they have to be migrated from pokemonSilver. they cant be found in emerald.
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
Unfortunately you cannot get the legendary dogs Entei, Suicune, and Raikou in Emerald Green. You can import them into Emerald green by trading from Leaf Green and Fire Red.
If You have The ROM i am pretty sure that not only the three Legendary Cats, but Zapdos Moltres And Articuno are in there too Suicune=Cheetah Entei=Lion Raikou=Tiger
IN the desert you can find the legendary dogs. Make sure you sty on the edges of the desert!!!!!!!!!!!!Important
The three legendary Pokemon in Pokemon emerald is Kyorge, Groundon and Rayquazer.
In general, there are 6 legendary Pokemons in Emerald. If you count the Event Pokemons in Emerald, then there are 12 legendary Pokemons in Emerald.
i do believe you can but you need gameshark so go buy one off of eBay their cheap
ho-oh did
You must trade it from Emerald. I'm afraid I don't know how to get it in Emerald. I think you have to complete the pokedex -_-
its not an emerald its RAYQUAZA the main legendary Pokemon in Pokemon emerald.
RAYQUAZA IS THE BEST or GROUDON or KYOGRE for Pokemon Emerald THE 3 LEGENDARY!
Ho-Oh and Lugia.Also the 3 Legendary dogs. Also I think Mewtwo and the 3 Legendary birds if you travel to Kanto later on in the game.
