Mini Horses
Herd Master
http://www.miniaturehorsetalk.com/
Many, many, many years ago some old breeders (before registries, etc) used dwarves in breeding, thinking it would just give small horses. Sadly, many more issues were there and many carried the genetics. There are distinct types and until a few years ago there was no testing to detect the genes. Years of research, with samples from thousand of minis, dedicated workers and they now have testing available. While the genetics can be passed by one to another, it takes both parents carrying the genetics to produce a dwarf. The link above have a good deal of discussion and research info as we, as a group, were active in assisting to promote this work. The lead research was from one of the largest and best known mini farms in the country.
