Candles And Dogs: A Toxic Relationship?

how bad are candles for dogs

Candles are a popular way to create a cosy atmosphere and cover up unpleasant odours, but they can be harmful to dogs. The main risks are ingestion of the candle wax or wick, burns, and the inhalation of toxic substances. The type of wax, wick, and scent used in candles can all pose health risks to dogs, and dogs with asthma or other breathing difficulties are especially vulnerable. However, there are ways to minimise these risks, such as choosing unscented candles made from natural waxes, using flameless candles, or opting for alternative odour-masking methods.

Toxic chemicals in candles

While candles can add to the ambiance and fragrance of a home, scented candles often contain toxic chemicals that can be harmful to dogs. These chemicals can cause allergic reactions or irritate existing respiratory problems in dogs.

One of the most common toxic chemicals found in candles is paraffin wax, which is made from petrol, oil, or coal. When burned, paraffin releases several toxic substances harmful to both humans and dogs. Another toxic substance to avoid is naphthalene, which is often used in insecticides and pest repellents. Naphthalene breaks down in ways that can affect a dog's lungs and eyes, and animal studies indicate that it causes cancer.

Phthalates, also called plasticizers, are another type of chemical commonly found in candles. They are used to soften plastics and are present in many household products. Research suggests that exposure to phthalates can cause cancer in pets and lead to issues with sexual function, fertility, or development.

In addition to these toxic chemicals, scented candles often contain high concentrations of fragrance chemicals. These chemicals can trigger allergic reactions and respiratory problems in dogs. Lead-core wicks were once common in scented candles, and exposure to lead has been linked to hormone disruption, behavioral problems, and learning disabilities.

To avoid exposing your dog to toxic chemicals, opt for unscented candles made from natural, sustainable materials like beeswax, soy wax, or vegetable wax. These candles burn cleanly and produce far fewer microparticles associated with breathing problems and lung cancer.

Essential oils and fragrances

Some essential oils, such as cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang-ylang, are not safe for dogs if ingested or applied to the skin at full strength. Even if an oil is not outright toxic, such as lavender or chamomile, it can still cause gastrointestinal upset if a dog licks it off their skin. It is important to keep all essential oils well out of reach of dogs and to never apply any essential oil or herbal product directly to their coat.

In addition to ingestion and inhalation, dogs can also experience chemical burns from direct contact with essential oils on their skin. It is recommended to wash it off immediately with mild, unscented soap and water and contact a veterinarian if your dog comes into direct contact with essential oils.

When choosing candles, opt for unscented candles made with vegetable wax, soy, or beeswax, as they are much less likely to be toxic to dogs. Flameless candles, air diffusers, and natural odor neutralizers are also safer alternatives to scented candles when dogs are present.

It is important to remember that dogs have a much more acute sense of smell than humans, so what may be a pleasing scent to you could be uncomfortable for your dog. Always monitor your dog's behavior and look out for any signs of an allergic reaction or respiratory distress when introducing new fragrances into their environment.

Fire and burn hazards

While candles are generally considered safe for dogs, there are some fire and burn hazards to be aware of.

Candles pose a fire hazard and can easily be knocked over by a dog, especially if left unattended. It is important to keep candles out of a dog's reach and to never leave a dog alone in an area with a lit candle. This includes ensuring that candles are placed on a high shelf or surface that a dog cannot access.

Dogs may also accidentally nudge tables or other pieces of furniture where candles are burning, leading to potential burns or fires. It is recommended to keep candles in a well-ventilated room and to always supervise a burning candle, especially when a dog is present.

In addition to the risk of knocking over a candle, curious dogs may come too close to the flame and burn themselves. Some dogs may also be attracted to the scent of the candle and try to ingest the wax, which can cause blockages and toxicity due to harmful chemicals. Ingesting candle wax can also result in an upset stomach or intestinal blockage.

To reduce the risk of fire and burn hazards, it is recommended to opt for flameless candles that operate on batteries or LED lights. These candles provide the same relaxing glow without the risk of an open flame. Additionally, choosing unscented candles made of vegetable wax, soy, or beeswax can reduce the risk of toxic fumes and ingestion of harmful chemicals.

Inhalation, ingestion, skin contact

While candles are generally considered safe for dogs, certain types of candles can be harmful to dogs if inhaled, ingested, or through skin contact.

Inhalation

Scented candles contain essential oils, which are highly concentrated plant extracts. These oils can be toxic if inhaled by dogs in large quantities. The fumes released by burning candles can irritate a dog's eyes, nose, and throat, and cause respiratory issues such as coughing, sneezing, and breathing difficulties.

Ingestion

Ingesting candle wax can cause blockages and toxicity in dogs due to the harmful chemicals present in the wax. Some essential oils, such as tea tree oil, peppermint oil, and eucalyptus oil, can cause serious health issues in dogs if ingested, including vomiting, diarrhoea, and even liver failure.

Skin Contact

Essential oils can also be harmful to dogs if they come into direct contact with their skin. It is difficult to control how much oil is in a candle, and the concentrated oils can cause skin irritation or other adverse reactions.

To minimize the risks associated with candles, it is recommended to opt for unscented candles made from vegetable wax, soy, or beeswax, as these are much safer alternatives to paraffin wax. Keep candles out of the dog's reach and avoid leaving them unattended to prevent accidental burns or ingestion of wax.

Safer alternatives

While candles can be a great way to relax and create a cozy atmosphere, they may pose some risks to dogs. The good news is that there are safer alternatives to ensure both you and your furry friend can enjoy the warmth and ambiance of candles without compromising their health and safety.

One option is to opt for flameless candles, which operate on batteries or LEDs. These candles provide the same relaxing glow without the risk of fire hazards or burns. Flameless candles are a great choice if your dog tends to knock things over or get too close to the flame.

Another alternative is to use air diffusers or fresheners. Diffusers allow you to enjoy various scents while providing your dog with a soothing aromatherapy session. There are many pet-friendly options available on the market, ensuring your home smells pleasant without compromising your dog's health.

Natural odor neutralizers, such as a baking soda solution, can also effectively eliminate odors without introducing new scents. Air purifiers are another excellent option, as they filter and deodorize the air without releasing any fragrances.

When choosing candles, opt for unscented varieties made from vegetable wax, soy, or beeswax. These natural waxes are safer alternatives to paraffin wax, which releases toxic substances harmful to both humans and dogs.

Additionally, be mindful of your dog's access to candles. Keep them out of your dog's reach, and avoid leaving them unattended. Always supervise your dog around candles and provide them with the option to leave the room if they find the scent overwhelming.
