There are several exams and several training technics......we were talking about IPO because Daiva wrote about it.
My personal oppinion is yes Margo...csw's are very intelligent, could study easily.....but not the classical working dogs , and not the breed which is good for IPO work. It is not means that some of them couldn't pass.....but those who worked with malinois or gsd...those surely could feel the differences
