Dogs who receive daily doses of CBD see “significant reductions” in stress and anxiety related to car travel, according to a new study.
To investigate the issue, researchers at the Waltham Petcare Science Institute in the United Kingdom compared the behavioral and physiological stress response of dogs who received THC-free cannabis with a placebo group before, during and after drives.
The 20 dogs involved in the study, published in the Journal of Animal Science, all exhibited signs of stress and anxiety when riding in a car—but the canines treated with CBD two hours before taking the trip showed meaningful improvements over a 24-week review period.
Certain measures of stress such as whining and levels of the hormone cortisol in the blood “were significantly influenced by CBD administration,” the study says, “indicating daily dosing at 4mg/kg may have a mild anxiolytic effect on dogs when traveling in a car.”
The placebo group’s stress levels also decreased by the end of the study, suggesting that the dogs became habituated to driving. But the CBD cohort on average had lower post-test cortisol from the onset of the treatment that were sustained.
“Daily dosing of cannabidiol (CBD) demonstrates a positive effect on measures of stress in dogs during repeated exposure to car travel.”
Because cortisol was still present in the blood, the authors said the non-intoxicating cannabinoid didn’t seem to completely eliminate stress, so they posited that CBD is…
