Hi. I have the same problem with a new horse I just bought. He's 13 and has a little dip in the back along with high withers. I just bought a new high dollar endurance saddle this time last year so I won't be able to buy another one. Don't want to. This saddle is the BEST. It's a Boz. I bought it to use on my arab mare who I had to sell this year. Anyway, I need a pad that'll help me too. I'd like some suggestions. Can't go too high on price but I will if it'll work. I'm trying to stay away from buying pad after pad after pad before finding the one that works. Thanks. Deb
