I've never used them myself and have remained extremely cynical about the claims made by the vendors.
However, when we used to race greyhounds some of the trainers swore by the magnetic bands that were available to help the dogs over wrist/hock injuries. Obviously the dogs wouldn't comment on the effectiveness of these devices - but the results seemed to bear out the claims.
I'm glad it works for you MP, there's obviously something in it for people as well as mutts.
