I am looking for a cart and harness for my miniature horse and the sellers are talking about A and B miniature horses that will fit the carts. But I don't know what an A and B miniature size is...I feel kinda stupid but I honestly don't know! Can someone explain to me what is the difference between an A miniature and a B miniature? Thanks!!
Also, if you know where I can get a cheap harness and cart at for my miniature (36 inch miniature) that would be awesome!! Thanks!
