"Tammy Silverman turned to CBD oil, which is derived from cannabis, to help her dog Annie with pain. 'We found out that our dog had hip dysplasia and arthritis after we did an x-ray of her,' she says. 'I took her for a walk, her legs dragged so bad, it scraped her nails and her nails were bleeding.' A specialist recommended CBD oil. Tammy thought it was a good alternative to Annie getting surgery."
