I recently checked the fit on my geldings saddle and found it was too small for him. I've bought him a new saddle that fits him but his back is very tender. I know that this is from the ill-fitting saddle but am not sure what I should do about it. Somebody suggested a back massage and I have also been told that it is best to let the back rest and heal by itself.
Obviously, I have stopped riding him atm and any advice would be appreciated! Thanks
