I have seen the benefits of using both a magnetic rug and boots on a friends arthritic mare. before the afore mentioned items were used, the mare would find it difficult to get out of her stable, she was that stiff and sore. after a couple of days wearing the magnetic rug day& night the difference was there for all to see. very soon the horse that could hardly walk around its stable was being ridden out! im not saying that the horse was 100% cured, what i would say is "there was a significant improvement to her physically, to enhance her quality of life". for the reasons that I have mentioned, I believe 'magnets' are worth there weight in gold!!
