easy way to catch it is masterball but if u already used it use scary face or a wobafet then hypnosis and lower its hp with a sythers or a farfeched false swipe and use ultra balls.
Trade from Pokemon leafgreen or firered
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
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.
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!
You cannot catch the legendary dogs in Diamond or Pearl, you must migrate from Pokemon LeafGreen, FireRed, Colosseum, or XD.
transfer them from Pokemon coliseum or xd
dont think
migrate from firered and leafgreen
gatch them with a master ball but trade the master balls
You have to use the action replay to catch them.
no you cant and how would that even work.
Pressing buttons will not help catch Pokemon to improve chances, lower the health and put status' on it like sleep or paralyze and use watever catch balls you have. For legendaries save before you face them so you can face them again if you fail somehow. Do not use your master ball until you run into the legendary dogs.
