In recent years, essential oils have gained immense popularity for their aromatic and therapeutic properties. From soothing stress to promoting relaxation, these oils have become an integral part of many households.

However, a growing concern has emerged regarding the potential hazards essential oils pose to our furry friends. As responsible pet owners, it’s crucial to understand the potential dangers these oils have on pets.


Many well-intentioned pet owners may unknowingly use essential oils to treat their pets, believing that the natural properties of these oils can provide relief for various health issues. 

However, the lack of awareness about the potential toxicity of certain essential oils can lead to unintended and harmful consequences for pets. 


Misinformation and misconceptions often cloud the discussion surrounding essential oils usage around and on pets. One common myth is that essential oils are natural and therefore, must be safe for animals. 

While it’s true that some natural substances are safe for pets, essential oils are potent and can have adverse effects on our furry companions. 

Another misconception is that if a certain essential oil is safe for one species (humans), it must be safe for all species. The reality is, pets have different physiological and metabolic systems, making their responses and sensitivities distinct from those of humans.


The lack of comprehensive scientific research on the effects of essential oils on pets contributes to the confusion surrounding their safety. Pet owners may rely on anecdotal evidence or information from unreliable sources, leading to misguided decisions.

Some pet owners might turn to essential oils as an alternative to traditional veterinary treatments due to concerns about side effects or a desire for more “natural” options. This desperation to provide relief to a suffering pet can lead them to experiment with essential oils without proper knowledge.

Misinformation about the use of essential oils on pets can spread quickly through social media platforms and on online forums. Peer recommendations, even if well-intended, may not be grounded in scientific understanding.


Several essential oils contain compounds that can be toxic to pets. Phenols, terpenes and phenylpropanoids are common constituents found in many essential oils. These compounds can negatively affect a pet’s liver, nervous system and overall well-being. 

Some of the most highly toxic essential oils to pets, include:

  • Tea Tree (Melaleuca) Oil
  • Peppermint Oil
  • Cinnamon Oil

Cats lack the necessary enzymes to metabolize certain compounds found in essential oils, making them more susceptible to toxicity. Dogs, though more resilient, are also at risk when exposed to undiluted oils or from ingesting them.

Additionally, pets’ heightened sense of smell makes them more sensitive to aromas. Strong scents from essential oils can overwhelm their delicate senses causing distress, anxiety and/or respiratory issues.

Some pets may experience skin irritations, burns and/or allergic reactions when exposed, further underscoring the need for caution.


Identifying essential oil toxicity in pets is crucial for timely intervention. Symptoms may vary depending on the type of oil, the method of exposure, amount of exposure, and the individual pet’s sensitivity.

In addition, applying essential oils to mask symptoms might delay proper diagnosis and treatment by a veterinarian. This delay can exacerbate the underlying health condition and potentially worsen the pet’s overall well-being. 

Common signs of essential oil toxicity include:

  • Difficulty breathing: Rapid breathing, panting, or coughing may indicate respiratory distress due to inhalation of vapors.
  • Drooling and vomiting: Excessive drooling and vomiting can result from ingesting essential oils, either directly or by licking contaminated surfaces.
  • Weakness and lethargy: Essential oil poisoning can lead to weakness, lethargy or a lack of coordination in pets.
  • Skin irritation: Redness, itching or inflammation of the skin may occur upon direct contact.
  • Behavioral changes: Uncharacteristic behaviors, such as restlessness, aggression or depression may indicate a negative reaction to essential oils.


While essential oils can pose risk to pets, responsible usage and careful consideration can minimize these dangers. Here are some guidelines to ensure the safety of your fur babies:

  • Consult your veterinarian: Before introducing essential oils into your home, consult your veterinarian to determine which oils may be safe and appropriate for your specific pet.
  • Dilution is key: Always dilute essential oils before use, as undiluted oils are more likely to cause adverse reactions. Use a carrier oil like coconut or jojoba oil to dilute them properly.
  • Limit exposure: Minimize your pet’s exposure to essential oils by using them in well-ventilated areas for short durations. Avoid using diffusers in rooms where your pets spend most of their time.
  • Avoid direct contact: Prevent direct contact between pets and essential oil bottles, diffusers or any surfaces where oils have been applied.
  • Proper storage: Store essential oils and related products in a secure place inaccessible to pets. Even a small spill or ingestion can have serious consequences.
  • Observe and monitor: Pay close attention to your pet’s behavior after introducing essential oils. If you notice any unusual symptoms, discontinue use immediately and seek veterinary assistance.


The use of essential oils to treat animals without understanding their potential toxicity is a well-intentioned, but misguided practice that can put pets at risk.

It is crucial for pet owners to seek professional advice from their veterinarian before using or exposing an animal to essential oils. Veterinary experts can provide accurate information about the safety and appropriate use of essential oils based on a pet’s specific health needs and individual sensitivities. 

Contact your veterinarian, or the Pet Poison Hotline (1-855-764-7661) immediately, if your pet is exhibiting signs of toxicity from exposure to essential oils.
