My 7 year old dog started showing signs of arthritis; stiffness and limping, particularly after first getting up from sleep, much subdued excitement, and refusing go on long walks, but some improvement if she was limited to short walks. I started giving here 3 mg of boron a day, and 100 mg of vitamin K2. She improved after about 4 weeks, then when I quit the treatment she got worse, only to improve again when I re-started these supplements.
Not a scientific approach, I know, but as long as she is comfortable and her old frisky self, it is good enough for me.
