Abstract

 

Objective

We aimed to examine the effects of cannabidiol (CBD)-containing hemp oil without delta-9-tetrahydrocannabinol (THC) as a supplemental treatment for canine atopic dermatitis (CAD), as well as its adverse effects, and effects on concurrent drug use in dogs.

 

Animal

In this retrospective case series, 8 dogs with CAD were diagnosed by veterinary dermatologists certified by the Japanese Society of Veterinary Dermatology.

 

Procedure

The medical records of dogs supplemented with CBD-containing hemp oil were evaluated with respect to signalment, physical examination, plasma C-reactive protein concentrations, pharmacologic management, the CAD Extent and Severity Index (4th iteration), and the Pruritus Visual Analog Scale.

 

Results

Overall, CBD, used as a supplement in combination with other drugs, was well-tolerated over a wide dose range and decreased the occurrence of pruritus in dogs with CAD when ingested twice a day.

 

Conclusion

This study provides the first report of supplementation with CBD without THC that was effective in controlling pruritic behavior in dogs with CAD.
