Here's why:
* They are already there: The legendary dogs, Entei, Raikou, and Suicune, are already roaming Kanto in FireRed. It's just that the game doesn't explicitly tell you where they are at any given time.
* No NPC tells you: There are no specific NPCs who will mention the dogs roaming the region.
* Finding them is part of the challenge: The game encourages you to find the dogs on your own, adding to the mystery and challenge of catching them.
How to find the legendary dogs in FireRed:
* Use the "Poké Radar": This item, found in the National Park, is your primary tool for finding the legendary dogs. It lets you locate them through a chain reaction of wild Pokémon encounters.
* Know their habitats: Entei prefers areas with lots of fire, Raikou prefers areas with electric-type Pokémon, and Suicune prefers water-heavy areas.
* Be patient: Finding the legendary dogs requires a lot of time and patience. They move around the region randomly, so you may need to search for a while before finding them.
