I'm trying for a couble of days to breed a Riolu. I' ve cought a male one 56lv an a female one 55lv and i leave them at this new day care and i' ve waited for a lot of time by running up and down but nothing. I' ve tried the same thing using a Ditto but still notning. What i' m i doing wrong? Do i have to evolve them to Lucario so they can breed?
