My friends and I have a problem with our saddles rolling over to the side when we get on. My horse in particular has a flat broad back with wide withers. Any suggestions? I know we are cinching our western saddles up tight enough.
A round, mutton-withered horse is difficult to keep a saddle on, but there are a few things that may help.
First, make sure your saddle fits. That seem like a no-brainer, but if your tree is too wide or too narrow, it’ll be more likely to slip. Often a flexible tree will hold better on a round horse than a rigid tree saddle because it shapes to the horse’s back. This is one reason I like the Circle Y Flex2 saddles.
Secondly, the saddle pad you use can really help or really hurt. Make sure you are not using too thick a pad—usually round horses don’t need a lot of padding. For the really round horses I like to use a split-withered pad—sometimes called a cut-back pad (incidentally, this also works for very high-withered horses). It helps to hold the pad in place around the withers. I also often use an open-cell foam pad that has a suction-like effect and holds on the back really well.
Make sure when you saddle that you pull the pad well up into the gullet of the saddle—causing a V-shape to the pad, which is less likely to slip. If you don’t pull it up and create an air space over your horse’s spine, the pad sits right on the withers and has a round shape which slips much easier (not to mention puts uncomfortable pressure on his spine).
Unfortunately for the round horse, you have to keep the cinch much tighter than you would on a horse with good withers. Make sure you tighten the cinch slowly—don’t gut-wrench him right off that bat—that will create a cinchy horse, or one that is resentful of the cinch. Tighten the cinch gradually over 10 minutes or so and walk him a little between tightenings. Check your cinch again about 15 minutes into your ride or before you do any loping.
Finally, you might consider using a breast collar and/or a crupper, which attaches to the back of the saddle and goes under the horse’s tail. Neither one will stop your saddle from sliding but they will help stabilize it. Good luck and be sure to keep you weight in the middle of your horse!
