I do not use this with my dog for calming I use it for anti inflammatory properties and soreness. I have a 90 pound mix dog who ruptured but knee tendons; I had been down the surgery route with a different dog and didn’t want to go through that again. I have been able to give a very low dose every day to Oliver and after time and healing he is up to 2 mile hikes on the weekends and I believe the CBD helps keep the inflammation down so he can be active aging and his pain is gone. If I note either of my dogs with soreness in their legs I give them a small amount and it really seems to help with pain and swelling. I also get my shipments quickly and no problems with breakage or quality of product plus the price is right.
