A very nervous street dog decided to move in with me a year ago. For a few month I gave her a couple of drops CBD weed oil in her food. It did help a little, I think. She slept more. I don't give that anymore after finished the bottle. She is much more calm now. It could be because CBD got her to relax and bring the stress level down or it could be that it because she has adjusted to her new environment. Worth a try. It wont harm
