by the essential oil that you’re using: trying to leave the room where the oil burner is; whining; panting; rubbing their face on furniture / carpets.
OIL BURNER – VS – NEBULISING DIFFUSER?
A little note on burning essential oils in burners and diffusers: whilst they will certainly improve the smell, this is not the most effective way to create a therapeutic atmosphere in the home. A nebulising diffuser is much more effective at dispersing essential oils into the air.
I used oil burners for years but found that the water reservoir always ran out before the candle, and it ended up burning a little pool of scorched oils in the bottom of the dish. What’s more, living in England I really don’t need to humidify my home even more – there is plenty of humidity in this country already!
I now have a nebulising diffuser and find it far superior to an oil burner. Firstly, I can program it (it’s electric) so it comes on and off when I want. Also, since it uses no water, it doesn’t humidify the air. It’s small and unobtrusive, and pretty rugged since unlike other nebulisers, it doesn’t have exposed glass parts.
THE BEST COMPACT NEBULISER DIFFUSER
This is exactly the same as the model I have. It’s a fantastic little thing, and so much better than faffing with traditional oil burners
More importantly though, it is more efficient at transporting the essential oil through my home. Burners rely on heat to evaporate essential oils, but this is not as efficient at yielding the oil’s properties as a nebuliser is. A nebuliser has a tiny air pump that ionises the essential oil into the air.
There are some very beautiful nebulisers on the market now, some built with lovely wooden elements and soft lighting.
ESSENTIAL OILS FOR CALMING NERVOUS DOGS
There are many other benefits to using essential oils in the home – not just to get rid of the doggy smell!
If your dog gets nervous during certain events, for instance, when visitors come, during storms or fireworks etc., then using these essential oils can have a calming effect on them and can be used in burners and diffusers.
- Chamomile
- Lavender (Lavendula angustifolia)
- Neroli (Citrus aurantium
- Petitgrain (Citrus aurantium)
- Roman Chamomile (Anthemis nobilis)
- Sweet Marjoram (Origanum marjorana)
- Sweet Orange (Citrus sinensis)
- Valerian (Valeriana officinalis)
- Vetiver (Vetivera zizanoides)
You might be wondering why Petitgrain and Neroli have the same Latin name – they come from the same plant but Petitgrain comes from the leaves and twigs whereas Neroli is from the flowers.
