A systematic review of 22 studies found CBD-based products improved pain, seizure control, and behavior in dogs, with no serious side effects, though research in cats is minimal.
Veterinarians, pet owners considering CBD products, veterinary researchers
22 studies show CBD benefits for pets with no serious adverse events
What the researchers found
Across 22 studies, CBD-based formulations showed benefits for osteoarthritis pain, epilepsy, atopic dermatitis, postsurgical pain, and behavioral issues in dogs, with no serious adverse events reported. Research on cats was limited to just two studies.
Why it matters
Pet owners are increasingly using cannabis products for their animals, often without veterinary guidance. This systematic review provides the most comprehensive evidence assessment to date for clinical decision-making.
The numbers in context
22 studies identified. Conditions: osteoarthritis, epilepsy, atopic dermatitis, postsurgical pain, behavioral issues. Only 2 cat studies. No serious adverse events. Long-term data limited.
How the study worked
Systematic review of PubMed, LILACS, Scopus, and Google Scholar from 2014 to 2024, identifying 22 studies on cannabidiol-based products in dogs and cats.
What this study cannot tell us
Most studies are small and vary in design quality. CBD product formulations differ across studies. Very limited cat data. Long-term effects unknown. Optimal dosing not established.
How to read the evidence
Systematic review methodology applied, but underlying studies vary in quality and most are small.
When this study was published
2025 systematic review covering veterinary CBD literature from 2014-2024.
The bigger picture
The veterinary CBD market is growing rapidly, often outpacing the evidence. While early results are encouraging, the lack of standardized dosing and long-term safety data means veterinarians are largely operating without clear guidelines.
Questions still open
- What are the optimal CBD doses for specific pet conditions? Are there breed-specific differences in response? How does CBD interact with other veterinary medications?
Common questions
Is CBD safe for dogs?
Does CBD work for cats?
