What Oils Are Harmful To Dogs

Over the past few years, using essential oils has grown like wildfire. Despite being extremely popular, there is few and conflicting scientific evidence regarding the benefits to health. This is especially true when talking about how your pet’s health may be affected.

Numerous essential oils are outright poisonous to animals, including eucalyptus, tea tree, cinnamon, citrus, peppermint, pine, wintergreen, and ylang ylang. These are harmful whether they are licked up after a spill, applied to the skin, or used in diffusers.

Diffusers, which give off a pleasant perfume and may seem harmless, can actually be dangerous since they release minute oil droplets into the air using water vapour. If diffused oils are used in a small area and/or for an extended period of time, it is known that both humans and pets who inhale them can experience respiratory problems.

It’s vital to remember that compared to us, animals like cats and dogs are far more sensitive to smells. A scent that seems inconsequential to you may be overpowering and damaging to an animal.

Is it safe to use oil diffusers around dogs?

You might have recently noticed postings or articles on social media about essential oils, oil diffusers, and the risk they could cause to your dogs. For a very long time, essential oils have been a well-liked at-home treatment for a variety of illnesses, such as nasal congestion, anxiety, painful muscles, and skin disorders. There has been an increase in concern about how these oils may harm indoor animals as a result of the growing popularity of oil diffusers, a convenient way to introduce these oils into your house. The ASPCA Animal Poison Control Center (APCC) therefore seeks to clarify this hot topic.

Are essential oils potentially harmful for your pets? And if so, what precautions should pet parents be taking?

As we frequently see, there is a little more to the response than a straightforward “yes” or “no.”

Essential oils can definitely pose a risk to pets when they are 100% concentrated. Health issues can arise in dogs and cats who have come into contact with oils, walked through them, had some on their coats, or had oils applied directly to them.

These signs include:

  • shakiness when walking
  • Depression
  • decreased body temperature (in severe cases)

If a pet consumes concentrated essential oils, you can also notice sadness, diarrhea, and vomiting in the animal.

Are some oils/scents more dangerous than others?

It’s possible that some oils are more dangerous than others. However, a number of things, like the product’s mix-ins and concentration level, have an impact on this. For instance, whereas another oil may require more or less, concentrated types of tea tree oil (also known as melaleuca oil) may harm your dogs with just seven or eight drops. It is preferable to absolutely avoid applying essential oils to your pet directly due to the wide range in concentration, formulation, and potential quality of these substances. To avoid possible ingestion, you should also keep any oils up and out of the reach of paws.

So, does that mean you should return your diffuser?

The APCC says no, not always. It shouldn’t be a problem to use an oil diffuser for a brief length of time in a safe location that neither your dog nor cat can access.

However, it might be advisable to completely avoid using one if your pet has a history of breathing issues. Remember that your pets’ sense of smell is far more acute than ours, so something that seems light to us could be overwhelming to them.

If you decide to maintain your diffuser, make sure it is placed in a location where your pet cannot knock it over and perhaps come into contact with the oils. Always err on the side of caution and “pet-proof your space” to prevent exposing your pets to harmful toxins.

It is advised to avoid using an essential oil diffuser in your home if you have birds, even though the same issues with essential oils apply to other pets including rabbits, guinea pigs, and hamsters. Because birds’ respiratory systems are so delicate, using a diffuser could cause them to have more severe issues.

Not only do essential oils make our houses smell wonderful, but supporters say the calming aromas may also be able to boost our health and make us feel more focused.

But are our pets safe from these products? The use of essential oils to enhance pet health is still debatable. While some holistic veterinarians and practitioners of alternative medicine may advise using particular essential oils, the majority of veterinary specialists advise pet parents to avoid them. The advantages of essential oils for dogs are, at best, untested. Some essential oils have the potential to seriously jeopardize your pet’s health.

Unfortunately, because our pets frequently can’t metabolize things the way we do, products that are labeled “all natural” or “organic” are not necessarily suitable for dogs and cats. They find it challenging to get rid of some essential oils and other contaminants from their body as a result. If consumed, inhaled, or administered topically to pets, especially in forms that are very concentrated, they can be extremely harmful.

Pet owners should use caution while utilizing essential oils near their animals. Make sure you are aware of safe essential oil usage techniques and which essential oils should never be used. Pets other than dogs and cats are also susceptible to injury from essential oils, including rabbits, hamsters, guinea pigs, and other small animals. Particularly vulnerable to the harmful effects of inhaled oils are birds.

How Essential Oils Affect Dogs and Cats

It’s crucial to understand the fundamentals of how essential oils function in order to keep your pet safe around them. The fatty aromatic chemicals known as essential oils are taken from numerous plants. These substances are extracted through distillation into a variety of concentrations, ranging from 100% pure essential oils to concentrations as low as 1-2%, which are then diluted with a non-aromatic carrier oil. The risk to pets increases as the oil’s concentration increases.

Due to their lipophilic nature, essential oils are easily absorbed through the skin and mucous membranes (including the lining of the mouth and nose), which then transport the oils into the bloodstream where the liver metabolizes and excretes the majority of them.

Essential oils can also be inhaled as fragrances, which can then travel through the nose to the olfactory nerves and the amygdala, where they cause a reaction in the brain’s emotional center. For instance, the aromas of peppermint and lavender might generate feelings of strength and enthusiasm respectively. Numerous individuals utilize essential oils for a variety of potential health advantages, such as regulating sleep, lowering anxiety, and relieving muscle aches and nasal congestion. Some essential oils may also serve as insect repellents in addition to aromatherapy, keeping mosquitoes and other bugs away.

Pure essential oils, air fresheners, room sprays, flavorings, herbal remedies, perfumes, aromatherapy jewelry, bath and personal products, home cleaning products (like Pine-Sol), candles, liquid potpourri, as well as passive or active diffusers are just a few of the many forms that essential oils can take.

Reed diffusers, warmers, and plug-in diffusers are examples of passive diffusers. Essential oil aromas from these diffusers might irritate dogs’ and cats’ respiratory systems. In contrast, active diffusers, such nebulizers or ultrasonic diffusers, release microdroplets of oil that stick to adjacent objects in addition to a scent. Using active diffusers can actually put your pet at risk for an even bigger danger when they consume the oil on their fur while being groomed, in addition to respiratory irritation.

Pet-safe Essential Oils

Most essential oils should be avoided by pet owners, however a handful can be used on animals safely. For instance, the safest essential oil for both dogs and cats is probably lavender (when used sparingly and in the right proportion). Other oils, nevertheless, which are healthy for dogs might not be suitable for cats due to species differences.

When using an oil, it must be properly diluted and applied. Since essential oils’ toxicity is dose-dependent, a product’s potential risk increases as it becomes more concentrated.

Your veterinarian can provide guidance on the proper carrier oils to use for your pet as well as dose and dilution recommendations for various oils (such as coconut oil, extra virgin olive oil, almond oil, and grapeseed oil). For adequate dilution of pet-friendly oils, it is typically necessary to use at least 1 drop of pure essential oil to 50 drops of a pure carrier oil.

Remember that even safe essential oils can irritate the airways when breathed. Before using an essential oil product advertised for pets, such as shampoos, sprays, or relaxing treats, it is always a good idea to consult your veterinarian about its safety.

Additionally, just because an oil is safe for a dog or cat doesn’t mean it will automatically make them healthier. For instance, citrus oils, such as citronella and lemon, can potentially help lessen the severity of flea and tick infestations as well as the prevalence of mosquitoes when applied to repel pests. However, no scientific study has established that these essential oils are completely successful at avoiding mosquito bites or disease-carrying external parasites, particularly not at a level that is safe and non-toxic. As a result, essential oils should never take the place of year-round, monthly flea, tick, and heartworm prevention methods that have been approved by a veterinarian.

Keep These Essential Oils Away from Pets

It’s not a good idea to presume that an essential oil is safe for the pet parent is also safe for the pet when it comes to essential oils. Due to metabolic variations, the same oil that we can consume without experiencing any negative consequences might harm our pets’ respiratory, neurologic, and liver systems in addition to causing GI discomfort and chemical burns to their mouths or esophaguses. In extreme circumstances, death might occur.

Essential oils can have hazardous effects on animals, cats in particular. Cats are particularly susceptible to developing toxicity when oils cling to their skin or fur since they are such meticulous groomers. In such situations, oils concurrently pass the skin barrier, are ingested, and are inhaled into the body, quickly building up to toxic concentrations in the bloodstream. Pet parents should refrain from using oral, topical, and other inhalation oils around cats because felines are deficient in the enzymes that allow the liver to digest many essential oils and eliminate toxins.

Use of essential oils should also be avoided around dogs and cats with liver diseases, elderly pets, puppies and kittens, pregnant or nursing animals, and pets with respiratory diseases (including asthma and bronchitis). Additionally, keep dogs away from such oils in direct dermal contact if they have open wounds or sores because the broken skin may allow for quicker absorption.

The eyes, ears, nose, and genitalia of your pet should not be exposed to essential oils. Applying an essential oil to the ear canal in an effort to treat ear mites, for example, can harm your pet’s skin, nerves, and eardrums. Your veterinarian should handle the ear mite treatment! Furthermore, applying an essential oil topically, such as tea tree oil, to address dermatological disorders like hot spots or skin allergies frequently results in considerably more skin irritability. Any potential benefits are considerably outweighed by the risks.
