Are Scented Candles Making Your Dog Sick? 5 Warning Signs to Watch

Scented candles create a warm and inviting ambiance in our homes, but have you ever wondered if they could be harming your furry friend? Are scented candles bad for dogs? Many pet owners unknowingly expose their pets to potentially harmful chemicals that can trigger adverse reactions.

If you've noticed unusual symptoms in your dog, it might be time to reconsider the candles you're burning. In this guide, we'll explore the warning signs that scented candles may be making your dog sick and how to ensure a pet-safe environment.

How Scented Candles Can Affect Dogs

Dogs have an extraordinary sense of smell—up to 100,000 times stronger than humans—which means that even mild fragrances for us can be overwhelming for them. Certain ingredients in scented candles, such as synthetic fragrances, paraffin wax, and essential oils, may irritate your pet’s respiratory system or lead to toxicity.

Warning Signs That Scented Candles Are Affecting Your Dog

1. Respiratory Distress

If your dog starts coughing, sneezing, or wheezing after you light a scented candle, it could be due to volatile organic compounds (VOCs) released into the air. Paraffin wax candles, in particular, emit pollutants like benzene and toluene, which can trigger breathing issues (source).

Signs to Watch For:

• Frequent sneezing or coughing
• Labored breathing or panting
• Watery or irritated eyes
• Runny nose or nasal discharge

2. Allergic Reactions

Just like humans, dogs can develop allergic reactions to certain fragrances or chemicals found in scented candles.

Common Symptoms:

• Excessive itching or scratching
• Skin redness or irritation
• Hives or rashes
• Swelling of the face or paws

If you notice your dog rubbing its face against furniture or scratching excessively after exposure to a scented candle, it might be experiencing an allergic reaction.

3. Lethargy and Unusual Behavior

Exposure to strong synthetic fragrances can affect a dog’s central nervous system, causing them to act unusually sluggish or disoriented.

Symptoms Include:

• Lack of interest in play or walks
• Sleeping more than usual
• Acting disoriented or confused
• Hiding or avoiding certain rooms

4. Digestive Issues from Ingestion

Dogs are curious creatures, and they might be tempted to lick or chew on a candle. This can lead to gastrointestinal problems, especially if the candle contains harmful additives, essential oils, or artificial dyes.

Symptoms of Toxic Ingestion:

• Vomiting or diarrhea
• Loss of appetite
• Excessive drooling
• Stomach pain or bloating

If you suspect your dog has ingested any part of a scented candle, contact your veterinarian immediately.

5. Increased Anxiety or Restlessness

Certain strong or unfamiliar scents can trigger anxiety in dogs. A fragrance that seems calming to you might be overwhelming or distressing to your pet.

Signs of Anxiety:

• Pacing or excessive panting
• Whining or barking without reason
• Hiding or avoiding specific areas
• Restlessness and difficulty settling down

How to Make Your Home Pet-Safe

If you love scented candles but want to ensure a safe environment for your pet, consider these alternatives:

• Choose Pet-Safe Candles – Opt for soy, beeswax, or coconut wax candles with natural, pet-friendly scents like chamomile or vanilla.
• Avoid Toxic Essential Oils – Some oils, including tea tree, eucalyptus, and cinnamon, are harmful to dogs. Check ingredient lists carefully (source).
• Improve Ventilation – Always burn candles in well-ventilated areas to reduce the concentration of airborne irritants.
• Use Flameless Alternatives – Consider essential oil diffusers (with pet-safe oils), simmer pots, or natural air fresheners to keep your home smelling fresh.

Final Thoughts

While scented candles can create a cozy atmosphere, it's essential to be mindful of how they may affect your dog. If you've noticed any warning signs mentioned above, consider switching to pet-friendly alternatives or eliminating scented candles.

Your dog’s health and comfort should always come first. By making informed choices, you can enjoy a beautifully scented home without compromising your pet’s well-being.
