Been There, Doing That: Advice from Pro Dog Trainers
I think its really important for dog trainers to get a lot of experience being a student before becoming a teacher. Take as many classes as you can, in numerous disciplines, with your own dog. Youll learn how different classes are structured and what you like and dont like about them. When not actively working with your own dog, observe the other students and see how the instructor works with a variety of dogs and people.
