Full spectrum CBD oil has alleviated my dog's limp from arthritis - and she has no idea what a placebo effect is, lol. We gave it to her for 2 months and noticed the improvement then stopped for one month. She started limping again near the end of the month. We put her back on the CBD and the limp was gone in a week. It's been 4 months now and zero limping. This was a condition she had for well over a year and the vet had her on a drug that made her vomit so we stopped using it (rimadyl). No side effects with the CBD....except the munchies, haha. I'd try it if I was having muscle or arthritic pain, why the heck not. Her CBD is not an ointment, though, it is a liquid on her food.
