Pet dogs often experience stress during routine car travel which can negatively affect both dogs and humans. A range of management and treatment options exist to address this, such as behavior modification, drug therapy, and supplements, yielding mixed results. Dog owners often seek strategies that are easy to administer and are effective in improving their pet’s well-being. The objective of this study was to investigate the effect daily dosing of cannabidiol (CBD) over a 6-mo period, had on measures of stress in dogs. In a parallel design study, dogs experienced short car journeys (test) and a range of physiological and behavioral measures were collected pre, during, and post-test. Significant changes in several stress-related measures including serum cortisol, heart rate, heart rate variability, whining, lip licking, yawning, and qualitative behavioral ratings were observed from baseline to test, indicating that car travel was stressful in this population. The impact of CBD treatment varied across these measures, with certain indicators showing a marked reduction in canine stress when compared to a placebo group. Additional research is required to fully understand the complex effect CBD has on the emotional well-being of dogs.
