Camelot Pony Crupper with Block | Durable Adjustable T-Style Undertail Brown Tack Accessory with Buckles for Pony Saddle

works for donkeys too if you have a small one that you want to saddle for a child to ride to use to attach other things to a surcingle.

Even know it fit my pony it gave her rashes and broke after 1st lesson.

Took some adjusting & a few extra holes, but it works well on our 10HH pony.

I had to return my crupper strap do to it being too small for my pony. She actually fit better with a horse size.

Love the part that goes under the tail for added comfort💕
