I guess this is kind of a silly question, but I'm wondering if someone could explain the meaning of a horse being "foundation bred" to me. I've heard that all breeds have horses within them that are "foundation bred" but I hear it most used with QHs and appys. I have a general idea of the meaning, but would like a deeper explanation. One specific question I have is, does the meaning change between different breeds?
So explain away, breed gurus! Thanks so much in advance!
