He's a shetland I used to ride for a friend back in 2008.
I think he was 9 at the time, he was rescued & hadnt been ridden for years, until I came along & taught him to jump. He was a little monster though. Bolted with me several times, once bucked me off whilst riding bareback & took himself back to his field lol I think he was around 9hh.
As you can see, he was an impressive little jumper..those tiny barrels were only about 1ft high lol
