Is the same the foundation quarter horse and bulldog quarter horse?
I used to own a mare that was foundation bred- she descended from the Poco Bueno line and was a registered Appendix QH. But I've never heard the term "bulldog" used in reference to a horse of that breeding. And I've been a professional for decades, too.
I've been an equine professional for over 40 years and have never heard of the term "bulldog" quarter horse. Sounds like someone is using this term as slang to describe the foundation QH as the foundation strain is very stocky, heavy, slightly shorter and much less refined than the current average QH. The average QH that is not foundation is lighter, a bit taller and has slightly hotter breeding. Then you have the Appendix QH which has a lot of Thoroughbred breeding-quite tall, finer boned and sometime a much hotter horse. Really good for real hunter/jumper events-not the fake HUS you see at the QH shows. As for all these garbage "answers" with a bunch of random letters, hover over the avatar and block them and then flag them a report them to Yahoo.
