First, I should note that they are not Dogs, Cats, or any other specific animal. They are the three Legendary Beast Pokemon; Raikou's design comes from the Raijū, Entei's from the Chinese guardian lions, and Suicune's from the Qilin, with a slight inspiration from Fūjin.
In Pokemon Fire Red and Leaf Green, to get one of the three Beasts - Raikou, Entei, or Suicune - you must first beat the Elite Four. Once the credits have rolled, speak to Professor Oak, who will give you the National Dex if you have registered at least 60 Pokémon in your Pokédex. Once you obtain the National Dex, one of the three Legendary Beasts will wander the grass of Kanto, depending on the starter you chose; Entei if you picked Bulbasaur, Suicune if you picked Charmander, and Raikou if you picked Squirtle. The other two Beasts you will need to trade for.
Regardless of which Beast you encounter, it will be at Level 50, and will flee from battle at the first chance it gets; saving your Master Ball for this encounter is a good idea. After the first encounter, you will be able to track its location with the PokéDex, but it moves quickly, and is incredibly unlikely to be in the same place it was when you last saved the game as it will be when you turn the game back on. Any damage or status conditions that you inflict upon it will stay in effect, regardless of how many times you meet and it flees. And, of course, it will disappear forever if you K.O. it, so burning or poisoning it is NOT recommended.
The best strategy to find it is to wander the grass of Kanto with a Pokémon of a higher Level than that of the local Pokémon (but no higher than 50) at the front of your party, with lots of Repels on hand and one in effect at all times. Encountering it the first time is tricky; it can be in any patch of grass anywhere in Kanto (not in the Sevii Islands), but this strategy is likely to make things much easier.
And one final note of importance, on a glitch in Fire Red and Leaf Green: if the Beast uses Roar to end the battle, it will vanish, impossible to be encountered again on that file. So, if that happens, it will be necessary to reset the game without saving if you wish to find it again. Therefore, if you decide to use Spider Web, Mean Look, Block, or the Shadow Tag Ability, it is recommended to put the beast to sleep first. On a side note, Suicune is the only one of the Beasts that does not know Roar.
It depends on the game and the Pokemon. After you release the Pokemon from Tin Tower they roam around the entire region and you will encounter them only by chance in Pokemon Crystal, Suicune is the only one that is captured as a part of the main storyline. The other two you will just have to do a ton of walking to encounter them and even then expect to use a ton of poke balls on them to capture them and keep them in battle with a trapping move or they will run and there is nothing you can do about it.
First, get rid of the sudowodo.
Then, go right and talk to the chubby guy. He will then give you the TM rocksmash.
Teach this to a Pokemon of you're choice (preferably one that will be with you a long time but not the starter Pokemon).
Then go to Ecruteak town and save your progress at the Pokemon center.
Next, go to the first tower up to the north west side of the screen or burnt tower if you prefer. There you will battle your rival.
Whether you win or lose go left and then north until you reach a cracked rock - you will click it and it will say something that you must click yes or no. If you click yes then the Pokemon will shatter the rock.
Next, proceed forward where you will battle another trainer. One quick hint:
WIN ok WIN
Then go down, and there will be an item after you go past a J-shaped corner. Take the item if you want. Otherwise, go down the small black hole where you will see three Little Pokemon sprites. They will run away.
You then leave. Go on with you're journey. If you see them on your way LET THEM GO. YOU MIGHT BEAT AND then, you CANT GET THEM AGAIN AFTER THAT.
You should get all your badges. After getting them. that elm will call you and ask you to swing by. You do that by flying and he will give you the ONLY possible master ball.
Give the ball to your starter then go back to Ecruteak city.
Next, go to the Pokemon center where you then deposit your beloved starter. Then, click the button that says change box. When it says saving don't turn off the power as fast as you can. Turn it off then back on and it will clone you-re started coll. Then, repeat this 5xs and withdraw them and tack their item.
You should have 6 master balls now. You go back to the tower and
1: you can go right until you get into grass patch
2. then catch the dog if he appears
3 then go left after returning to the tower
4 then catch the dog if he appears
5. and then the same thing from the tower
You WILL HAVE MORE THANN ONE MASTER BALL SO USE IT IF you have ONE LEFT.
However, I recommend you DON'T USE IT. Instead, just RUN or you can do most of the same stuff as option one or go to routes 35, 36, 37, 38,and 39 this is where they will most likely pop up USE Your MASTER BALLS.
If you mean entei, suicune, and raiku, then once you beat the elite four, one of them will randomly appear. You could be anywhere from pallet town, to fuschia city. They will appear randomly in a patch of grass. By the way, 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.
First of all you can only get 1 of the dogs it depends on what starter Pokemon you chose if you chose bulbusaur you can get entei, if you chose charmander you can get suicune and if you chose squirtle you can get raikou. Once you get the national dex and give the ruby and sapphire to celio you can find the dogs roaming around kanto the easiest place to find them is Route 1 its highly suggested to use the masterball to catch it but you don't have to do that.
You cannot catch the legendary dogs in Diamond or Pearl, you must migrate from Pokemon LeafGreen, FireRed, Colosseum, or XD.
In many ways, no. Fire has a national pokedex, alternate areas, and the chance of finding the legendary dogs!
moltres
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!
yes but it depends on who and what you are fighting
No
you dont find the legendary dogs in fire red. instead you get the legendary birds. they are zapados moltres and articuno
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
migrate from firered and leafgreen
no you cant and how would that even work.
gatch them with a master ball but trade the master balls
You need to migrate each from either firered or leafgreen or you can trade with heartgold and soulsilver after they got them.
it depends on which starter u chose. squirtle: raikou. bulbasaur: entei. charmander: suicune.
You can only catch one of the dogs which depends on what starter you chose to get the rest get one from firered to get the second and the third from Pokemon colosseum.
You can only get 1 which is decided by what starter you chose. To get the other 2 either have another firered or leafgreen give you the other 2 or take the purified ones from Pokemon colosseum.
No
The only way to get the Legendary Beasts in Pokemon Pearl is to find them in FireRed, LeafGreen, HeartGold or SoulSilver, catch them and then migrate them over to Diamond via Pal Park.
