If you are looking for a really fun dog sport we would strongly recommend that you take a look at the Mondioring sport. It's far more interesting than Schutzhund, both for the dog and the handler. A point I would like to mention here is you can see that this 16 month old dog has a very nice finished retrieve. Rush has been trained to retrieve with markers and without corrections. Because of this he approaches the work with a great attitude and confidence. He is not worried about what you are going to do to him if he makes a mistake.
Michael and I will do a motivational retrieve training DVD later this year.
