Our training facility is encouraging all agility students to read the book, In Focus by Deborah Jones and Judy Keller. I just started reading it, and I think it's going to strengthen Tanner's focus skills. The book is not about training obstacles, or handling. It's more about developing a strong working foundation. I think it would be a good book for agility handlers at any level. It's an easy read, and only 100 pages long. You can find it on clean run's website.

I'm guessing that if it deals with focus, it may help with obedience, too? I can't do agility right now because our girlie is still sore and recovering from her bilateral elbow surgery (Feb), but we're working on obedience as hard as we can!! ;)
