Saddle pads for a swayback horse.

I recently purchased a horse who is a 22 year old Saddlebred. Now I purchased a saddle from the lady that sold her to me and she also gave me a special smaller pad that goes on along with a regular saddle pad. The small pad seems to make the saddle I have fall off of my horse. So I am trying to figure out what saddle pad is good for swayback so I only need to use one saddle pad and not two.Thank you for reading

Hey and welcome to the Forum! I love Valley Vet Supply catalog. I've bought saddle pads from them and I have always been very pleased. They sell swayback pads and I'm pretty sure you can find something to fit your needs. I also like Jeffers.... Good luck!

Welcome to the Forum, Melanie!

Could you post some pics of the horse may be (with no saddle on)? And what kind of riding you do?
