I seem to remember that there might be a Hackney horse breed and then a Hackney pony breed from reading one of those breed books. Not positive though.

Does anyone have experience with Arabian/Hackney crosses? I thought Hackneys were small, but this mare is BIG, much bigger than her dam. What does the hackney add to the mix?
