If you do put a brace in then you can't show because you have alterd the natural conformation of your dog (and if people have done this I very much they would doubt would say in public!!!)
All you can do is hope that the teeth go back, unfortantly, at this age, unlikly!
Edit: Just relised to say Canines infrount of upper teeth? What do you mean??? Lower Canines are ment to be infrount of upper canines, if the lower canines are infrount of upper inscisors that I don't think even a brace could sort that out!
