Neem oil is an extract taken from the seeds of the neem tree (Azadirachta indica) native to India. It’s been used for decades as a natural insecticide and skin soother, but is it something you can use on your dog?

While neem oil may be beneficial for pups, there are limits to what it can achieve. Read on to learn more about this oil, including the risks and safety information you need to know before using it on your pet.dogster paw divider

What Is Neem Oil?

Neem oil is a naturally occurring pesticide found in neem tree seeds. It has been used for many years to control pests like aphids and mites, though it is also commonly used in traditional Chinese and Ayurvedic medicine to treat a variety of conditions.

Neem oil is rich in fatty acids that support healthy skin, so it’s also sometimes found in skincare product lines. It also contains plant compounds called limonoids, a type of triterpenes, which have antioxidant, antibacterial and anti-inflammatory effects, and are toxic to insects. Neem oil’s antimicrobial and antiparasitic properties are said to help treat certain conditions in dogs. One study found that the topical treatment with the oil is beneficial for dogs with atopic dermatitis.1

Most vets advise against using neem oil as the only repellent, though it can be used in conjunction with more conventional preventatives. A study on sand fleas in people showed that a neem oil mixture killed only 40% of fleas, which is a much lower success rate than commercial flea preventative products.2

How Is Neem Oil Given?

Neem oil should only be applied topically (to the skin) and should never be ingested. It needs to be diluted prior to application, and then it can be applied to areas where parasites are most likely to occur, including the ears, tail, flanks, and head.

If using neem oil as a repellent, it’s generally recommended to use it in conjunction with other conventional preventatives. We don’t recommend using neem oil as a sole preventative, due to concerns around efficacy and vector-borne diseases.

If using the oil to treat skin irritation, the diluted mix can be applied directly to the area of irritation once your veterinary team has given you the go-ahead. Never use this product to open wounds or sores.

Neem oil can also be added to your dog’s shampoo; however, adding the oil prematurely may break it down and make it inactive. Instead, mix it into the shampoo right before you plan on applying it.

What Happens If You Miss a Dose?

Luckily, neem oil is not like medication, where you must take it at the same time every day, so there are no “doses” to miss. You don’t need to use neem oil daily unless your veterinarian has determined it will be beneficial for your dog’s skin condition or useful in preventing ticks and parasites.

Potential Side Effects of Neem Oil

When diluted properly, neem oil is typically considered a safe substance; however, we always recommend speaking with your veterinarian before opting to treat your pet yourself. Neem oil may interact with some medications. Additionally, some dogs may be sensitive or even allergic to it.

Side effects are more likely if concentrated neem oil is used, your dog ingests some of it, or your dog is sensitive to the effects of neem oil. The following side effects may occur with the use of neem oil:

  • Irritation to the skin surface or eyes
  • Excessive salivation
  • Changes in appetite
  • Vomiting
  • Lethargy
  • Diarrhea
  • Tremors
  • Convulsions
  • Termination of pregnancy

dogster paw dividerFrequently Asked Questions (FAQ)

How do you choose the best neem oil?

Neem oil is easy to find in tinctures, sprays, and shampoos, but it’s important to remember that not all products are created equal. Unfortunately, these types of products aren’t typically regulated, so buying from unreliable sources may mean the ingredients are questionable.

Look for organic, cold-pressed options that are free of additives and preservatives. Consider the concentration of the neem oil in each product. Where possible, use products marketed towards dogs and scour the ingredient list to ensure everything else is pet-friendly.

Can I make my oil neem oil treatment?

You can try making your own neem oil solution at home; however, your final product mustn’t contain more than 1% neem oil. Use a dilution ratio of 1:10 part neem oil with a carrier oil like olive or almond. We recommend testing a small area on your dog before using your homemade remedies to treat the inflamed areas to ensure no allergic reaction occurs.

Please note that homemade concoctions should be prepared directly before you plan to use them. The oil will become less potent over time. It is also essential that you speak to your vet before making and applying a homemade neem oil treatment.

Is there anything to consider before using neem oil?

As mentioned above, neem oil has an extremely strong scent, which can be off-putting to dogs and their owners alike. This odor may linger on your furniture and other belongings if you let your pup interact with it while the solution soaks into their skin fur.

Conclusion

While neem oil is reliably used for repelling and killing certain parasites, vets do not recommend using it as your dog’s only line of defense. Use other preventative measures in addition to the oil to ensure your pup is safe from parasites and the diseases they carry. The oil’s effectiveness at treating various skin conditions in dogs is only noted in one study that we could find.

As always, your veterinarian will be your best resource when determining if neem oil is right for your dog.
