National Pet CBD Day is observed on April 21 to raise awareness about the beneficial properties of cannabidiol (CBD) for pets. This day highlights how CBD, a phytocannabinoid found in cannabis plants, can improve the lives of animals, particularly in managing conditions such as epilepsy, cancer, aggression, and mobility issues. While CBD does not contain tetrahydrocannabinol (THC), the psychoactive compound in marijuana, it has been recognized for its potential health benefits for pets. Typical customs may include educational events, discussions about pet health, and promotions of CBD products aimed at improving animal well-being. The day serves as an opportunity for pet owners to learn more about the uses of CBD in veterinary care and to consider its application for their pets' health needs.
