dog training advice jumping

My dog is hyper-active during agility training. What should I do to calm him down?
I have an 8 1 \ 2 months Australian Shepherd, He is very friendly to everyone and other dogs, well trained and educated at home. This usually 2 long walks and play with his friends every day. Now, being agile is 2x a week and a basic obedience course (this makes 3 times a week in Dog School). In training as soon as we entered the training camp starts to become wild, barking a lot (w \ C is unusual for him, 'Coz it' s so quiet at home) jumps on me and does not respect the "sit, stay and come" commands (commands he already knows). Always finish with a time of short-term training with him in the 'kick of his behavior. But when we are out of training camp, it is back to its "very high" attitude. I do not know what to do or what is wrong with him. Pls any advice.
First, it is impossible someone to tell for sure. Because the right tactic and approach depends on why it behaves this way. And there could be some reasons why you behave thus: – Lack of Focus –fear/over-stimulation – lots of function unit that is the appropriate response is different. Lack of concentration, see Deb Jones books and DVD's "In-Focus". Make a lot of shadow manipulation and classification of first. Exposing a distance of approach and work / control. No LeadOut. Do not ask to wait at the starting line – Upload and then GO! Fears / on stimulation, please book Leslie McDevitt "manage Unleashed". Are all Karen relaxation protocol. The work on socialization with other dogs. I also wonder whether the behavior is the same class as is the obedience with agility. Or if you train the 3 classes in one place (and if not, whether the behavior is slightly different). Fear / on the problem of stimulation, this could be a number of candidates who are pushing the button. And until you know you do not know how to build tolerance to it if he lay. I also had the video for yourself – I learned that my dog is nervous, you lose as a beginner when my marks were the delays and confusion. Training ground – Do not use toys or drawing, depending on the food (which tends to relax) during class. Do not run a cycle – 2.3 Just run obstacles, reward and an end. Do not run until it loses focus and zoom control and roll and rewarding while still under control. Use LeadOut. Referencing early and clear (a dog training school can go to the frustration and lost when signals are final). Secondly, I know I say some of the misconduct that occurs when they enter school, even before a race. Good, that combines all that is (a chance to do what you love, exposure to what you fear, something that loses focus on) with the school or on the floor. Any opportunity to receive a particular class on the basis that no one else is there? Takes Lead accommodation and only practice and reflection? Third, get Susan Garrett the DVD "Crate Games". Trying to take her to the park and only practice of crating him, control and direction. Reward for good behavior in the box open it, but should stay out and call the reward for a reward for good behavior.
