With the growing popularity of CBD in human wellness, many pet owners in the UK are exploring its use for their animals. From calming anxiety to supporting joint health, anecdotal reports suggest that CBD may help pets live more comfortable lives. But before you reach for that CBD oil for your dog or cat, it’s important to understand the legal framework and veterinary guidance surrounding its use in animals.

What Is CBD and Why Are People Using It for Pets?
CBD (cannabidiol) is one of many active compounds found in the cannabis plant. Unlike THC, CBD is non-psychoactive and is widely believed to have calming, anti-inflammatory, and pain-relieving properties. Pet owners around the world have begun using CBD to address conditions such as:
- Separation anxiety and stress
- Arthritis and joint stiffness
- Seizures and neurological disorders
- Skin irritations or allergies
However, most of the evidence for these benefits is anecdotal or based on early-stage research. There is limited clinical data on how CBD affects animals, which contributes to the cautious legal stance taken by regulators.
The Legal Status of CBD for Pets in the UK
In the United Kingdom, the Veterinary Medicines Directorate (VMD) oversees the regulation of animal medicines. According to the VMD, CBD is considered a veterinary medicine when used to treat or support animals.
Under UK law:
- Any CBD product marketed for pets must be authorised by the VMD.
- Currently, there are no CBD products authorised for animal use in the UK.
- Companies cannot legally advertise or sell CBD products as suitable for pets.
This means that if you see CBD products labeled “for pets” in the UK, they are not compliant with current regulations—even if they are widely available online.
Can a Vet Prescribe CBD for Your Pet?
Yes, but with limitations.
While pet-specific CBD products are not legal for sale, veterinarians are allowed to prescribe human CBD products for off-label use in animals under what is known as the “Cascade” system. This allows a vet to prescribe a medicine not licensed for that species if no suitable veterinary alternative exists.
In practice, this means your vet could recommend a human-grade CBD oil for your pet, especially in cases where conventional treatments have not worked or are unsuitable. However, this must be done with careful consideration and appropriate dosage adjustments.
Safety Concerns: Why THC-Free Matters
One of the most important safety considerations when using CBD for pets is ensuring the product contains no THC. THC, the psychoactive compound in cannabis, can cause serious health issues in pets, including:
- Lethargy or hyperactivity
- Tremors or seizures
- Vomiting
- Loss of coordination
- In severe cases, toxicity requiring emergency veterinary care
For this reason, vets typically recommend broad-spectrum CBD or CBD isolate products—both of which contain zero THC.
What Pet Owners Should Do
If you’re thinking about trying CBD for your pet in the UK, here’s what you need to know:
- Speak to Your Vet First
Never start a CBD regimen for your pet without professional advice. A vet can help assess whether it’s appropriate and suggest a safe, effective product and dosage. - Only Use Human-Grade Products
Since pet-labeled CBD is not legal in the UK, stick with high-quality human CBD products recommended by your vet. - Check for Lab Reports
Only purchase CBD from reputable brands that provide third-party lab testing to confirm the absence of THC and the presence of CBD at stated levels. - Monitor Your Pet Closely
Start with a very low dose and observe your pet for any signs of improvement or side effects. Adjust only under veterinary supervision.
