In Pokémon Platinum, Buneary evolves at any level because it requires a lot of Happiness which means you'll just need it to have high happiness then level it up. In order for a Pokémon to have high Happiness, you can keep it in your party, never let it faint, give it Massages, give it Vitamins such as Protein and Iron and use EV-raising Berries (Tamato Berry, Kelpsy Berry, Pomeg Berry, Qualot Berry, Grepa Berry and Hondew Berry) on it.
