Fortunately, if it's your Pokemon that's on the walk you are worried about you CAN retrieve it :]
To get your Pokemon back, go to the pokewalker screen and hold: Up + Select + R
If by any chance you get a new Pokewalker or find your old one, you will need to reset it, this can be done by connecting the pokewalker to the game and holding:
Down + X + L
Good luck :D
The pokewaker is where you can level up you Pokemon by just walking. You can buy Pokemon only Pokemon I know is chickoreta.]You have to send your Pokemon over to your pokewaker.
