Candles are a popular way to create a cosy atmosphere, but are they harmful to dogs? The short answer is: it depends. While candles are generally considered safe for dogs, certain types of candles can be harmful to dogs if ingested or inhaled. The main concerns are the presence of toxic substances in the wax and the release of fumes and smoke when burned. Some candles contain paraffin wax, synthetic fragrances, and essential oils that can be toxic to dogs if ingested or inhaled. These toxins can irritate a dog's eyes, nose, and throat and cause respiratory issues such as coughing, sneezing, and breathing difficulties. In some cases, toxic candles can lead to more severe health issues, including liver failure and increased cancer risk. However, not all candles are harmful to dogs, and there are dog-friendly options available.
| Characteristics | Values |
|---|---|
| Toxicity | Essential oils and synthetic fragrances in candles are toxic to dogs if ingested, inhaled, or if they come into contact with their skin. Common toxic essential oils include tea tree oil, lavender oil, eucalyptus oil, and peppermint oil. |
| Health Risks | Exposure to toxic candles can cause vomiting, diarrhea, respiratory issues (coughing, sneezing), eye irritation, and even liver failure in dogs. |
| Safe Alternatives | Unscented candles or those made with vegetable wax, soy, coconut, or beeswax are safer alternatives. Candles with lavender essential oil can reduce stress and increase rest in dogs. |
| Precautions | Keep candles out of a dog's reach to prevent accidental ingestion or burns. Avoid leaving candles unattended. Use candles in well-ventilated areas. |

Candles with paraffin wax, synthetic oils, and fragrances can be toxic to dogs
Candles can pose a health risk to dogs, especially those containing paraffin wax, synthetic oils, and fragrances. Paraffin wax candles are made from petroleum, a non-renewable source, and can release carcinogens when burned, which can be harmful to dogs. While most common candle waxes, such as soy, paraffin, and beeswax, are generally considered non-toxic to dogs, ingesting large amounts can cause digestive issues and constipation.
Essential oils and synthetic fragrances in candles can be highly toxic to dogs, especially if ingested, inhaled, or if they come into contact with the dog's skin. These oils are often highly concentrated plant extracts, and certain types, such as tea tree oil, eucalyptus oil, and peppermint oil, can cause serious health issues in dogs, including vomiting, diarrhoea, and even liver failure if ingested. The strong sense of smell of dogs, with up to 300 million olfactory receptors, makes them extremely sensitive to faint smells, and the chemicals in scented candles can have an amplified effect on their respiratory health.
Additionally, candles with synthetic fragrances may contain phthalates, which are used to soften plastics and are known to be toxic to pets. Phthalates are often listed as "fragrances" on product labels, and exposure to them has been linked to cancer, sexual dysfunction, fertility issues, and developmental problems in pets. It is important to choose candles with natural fragrances or opt for unscented candles, which are less likely to contain harmful synthetic fragrances.
To ensure the safety of dogs around candles, it is recommended to opt for candles made from vegetable wax, soy, or beeswax, which are considered safer alternatives to paraffin wax. It is also crucial to keep candles out of the dog's reach to prevent accidental ingestion or burns. Always monitor your dog's health and behaviour, and if any negative symptoms occur, such as watery eyes, sneezing, coughing, or digestive issues, extinguish the candle, move your dog to fresh air, and seek veterinary advice if necessary.

Candles made with vegetable wax, soy, or beeswax are safer alternatives
Candles can be harmful to dogs due to the presence of certain essential oils that are not dog-friendly. These oils can be toxic if ingested, inhaled, or if they come into contact with a dog's skin. Additionally, 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.
To ensure the safety of your dog, opt for candles made with vegetable wax, soy, or beeswax. These candles are safer alternatives to paraffin wax candles, which can contain harmful toxins. Soy-based candles, in particular, are the softest and pose the least amount of risk if ingested. However, it is still important to keep these candles out of your dog's reach, as ingesting large chunks of wax may cause digestive issues.
When choosing scented candles, avoid those with essential oils such as tea tree oil, lavender oil, peppermint oil, and eucalyptus oil, as these can be toxic to dogs and cause serious health issues such as vomiting, diarrhoea, and even liver failure if ingested. Instead, look for candles with dog-safe essential oils like lavender, which has been associated with reduced stress and increased relaxation in dogs.
It is also good practice to never leave candles unattended, especially when you have a dog. Dogs are curious and may accidentally nudge or knock over a burning candle, leading to burns or other accidents. Always ensure candles are placed in a safe location, out of your dog's reach, and blow them out before leaving the room.
By taking these precautions and choosing safer alternatives, you can enjoy the warm glow of candles while keeping your furry friend safe and healthy.

Dogs can have allergic reactions or respiratory issues due to candle fumes
Dogs have a powerful sense of smell, with up to 300 million olfactory receptors compared to 6 million in humans. This means that dogs can be extremely sensitive to faint smells, and certain chemicals in scented candles can have an amplified effect on them.
Candles can be dangerous for dogs because they contain essential oils, which are highly concentrated plant extracts. These oils can be toxic if ingested, inhaled, or if they come into contact with a dog's skin. Some essential oils, like tea tree oil, peppermint oil, and eucalyptus oil, can cause serious health issues in dogs, including vomiting, diarrhoea, and even liver failure if ingested.
In addition to essential oils, candles may be mixed with other ingredients that are toxic to dogs. Burning candles can also release fumes that can be harmful to a dog's respiratory system if inhaled in large quantities. This can lead to irritation of the eyes, nose, and throat, and cause respiratory issues such as coughing, sneezing, and breathing difficulties.
Some signs that your dog may be negatively affected by candle fumes include watery eyes, sneezing, and coughing. If you notice any of these symptoms, blow out the candle and move your dog to fresh air. If your dog experiences more severe symptoms, take them to the vet immediately, as they may be experiencing essential oil poisoning.
To minimize the risk of harming your dog, opt for candles without essential oils if you plan to burn them around your dog. Unscented candles are much less likely to be toxic to dogs. It is also good practice to keep candles out of your dog's reach and to avoid leaving them unattended, as dogs may accidentally nudge furniture with burning candles or ingest candle wax.

Ingesting candle wax may cause digestive issues and, in large amounts, blockages
While candles can create a cosy atmosphere, they can be harmful to dogs if ingested or inhaled. Ingesting candle wax may cause digestive issues and, in large amounts, blockages.
If your dog ingests candle wax, carefully monitor its health and behaviour until the wax passes through. Call your vet if you notice any symptoms of illness, such as vomiting or diarrhoea. While wax is not poisonous to dogs, it can lead to constipation. To remedy this, add canned pumpkin to your dog's food. For smaller dogs, add a teaspoon of canned pumpkin, and for larger dogs, add a tablespoon. If your dog has not had a bowel movement after two days, contact your vet.
If your dog has swallowed a large chunk of wax, it may struggle to digest it. In this case, call your vet immediately. If your dog has also swallowed the candle's wick or any metal parts, this could be particularly harmful, so seek veterinary advice.
To prevent your dog from ingesting candle wax, store candles safely out of reach, ideally in a drawer or a high-up location.

Some candles contain toxic essential oils like tea tree, peppermint, and eucalyptus
Candles can be dangerous for dogs, especially scented candles, as they may contain toxic essential oils. Tea tree oil, peppermint oil, and eucalyptus oil are toxic to dogs and can cause serious health issues such as vomiting, diarrhoea, and even liver failure if ingested. Other essential oils like lavender oil are also harmful to dogs. Therefore, it is important to check the ingredients of a candle before burning it in the presence of dogs.
Essential oils are highly concentrated substances made from the most fragrant parts of plants. They are often toxic to dogs due to their high concentration. In addition, essential oils in candles may be mixed with other toxic ingredients. For example, tea tree oil, which is toxic to dogs, is commonly found in candles. Similarly, candles with peppermint oil can be harmful to dogs.
Eucalyptus oil is another common candle ingredient that is toxic to dogs. Inhaling eucalyptus oil can irritate a dog's eyes, nose, and throat, and cause respiratory issues such as coughing, sneezing, and breathing difficulties. Ingesting eucalyptus oil can also lead to vomiting and diarrhoea.
While candles made with vegetable wax, soy, or beeswax are generally safer alternatives to paraffin wax, it is still important to keep candles out of a dog's reach. Dogs may accidentally knock over a candle, causing burns or wax ingestion. Ingesting candle wax can lead to digestive discomfort and, in large amounts, may cause constipation or diarrhoea.
To ensure the safety of dogs, it is recommended to opt for candles without essential oils or to choose dog-friendly scents like lavender, which has been associated with reduced stress and increased rest in dogs. It is also important to provide proper ventilation when burning candles around dogs and to give them the option to leave the room if they do not like the scent.
