you can't catch all the legedary dogs on leafgreen you only catch one and get the others by trading.
you have to catch it in firered or leafgreen and transfer it to the pal park via the dual slot

None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
You cannot catch Registeel in Pokemon LeafGreen. This is due to FireRed and LeafGreen being able to trade with Ruby and Sapphire. Pokemon Ruby and Sapphire have the three legendary golem Pokemon including Registeel.
