Overview
- Dogs given CBD or hemp supplements over multiple years were reported to show reduced aggression compared with non‑users, based on surveys of 47,355 U.S. dogs from 2019 to 2023.
- No comparable association was found for related behaviors such as anxiety or agitation.
- In the sample, 7.3% of dogs had received CBD products and 5.8% were daily users, who were about three years older and more often had dementia (18.2%), osteoarthritis (12.5%), or cancer (10%).
- CBD use was more common for male dogs by roughly 9% and was higher in states with human medical‑cannabis laws.
- Veterinarians urge cautious interpretation given owner bias and missing dosage/formulation data, noting no FDA approval for dogs, potential gastrointestinal side effects, and a growing pet‑CBD market forecast at about $1.7 billion by 2030.
