Are Candles Safe for Pets? What Every Pet Parent Needs to Know

If you're a pet parent who loves candles, you're not alone. Lighting a candle can instantly make your space feel cozy, calm, and clean. But did you know that many traditional candles can actually pose a risk to your furry friends?

Let’s break it down: are candles really safe for pets?

The Hidden Dangers in Most Candles

Most mainstream candles are made with paraffin wax, bad fragrance oils, and metal-core wicks. Here’s why that matters:

• Paraffin wax is derived from petroleum and can release carcinogenic soot when burned.

• Bad fragrances often contain phthalates and other chemicals that are linked to hormonal disruption and respiratory irritation.

• Lead-core wicks, though now banned in the U.S., may still be found in imported or older candles and can release toxic heavy metals.

For pets who are closer to the ground (where soot and fragrance particles settle) and have smaller respiratory systems, these risks can be even more pronounced.

Signs Your Pet May Be Reacting to a Candle

If your dog or cat is experiencing sneezing, coughing, watery eyes, or even vomiting after you light a candle, that may be a red flag. Some pets are more sensitive than others—especially flat-faced breeds or those with preexisting respiratory issues.

So, Are Any Candles Safe for Pets?

Yes—but you have to know what to look for. Here are a few guidelines for choosing pet-safe candles:

• Wax matters: Look for candles made with soy and coconut waxes.

• Fragrance transparency: Choose brands that disclose their fragrance ingredients and avoid synthetic dyes or chemical preservatives.

• Wick type: Only burn candles with cotton or wood wicks—never metal or unknown blends.
