The idea is not a new one. It was Cesar Millan, who noticed that nearly all dogs behave really well at dog shows. He discovered with their owners after shows that the majority of their dogs are not so perfect in the street or in the park, but he kept that "dog show phenomena" in his mind for some possible training in the future. The secret is hidden in the fact that dogs vertually are unable to isolate the object of irritation in the environment of high concentration of similar objects, in other words - the reason is - there are too many dogs in one place at once. Taking in consideration that our dogs are mainly motivated by smells when it concerns other dogs ( even their olfactory system has a second function exactly for that), they are terribly confused. Confused, like your own nose is confused in a big store perfume department, many people hate to be there and that is understanding.
Cesar Millan tried to develop a technique anyway. He filled a large room with many different dogs and tried to calm down some dog-reactive individuals this way. It worked, but not for every case. So, you just have to try, but don't expect magic - only it become easier for your dog to isolate another dog, like in the wild woods, or even in the fresh morning air in the empty street - he will be back to square one, reactive as ever.
Instead, I suggest you to use a clicker training for misbehaviour. It works, clicker is a great reinforcer.
