How can I teach my dog new/more tricks?

[Owner]

Well outside of heeling and speaking on command (working on that) I have taught my dog a fair number of tricks. He sits, lays, jumps, dances and rolls over (the full 360 roll).

I wanna know what other tricks I can teach him. He is a toy australian shepard, and they are quite small, but extremely smart. I understand using treats is the way to get him to do what you want, but I would like to know if there are any other ways.

Also any other tricks would be nice. Nothing like a double back-flip, but if anybody else has any more tricks, and way to do that I would love to know.

Yea...no Pet-co dog training...he is too hyper as it is...and extremely shy around other dogs...

Btw he will be 2 in August
Nobody liked to be punched...especially a 11 lb dog
