There is currently a lack of scientific research on the use of CBD in animals. Veterinarians may be hesitant to recommend its use. Additionally, CBD products marketed for use in animals are not regulated by the FDA, which means that the purity and dosage of the products may be inconsistent. This can make it difficult for veterinarians to determine the appropriate dosage and potential side effects of using CBD in animals. Until more research is conducted and regulations are put in place, veterinarians may be cautious about using CBD in animals.
