Western and dressage are already so closely related it's not even funny. As for "QH's not excelling" in dressage, who cares? They aren't built for it. Does that mean it's not impressive when one can get out there and pull it off?No one.
However, 'doing' and 'excelling' are two different things. It remains a fact that the QH (and Paint) are typically not conformed to excel in dressage.
When the competition dressage ring and the SRS are full of QH's (or Paints) winning in dressage and performing The Airs...then we'll talk.
Until then, I'll enjoy seeing Lynn Palm introduce the western world to the benefits of 'dressage' as a way to improve the western horse in western disciplines.
I would also enjoy seeing Lynn Palm attempt bullfighting on her horse.
I don't believe any one breed of horse is "bigger badder better" then any other breed. They are all bred and built to serve a purpose. When one that was bred for and can excel at one discipline can cross over into another, that's something to be proud of, no matter the breed.
Oh and Rugged Painted Lark has TONS of QH blood in him and the build is the same.
