Understanding the Impact of CBD on Stress in Dogs

This article discusses a scientific study conducted by researchers at the Waltham Petcare Science Institute in the UK. The study focused on the effects of cannabidiol (CBD) on stress in dogs, specifically during separation from caregivers and car travel.

What's the Study About?

The researchers aimed to understand how separation and car travel impact canine stress and to evaluate the effect of a single dose of CBD on these stress measures. The study involved 40 healthy adult dogs of various breeds and was conducted over six months.

Main Findings

  • Separation and car travel can induce stress in dogs.
  • CBD administration might have a positive effect on stress measures.


The study was a blinded, parallel design study. Dogs were randomly assigned to two groups: a placebo control group and a treatment group. The dogs were further divided into two groups to experience either a separation event or car travel.

The researchers used various tools and methods to collect data, including:

  • Wearable monitors to collect heart rate and activity data.
  • Video cameras to record dog behavior.
  • Blood samples to measure cortisol, immunoglobulin A, and glucose levels.

The dogs received a targeted oral dose of CBD (4 mg/kg bodyweight) or a placebo. The researchers then exposed the dogs to either a separation event or car travel, and collected data before, during, and after these events.

Potential Implications

The study suggests that CBD could potentially help manage stress in dogs, particularly during separation and car travel. This could improve the welfare of dogs and strengthen the human-animal bond.


While the study provides valuable insights, it's important to note that the sample size was relatively small and the study was conducted under controlled conditions. Further research is needed to confirm these findings in larger, more diverse populations of dogs and in different settings.


This study contributes to our understanding of how CBD might help manage stress in dogs. However, more research is needed to fully understand the potential benefits and risks of CBD use in dogs.
