New data from the large-scale Dog Aging Project suggests that long-term cannabidiol (CBD) use may be associated with reduced aggression in some dogs, although the picture is far from simple. Researchers analysed reports from more than 47,000 dog owners, finding that just over 5% of dogs were given CBD, most often for conditions such as dementia and osteoarthritis rather than behaviour alone.​

Dogs receiving CBD initially showed higher-than-average aggression compared with non-CBD users, but over time their aggression scores dropped below those of dogs not given CBD, hinting at a possible calming effect or relief of underlying pain and inflammation. The authors stress that factors like training and other medications could also explain the change and call for controlled clinical trials before firm conclusions are drawn.
