A recent international study suggests that the continuous use of cannabidiol (CBD) by companion dogs may be linked to a reduction in the intensity of aggressive behaviors. The research followed over 47,000 dogs between 2019 and 2023, analyzing health data, age, lifestyle, and the use of CBD or hemp supplements.
Results show decrease in aggressiveness
Initially, many of the dogs that received CBD showed higher levels of aggressiveness than those who did not, which raised concerns. However, with regular use over time, these dogs showed a tendency to decrease in the frequency and intensity of aggressive behaviors, while dogs without use maintained more stable patterns.
The study sample included older dogs on average, about three years older than the others, and many lived with chronic conditions such as osteoarthritis, cancer, or dementia.
This raises the hypothesis that the positive impact of CBD in this context may be linked to the improvement of discomforts or chronic pains, which influence behavior.
Limits and cautions: what the authors recommend
Researchers emphasize that the findings are not conclusive. According to Marijuana Moment, they point out important gaps: there are no detailed public data on the administered dosages, the formulations used, or the exact frequency of use. Additionally, the study did not consistently evaluate effects on anxiety or agitation, distinct aspects of aggressiveness.
Therefore, the authors suggest caution: the use of CBD in dogs should be done under the supervision of a veterinarian, with special attention to the product's source and the animal's health history.
