Are Scented Candles Safe Around Dogs?

Scented candles are a popular way to make a home feel warm, calm, and inviting. However, if you share your space with a dog, it’s reasonable to wonder whether those pleasant fragrances are actually safe for your furry companion. The short answer is: some scented candles can pose risks to dogs, depending on the ingredients, fragrance type, and how they’re used. Read our Holidays4Dogs article which explores the question of whether scented candles are safe around dogs.

Why Scented Candles Can Be a Problem for Dogs.

Dogs experience the world largely through their sense of smell, which is far more sensitive than a human’s. What smells mild, or pleasant to us, can be overwhelming—or even harmful—to dogs. This means some dogs can find scented candles too over-powering for their sensitive noses.

Fragrance Sensitivity

Many scented candles use synthetic fragrances, or essential oils, that can irritate a dog’s respiratory system. Strong, or continuous exposure, may lead to sneezing, coughing, watery eyes or, agitation (behaviour changes).

Certain essential oils—such as tea tree, eucalyptus, cinnamon, clove, peppermint, and citrus—are especially problematic for dogs when inhaled in concentrated form.

Air Quality.

Paraffin wax candles (made from petroleum by-products) can release soot and volatile organic compounds (VOCs) when burned. As a result, these pollutants may affect both human and canine lungs, but dogs – especially small breeds, seniors, or those with respiratory conditions—are much more vulnerable to the effects of scented candles.

Risk of Accidental Ingestion or Burns

Dogs may knock over candles with their tails or noses, leading to:

  • Burns from hot wax, or flame

  • Fire hazards

  • Ingestion of wax or essential oils if they chew candle remnants

Are There Any Safe Alternatives?

Yes – candles made from natural products like soy or, beeswax, are considered to be safer alternative candle ingredients.

Look for candles that are:

  • Made from soy, beeswax, or coconut wax

  • Unscented or very lightly scented

  • Fragranced with pet-safe essential oils in low concentrations

  • Free from synthetic dyes

Even with these types of natural candle it is better to make sure the room is well ventilated and they are not used for lengthy amounts of time.

Tips :

If you choose to burn candles in a dog-friendly home, consider implementing some of these precautions –

  • Limit burn time (short periods instead of hours)

  • Ventilate the room by opening windows, or using air circulation

  • Keep candles out of reach—never on low tables or floors

  • Avoid burning candles in small or enclosed spaces

  • Watch your dog for reactions, such as coughing, hiding, or restlessness

If you notice any concerning symptoms, extinguish the candle and consult your veterinarian.

Dog-Safe Alternatives.

If you’d rather avoid the risk altogether, here are safer ways to keep your home smelling fresh:

  • Beeswax candles (naturally mild honey scent).

  • Simmer pots with dog-safe ingredients (like apples or rosemary—no citrus or spices).

  • Regular cleaning and ventilation.

  • Pet-safe air purifiers

Final thoughts.

Scented candles aren’t automatically dangerous, but not all candles are dog-safe and most should generally be avoided in our opinion. Strong fragrances, synthetic chemicals, and certain essential oils can negatively affect your dog’s health—especially with frequent, or prolonged exposure.

If you have a dog, choosing cleaner candles, using them sparingly, and paying attention to your pet’s behaviour can help you strike a balance between a cosy home and a safe environment. When in doubt, your dog’s nose knows best 🙂
