How interesting! Its amazing the history and experience that can be revealed by steemit members. They're a lovely breed. Intelligent, strong for their size, robust and heaps of character.
They apparently can have have fewer ribs than other breeds (depending on cross breeding) to allow their lungs to expand more so that they can work harder with more air. They're well suited to heat and cold. Just a gorgeous and capable breed. Very intimate when trrated well and very firey when not.
They have a bad reputation among the barn-which community because they tend to resist all the bad handling techniques that are so common with most horse owners. I find it's never the horses fault!
I'll have to check out your post later today. Thanks!
