How do you catch all 3 legendary dogs in Pokemon crystal? - Answers

They are the legendary cats, not dogs. The Pokemon Company revealed that Raikou is a tiger, Entei is a lion, and Suicune is a cheetah. You get Suicune by getting about 7 or 8 gym badges. To capture it, you need to go back to the Tin Tower, where the old guy was guarding the tower, He'll let you through, and you go into the tower after a short walk. Go up the tower a bit, and Suicune's there. You battle it. The only way to get the other two is by searching in random places. They appear as wild Pokemon, and flee on the first turn, then run to some other different location. Their location is completely random each time you enter a new Route or Town, so all you need is luck and skill.
