Why
Dogs are more sensitive to THC than humans. Ingestion of cannabis flower, edibles, concentrates or vaping products can cause marked sedation, wobbliness, dilated pupils, low body temperature, vomiting and urinary incontinence. High doses or products with chocolate or xylitol are especially dangerous. CBD products without THC are less toxic but can still cause side effects.
