I have used pet CBD for my pets for severe joint and arthritic pain. My dog who died recently, would not have walked well the last 2 years of his life without it. Basically, there is very little clinical research in this area, but CBD in humans has no harmful effect and in pets anecdotally, it seems to across the board, help pets. I am a big fan of Treatibles as Desmond would have had to be on pharma drugs that made him a dog zombie and on Treatibles he seemed happy and in far less pain. I hope this helps you!
