Castor oil is a natural substance that was used as far back as 4000 BC for medicinal purposes. It is an old remedy for constipation in dogs. Although it’s okay to use under explicit directions from your vet, we don’t recommend castor oil as a first-line treatment for any ailments.
The risks of giving castor oil without veterinary advice outweigh the benefits in most cases. Read on to learn more about the historic use of castor oil, the risky side effects, and safer alternatives for your dog.
What is Castor Oil?
Castor oil is made by cold-pressing castor beans from the castor oil plant (Ricinus communis). Castor beans in their natural form are highly toxic to dogs due to the ricin content, which causes illness within 12–48 hours of ingestion.1
Castor oil doesn’t contain ricin since it is removed and deactivated during processing. It is composed mainly of ricinoleic acid, which is responsible for its efficacy as a cathartic agent. Only food-grade castor oil produced by reliable manufacturers should be used medicinally. It should be stored in a cool, dry place and used before the expiration date.
Castor oil is an outdated remedy for constipation in dogs, but it has been shown to stimulate peristalsis of the colon, leading to defecation.2 Think of peristalsis as a stadium wave of colon muscle contraction; the contraction moves along the colon to guide feces toward the exit.
Due to the bitter taste and side effects, castor oil has fallen out of favor in veterinary medicine, with preference being given to other, less noxious laxatives. There is little evidence for other uses of castor oil in dogs or people.
Despite that, it is sometimes used as a topical remedy for minor skin wounds or irritations. In people, it may be used as an alternative treatment for arthritis, headaches, menstrual cramps, labor induction, or dry eye; however, these uses aren’t supported in dogs.
How Is Castor Oil Given?
Castor oil is a liquid that can be drawn up with a medication syringe. With veterinarian approval, you can give castor oil orally. The best way to do this is to mix the castor oil with wet food.
The dose and frequency can be adjusted to produce the desired effects in your dog, but we recommend starting with small doses, especially in smaller dogs. Your veterinarian can advise you how much castor oil is appropriate for your dog, but a general guide can also be found here.
For topical use, you can make a castor oil pack to place on your dog.3 We don’t recommend using external heat on the castor oil pack, as your dog won’t be able to tell you if they are getting burnt by it. You should also start with just a drop of castor oil on the skin and monitor for allergic reactions before using a castor oil pack.
What Happens if You Miss a Dose?
If you miss a dose of castor oil, your dog will not be harmed, besides the reduced laxative effects. You should only use castor oil under the instructions of your veterinarian. If you miss a dose, contact your veterinarian for advice regarding the next dose.

Potential Side Effects of Castor Oil
Castor oil has a horrible taste and aftertaste. For this reason, it can be hard to administer to animals. When it’s syringed directly into dogs’ mouths, there is a risk that they may inhale the oil, leading to aspiration pneumonia, which can be severe and life-threatening.
Castor oil ingestion can cause vomiting and diarrhea, especially in larger doses. Vomiting and diarrhea can lead to dehydration and electrolyte imbalances, which can make dogs very sick. In cases of gastrointestinal obstructions, perforations, and inflammatory bowel disease, using castor oil may make things worse for your dog.
Humans using oral castor oil report abdominal pain and dizziness. Castor oil is thought to stimulate uterine contractions, so it’s not safe during pregnancy. It is unknown if castor oil enters breast milk when it’s used during lactation, so it’s not recommended during breastfeeding.
To ensure the safety of your canine companion, it is important to adhere to these human recommendations when it comes to their care.
It is not advisable to use castor oil on dogs, as they may lick it off their skin and experience side effects similar to those seen when ingested. The risk of side effects increases with the amount consumed. Additionally, there have been reports of allergic reactions in both sensitive people and dogs when exposed to castor oil.
If your dog is experiencing constipation, it is best to consult with a veterinarian for proper diagnosis and treatment. In some cases, natural fiber sources such as boiled pumpkin and psyllium husk can help alleviate constipation. Over-the-counter laxatives may also be used under the guidance of a veterinarian.
When it comes to skin health, omega-3 fatty acids found in fish oils have anti-inflammatory properties that can benefit your dog’s skin. For dogs with dandruff, supplementing with omega-6 fatty acids from sources like corn and evening primrose oil may be beneficial.
Overall, while castor oil is primarily used as a laxative, it can have serious side effects if not used correctly. It is recommended to only use castor oil under the supervision of a veterinarian, as there are safer alternatives available.
