* Entei: Entei can be found in the burning tower in Ecruteak City. This tower is accessed by going through the back of the town and past the Gym. The tower is burning, but you can battle Entei inside.
* Raikou: After capturing Entei, Raikou will roam the Kanto region. You can use the Radio Tower in Goldenrod City to track its location. The radio will announce where it is located on a certain channel. You'll need to chase it around.
* Suicune: After capturing Raikou, Suicune will roam the Kanto region. You can use the Radio Tower in Goldenrod City to track its location. The radio will announce where it is located on a certain channel. You'll need to chase it around.
Important Notes:
* They are at a high level: The Legendary Dogs are very powerful, so you'll want to be sure you're well-equipped and have a strong team before encountering them.
* They are fast: They can easily escape, so make sure you have Poké Balls ready and a good plan to catch them.
* They are not in the same location: After capturing one, the other two will wander randomly, so you'll need to use the radio to track them down.
* One at a time: You can only catch one Legendary Dog at a time. You'll need to find them again to capture the others.
Good luck catching them!
