You will need to find a small pony saddle. Then you will have to just try it on to see if it fits. Its hard with the smaller minis to fit a saddle. With our minis under 34in the kids just normally ride bare back while we lead them. We do have a saddle that fits our 36 inch minis and the kids. Sometimes the problem with finding a saddle that will fit the mini is that then it will not fit the child or vise versa. But try on a number of pony or mini saddles. You can also pull up mini tack online and there should be a bunch of websites that sell mini tack and will have saddles and bridles both english and western. Good Luck.
