Efficacy of Cannabidiol for the Treatment of Osteoarthritis in Dogs

Return to the Clinical Trials Homepage


This clinical trial has expired. 


Who Qualifies?

Dogs with arthritis affecting one or more joints. Dogs must have a visible lameness that has been present for at least 4 weeks. Upon enrollment, every dog will be evaluated by an orthopedic surgeon and any medication adjustments will be made prior to starting the trial.

Purpose of the Study

The aim of this study is to assess the efficacy of a component of the Cannabis sativa plant, cannabidiol (CBD), in treating canine osteoarthritis. The CBD product is very low in the psychoactive component of cannabis, THC, making it safe for use in dogs. Each dog will be randomly assigned to receive either a placebo or CBD oil for 6 weeks and then "crossed over" to receive the opposite medication for the subsequent 6 weeks.

What is Required?

  • Radiographs (x-rays) to document the arthritis
  • Daily pain assessment questionnaires to be filled out by a single owner
  • 15 minutes of walking per day
  • An activity tracking device hooked up to home internet
  • Reassessment and bloodwork weekly for 4-6 weeks and then every 6 weeks thereafter


All costs related to the study will be covered in full, including the examinations, radiographs, gait analysis, joint measurements, bloodwork and the CBD oil.
