If your Eevee is female, simply leave it in the care of the Daycare Couple on Route 34 with another Pokemon in the Ground Egg Group that is male (or a ditto if your Eevee is male). It is here they will breed.
Run or ride your bike close by until the Old Man calls you and hands you an egg. Take your Pokemon out of the daycare (or leave them if you want more eggs), and continue to run/ride around. Eventually your egg(s) will hatch into level 1 Eevee.
To evolve the Pokémon Eevee in Pokémon HeartGold and SoulSilver, you can choose either of the two choices described below:Train Eevee in the nighttime when it has max happiness.Train Eevee in the nighttime when it is around a Moon Shard.Steps have nothing to do with the evolution of Eevee.
you cant.
Bill gives one to you sometimes
Yes u can
u can't u have to level up eevee near snowpoint city in diamond/pearl/platinum and trade into soulsilver and heartgold
Pikachu to Riachu, and Eevee to Jolteon.
Breed in the daycare with ditto
I have heard from sources that you can get an eevee from Bill and you evolve eevee into espeon by making it like you a lot and evolving it in the morning. Otherwise, you can't.
you cant get glaceon or lefeon in soulsilver
Up your friendship with Eevee, then level it up during the day.
Once you get an eevee from Bill. (House in Goldenrod City gives one for free) take it and a ditto to day care. Leave them in there. Soon there will be an egg there. Hatch it to an eevee.
In Pokemon soulsilver, after you encounter with bill the first time you can go to goldenrod city and go to bills house and he will give you an eevee. if you want to breed eevees then you should make sure you save before talking to bill when he gives you the eevee. the best way to breed an eevee in soulsilver is to put a ditto and a female eevee in the daycare. and to get a jolteon you need to have the thunderstone. give the thunderstone to an eevee and it will evolve. you can get the thunder stone from the pokelthon dome.
