gatch them with a master ball but trade the master balls
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
No
You cannot catch the legendary dogs in Diamond or Pearl, you must migrate from Pokemon LeafGreen, FireRed, Colosseum, or XD.
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!
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 dont find the legendary dogs in fire red. instead you get the legendary birds. they are zapados moltres and articuno
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.
migrate from firered and leafgreen
find one then use pokéballs ofcourse!
articuno zapatos moltres and mewtwo
no you cant and how would that even work.
you have the best chance of finding and catching raikou(or any of the legendary dogs) on route 1.(use your master ball. raikou can run away.)
