Introduction
As more Australians explore cannabis oil for personal health, pet owners are now asking the same question:
“Can I give Rick Simpson Oil (RSO) to my dog in Australia?”
With growing scientific interest in how cannabinoids may help manage pain, inflammation, seizures, and even cancer in pets, it’s understandable why dog owners are curious.
However, giving your dog RSO — a high-THC cannabis extract — comes with serious risks if not done under professional supervision.
This guide explains everything you need to know about RSO for dogs in Australia, including its potential benefits, side effects, legal status, and safer alternatives.
What Is Rick Simpson Oil (RSO)?
Rick Simpson Oil (RSO) is a full-spectrum cannabis extract made to capture all active compounds of the cannabis plant.
Unlike standard CBD oil, RSO is rich in THC (70–90%), and also contains:
- CBD (cannabidiol)
- CBN and other minor cannabinoids
- Terpenes and plant compounds
In humans, RSO is widely used for cancer support, pain relief, and inflammation.
But when it comes to dogs, this same potency becomes the reason it can be dangerous without proper medical guidance.
Can Dogs Tolerate THC?
Dogs do have an endocannabinoid system (ECS) like humans — which regulates pain, appetite, mood, and immune function.
However, there’s a crucial difference:
Dogs have more cannabinoid receptors in their brains, especially in the cerebellum and brainstem, which makes them extremely sensitive to THC.
In simple terms:
- Even tiny doses of THC can cause toxicity in dogs.
- RSO, which is very high in THC, can easily overwhelm a dog’s system.
While there are cases where micro-dosed RSO was used for canine cancer or arthritis, it must only be done under veterinary supervision.
Is It Legal to Give RSO to Dogs in Australia?
In Australia, RSO is not legally approved for veterinary use.
According to the Therapeutic Goods Administration (TGA) and the Australian Veterinary Association:
- RSO and all THC-rich products are not licensed for animal prescriptions.
- Veterinarians cannot legally prescribe cannabis or THC products for pets.
- Only CBD-based formulations (with 0% THC) are being explored for veterinary use via clinical trials or special compounding pharmacies.
Important: Giving RSO to your dog without veterinary oversight could breach animal safety laws and put your pet’s health at serious risk.
Potential Benefits of Cannabinoids for Dogs
While RSO itself isn’t approved, cannabinoids in general — particularly CBD — have shown promise for certain pet conditions.
Early studies and pet owner reports suggest that cannabinoid therapy may help with:
- Cancer symptoms such as pain, appetite loss, and inflammation
- Arthritis and mobility problems
- Chronic or neuropathic pain
- Epilepsy and seizure management
- Anxiety and aggression
- Post-surgical recovery and stress
However, most of these benefits come from CBD-dominant, non-psychoactive products, not high-THC RSO.
Risks of Giving RSO to Dogs
Because RSO is extremely potent, even a tiny mistake in dosing can cause THC toxicity.
Symptoms of overdose include:
- Disorientation or confusion
- Tremors or stiffness
- Vomiting or drooling
- Trouble walking or standing
- Loss of bladder control
- Dilated pupils and lethargy
- Seizures or coma in severe cases
If your dog shows any of these symptoms after ingesting cannabis, go to an emergency veterinarian immediately.
RSO Alternatives for Pets in Australia
Instead of using RSO, Australian pet owners should consider CBD-only or hemp-derived oils. These products contain no THC and are far safer for animals.
Safer Options Include:
- CBD oil for pets (0% THC, hemp-derived)
- Vet-approved nutraceuticals containing cannabinoids
- Compounded cannabis formulations prescribed by integrative vets
Some overseas brands, such as Canna-Pet, VetCBD, and ElleVet, are pioneering pet cannabinoid research — though importing them to Australia must comply with TGA and Customs regulations.
If You Still Choose to Try RSO (At Your Own Risk)
If, despite all warnings, you decide to try RSO for your dog, follow these strict harm-reduction steps:
- Start Extremely Small:
Begin with no more than 0.1 mg THC per kg of body weight, once per day. - Always Dilute:
Mix RSO with MCT or coconut oil to reduce concentration and make dosing more precise. - Monitor Closely:
Watch for signs of sedation, panting, anxiety, drooling, or poor coordination. - Never Use Human Products:
Avoid gummies, edibles, or capsules meant for people — many contain xylitol or chocolate, both toxic to dogs. - Consult a Vet Immediately if any adverse effects appear.
Remember: RSO is meant for humans, not animals — and a safe dose for you could be toxic for your dog.
Final Thoughts — Should You Give RSO to Your Dog in Australia?
At this time, the answer is no — not without veterinary supervision.
While some owners claim RSO helped their pets with cancer or arthritis, the scientific evidence is limited, and the risks outweigh the benefits.
Safer, CBD-based alternatives are available in Australia and are non-psychoactive, vet-friendly, and legally accessible under certain conditions.
If your dog is struggling with chronic pain, anxiety, or cancer symptoms:
- Talk to an integrative or holistic vet experienced in cannabinoid therapy.
- Ask about CBD formulations designed for pets.
- Avoid using human RSO products.
As laws continue to evolve, Australians can expect better and safer cannabinoid options for pets soon.
