My old barn had a mini named Doc.. SO cute, but he was a nasty little bugger! My friend's 16.3hh Warmblood got in a fight with him over their common fence and he (the big horse) ended up with part of his neck torn off! He would escape from his paddock every once in a while and loved hanging out with the resident stallion, Duke. He was exceedingly nice to people! We hooked him up to a sled to do feedings in the winter... and go for sled rides!
Anyways, we just stood beside him and bent down (really far!) to pick up his feet... the farrier would kneel beside him to trim him up though... :)
Haha it's not too hard, you figure it out pretty quick. And on the up side, if he refuses to give you his foot, it doesn't take much to "convince" him to! :P
I've always wanted a mini!! Now that I've found a cheap/free place to board, I might just adopt one...
Doc is adorable, but a cheeky little bugger... and faaaat! Holy crow! You really have to watch their weight, they'll eat and eat....!!
