I enjoyed the fact that you try to limit classroom and try to do as much hands on as possible. It is much easier to apply what you are saying on the training field with dogs then in a classroom. The material was prevented in an understandable way. Any questions asked were explained and applied to the K9. The ability to work on different problems was nice to see for future reference. The course was not set to a specific way and was flexible. Class size was appropriate to get the most out of class. Overall course was very helpful in understanding the Ecollar.
