Is CBD safe for dogs? 

What Current Research Suggests

More families than ever are asking thoughtful questions about plant-based therapies, not just for themselves, but for the animals they love. As CBD becomes increasingly common in human wellness routines, many pet owners are wondering: Could this also support my dog’s quality of life?

What is CBD and How May it Help Dogs?

 What we do know is encouraging but rather nuanced. Like humans, dogs have an endocannabinoid system (ECS), a regulatory network involved in maintaining balance across mood, inflammation, immune function, and pain perception. Cannabidiol (CBD), a nonintoxicating compound derived from Cannabis sativa L. (commonly known as hemp), interacts with this system in ways researchers are actively working to better understand.

Below, we take a careful look at what current research suggests about CBD for dogs to include where the evidence is promising, where questions remain, and how to approach this topic thoughtfully and responsibly.

Potential Benefits of CBD for Dog 

1.Support for Aging Dogs and Behavioral Changes

A 2025 study observed survey data from the Dog Aging Project (DAP), which contained dog data from 47,444 owners. Researchers found that 2,592 dogs were reported to infrequently or frequently use CBD. The average age for frequent use was 10.2 years and most often for chronic conditions such as dementia, osteoarthritis, epilepsy, hip dysplasia, cancer, chronic diarrhea, and GI disorders. A consistent long-term use comparison, with 331 dogs using consistently for at least 2 years and 17,399 consistently not using for at least 2 years showed that those dogs using CBD long-term had significant decreases in aggression, reactions to unfamiliar circumstances, and reaction to animals. 

2. Mobility and Joint Comfort

Mobility issues are common in older dogs, and early research suggests CBD may help support joint comfort. A 2024 doubleblind, placebo-controlled study evaluated CBD with and without NSAIDs in dogs with mobility disorders to understand the cannabinoids potential role in improving comfort and movement. When compared to baseline, the dogs receiving CBD oil in the study showed a significant increase in both moderate and total activity counts. Though promising, more research is needed to determine optimal dosing and safety considerations when co-administered with NSAIDs and other medications.

3. Pain

A 2023 review highlights the safety profile and potential benefits of CBD in canine osteoarthritics (OA). For dogs undergoing treatment for OA, utilizing full-spectrum CBD oil appeared to reduce pain severity and interference scores. Few adverse events were reported, but included vomiting and asymptomatic increase in alkaline phosphatase levels. 

It is important to note that THC sensitivity in dogs differs significantly from humans, and improper dosing may lead to unwanted or adverse effects. Any THC-containing product should only be considered under direct veterinary supervision.

4. Anxiety Related Behaviors

Some owners use CBD to help dogs cope with stressors like fireworks, travel, or separation. While large-scale studies show mixed results, a 2023 published study aimed to understand the effect of single-dose, THC-free CBD distillate for dogs left alone in the car while traveling. Some results indicated significant reduction in canine stress compared to the placebo group. , although a reduction in aggressiveness and discomfort was realized. These  findings highlight the importance of individualized approaches when considering cannabis-based therapies for anxiety-related disorders among dogs.

5. Support for Dogs with Seizures

The anticonvulsant effect of CBD has been confirmed across several animal and human trials, gaining attention from the veterinary practitioner community given that idiopathic epilepsy is the most common neurological condition amongst dogs. Findings show a ≥50% reduction in epileptic seizure frequency and is recognized as safe and well-tolerated.
