Dog Health Questions: What are some good dog-training tips?

I have taught my dog so many tricks, and I want to teach him more~ but I don't know what else to teach him. I have taught him the following:
sit, stay, lay down, roll over, stop drop and roll, jump up, sit up, kisses, shake, and hand signals for all of them. He really is a smart dog, and I want to teach him more because I hope that someday he will be a showdog. Please give me some tips! Thanks!
