Kind of off-topic, but... I've been in classes with TAs who were far and away better instructors than the professor, and sometimes more up-to-date on the topics .

This is sort of what I was thinking when I suggested that a new (novice) dog trainer might (reemphasize might) be OK in some ways in place of a long time trainer depending on the level and emphasis of the specific class. The novice may have assisted an outstanding trainer for years and is just now branching out on his/her own. The trainer may have years of training of his/her own animals and is now getting into training other's dogs. But being new could just as easily be a negative due to inexperience. As I said, I would think it is situational.
Years ago I was a TA for two semesters for a Purdue Univ. Business department professor teaching a course on Industrial Safety. After reading the review documents following my 1st semester, the professor (who had spent all of his training in Industrial Safety as an academic while I was in an industrial facillity) sat in on my class to pick up tips from me. My 3rd semester, I was certified to teach the class with full credentials.
