Candle Aromas: Are They Safe For Dogs?

are the essential oils in a candle harmful to dogs

Scented candles are popular for creating a cozy atmosphere, but they can be dangerous for dogs due to the presence of essential oils. These oils are highly concentrated plant extracts that can be toxic to dogs if ingested, inhaled, or absorbed through the skin. The combustion of scented candles releases toxins into the air, and since dogs have a more acute sense of smell, they are susceptible to the effects of smoke and fragrance sensitivity, which can cause respiratory issues. The type of oil, its concentration, and the delivery method determine the risk to your dog's health. Some essential oils, like tea tree, peppermint, and eucalyptus, are known to be harmful to dogs and can cause serious health issues if ingested, while others, like lavender, chamomile, and ginger oils, are used for therapeutic purposes. It is important to carefully select dog-friendly candles or opt for unscented candles made from vegetable wax, soy, or beeswax, which are safer alternatives.

Toxicity and poison risks

Candles can be toxic to dogs, and the essential oils in candles pose a poisoning risk. Dogs have a much stronger sense of smell than humans, with a dog's sense of smell being 10,000–100,000 times more powerful than a human's. This means that fragrances can easily overwhelm dogs and lead to toxicity.

Essential oils are highly concentrated plant extracts, and some are toxic to dogs if ingested, inhaled, or if they come into contact with a dog's skin. Tea tree oil, peppermint oil, and eucalyptus oil can cause serious health issues in dogs, including vomiting, diarrhoea, and even liver failure if ingested. Burning candles release fumes that can be harmful to a dog's respiratory system, leading to irritation of the eyes, nose, and throat, and causing respiratory issues such as coughing, sneezing, and breathing difficulties.

The combustion reaction of burning candles releases toxins into the air, which can negatively affect dogs. Candles made with paraffin, a cheap candle wax, release toxic substances harmful to dogs when burned. These include formaldehyde, acetaldehyde, and acrolein.

However, not all essential oils are toxic to dogs, and some are even used for therapeutic purposes, such as lavender, chamomile, and ginger oils. It is important to consult a veterinarian before using any oils around dogs. To reduce the risk of toxicity and poisoning, it is recommended to use unscented candles or candles made with vegetable wax, soy, or beeswax, as these are safer alternatives to paraffin wax.

Inhalation, ingestion, and skin contact dangers

While candles can be a great way to create a cozy atmosphere, some scented candles contain essential oils that can be harmful to dogs if inhaled, ingested, or if they come into contact with their skin. Dogs have a much stronger sense of smell than humans, with estimates ranging from 10,000 to 100,000 times more powerful. This means that fragrances that seem mild to humans can easily overwhelm a dog and lead to toxicity.

Inhalation dangers:

The combustion of scented candles releases toxins into the air, which can be harmful to dogs. Smoke from candles can cause respiratory issues in dogs, such as coughing, sneezing, and breathing difficulties. Dogs with pre-existing respiratory conditions, such as asthma or allergies, are especially susceptible to these issues.

Ingestion dangers:

Essential oils can be toxic if ingested by dogs, leading to digestive upset, neurological problems, and even liver failure in severe cases. Some common oils, such as tea tree oil, peppermint oil, and eucalyptus oil, are particularly dangerous and can cause vomiting and diarrhea. Ingesting candle wax can also be harmful, as it may contain toxic substances or cause blockages.

Skin contact dangers:

Essential oils can irritate a dog's sensitive skin. Even if the oil is safe for human skin, it may not be safe for dogs due to their inability to properly metabolize certain oils.

To minimize these dangers, it is recommended to use unscented candles or candles made with vegetable wax, soy, or beeswax, which are less likely to be toxic. Certified pet-safe candles that use diluted essential oils are also an option. Always ensure that candles are placed out of a dog's reach and are never left unattended to prevent accidental burns or ingestion.

Paraffin wax concerns

Paraffin wax is a common ingredient in commercial candles due to its low cost of production. However, concerns have been raised about its potential health risks. Paraffin wax is derived from petroleum, coal, or shale oil, and as a result, it contains known carcinogens, such as benzene. Studies have shown that burning paraffin wax candles emit toxic toluene and benzene, which can cause damage to the central nervous system, resulting in headaches, nausea, dizziness, and insomnia.

The combustion of paraffin wax releases toxins into the air, which can lead to negative side effects for both humans and dogs. In fact, researchers at South Carolina State University found that melting paraffin wax candles released harmful chemicals, including toluene and benzene. These chemicals are also present in vehicle exhausts and cigarette smoke.

Some people have reported experiencing headaches, nausea, and asthma attacks when burning paraffin wax candles. The strong scent of paraffin wax may be a contributing factor to these symptoms. However, it is important to note that not all studies have found significant differences in emissions between paraffin wax and other types of wax, such as soy wax.

While fully refined paraffin wax is highly purified and non-toxic, the concerns about paraffin wax may be valid for less refined varieties. Slack and scale wax, for example, are less refined waxes that should not be used for candle-making. Paraffin wax also has environmental implications, as it is a byproduct of gas and oil refineries.

As an alternative to paraffin wax, candle manufacturers and consumers can consider vegetable waxes, such as soy and coconut wax, or beeswax. These natural options are considered safer for both human and animal health.

Fire hazards

Candles pose a fire hazard to dogs, especially when left unattended. Dogs are curious and playful, and they may accidentally knock over a lit candle with their paws or nudge a table or furniture where a candle is burning, causing a fire. This risk is heightened if the dog is left alone in a room with a lit candle.

To reduce the fire hazard, it is recommended to keep candles out of a dog's reach. Place candles on high surfaces that the dog cannot access or bump into. It is also important to be physically present and supervise the dog when burning a candle.

In addition to the fire hazard, candles can also pose other risks to dogs. Some candles contain harmful ingredients and toxic essential oils that can be dangerous if ingested, inhaled, or if they come into contact with a dog's skin. Paraffin wax, for example, releases toxic substances that are harmful to both dogs and humans. Essential oils such as tea tree oil, peppermint oil, and eucalyptus oil can cause serious health issues in dogs, including vomiting, diarrhoea, and even liver failure if ingested.

To minimize these risks, it is advisable to choose candles made from natural, pet-safe ingredients. Unscented candles or those made from soy, beeswax, or vegetable wax are safer options. If using scented candles, ensure they are made with dog-safe essential oils, such as lavender, which has been associated with reduced stress and increased rest in dogs.

Safe alternatives

While candles can help create a cozy atmosphere, some may contain harmful ingredients and toxic essential oils that are unsafe for dogs. To avoid this, opt for candles made from natural waxes like soy, coconut, or beeswax, which burn cleaner and produce fewer harmful byproducts than traditional paraffin candles. These natural waxes are eco-friendlier and healthier options.

If you prefer scented candles, choose those fragranced with pure essential oils or safe synthetic fragrances to avoid harmful chemicals. Essential oils are derived from plants and are a natural alternative to artificial fragrances, which may contain hazardous substances. However, not all essential oils are safe for dogs, so always check the ingredients label and consult a veterinarian before use.

As an alternative to candles, you can use a reed diffuser, which offers a longer-lasting fragrance. Reed diffusers typically consist of a vessel filled with fragrance oil and reeds that soak up and disperse the scent. You can also use candle warmers or essential oil diffusers, which allow you to create your own fragrance blends. Smart diffusers, like the PURA Smart Device, enable you to control fragrance intensity and schedule set hours for usage.

Remember, it's important to keep candles and other fragrance sources out of your dog's reach to prevent accidental burns or ingestion of harmful substances.
