Can you catch the three legendary dogs in rubyred?
In Ruby, Sapphire, or Emerald, the only way to get the legendary
dogs is to trade them from a previous game.
In Fire Red, and Leaf Green, you can only obtain one dog. The
other two you have to trade over. Which ever dog you can get
depends on your starter. If you started with Bulbasaur you can
catch Entei. If you started with Charmander you can catch Suicune.
If you started with Squirtle you can catch Raikou. The dog is
roaming around Kanto.
