lugia,groudon,rikou,entei,suicune,moltres,articuno,zapdos and mewtwo
You can catch the 'legendary dog' Pokemon on Pokemon gold version
Raikou - Electric (has good speed and special)
Entei - Fire (lots of HP and powerful attack stats.)
Suicune - Water/Ice (good normal and special defence)
They can be caught either by using codes or wandering in grass in any place. They are able to appear at any timeduring gameplay while in grass.
All three are pretty good Pokemon, if not rather similar to the earlier eevee evolutions (Jolteon, Flareon, Vaporeon). If you can wait long enough to find them all, they're worth it ;)

You can if you want to it's totally up to you i can say yes that's the best suggestion considering they overpower most regular Pokemon however if you want to prove yourself a true trainer you will not use any legendaries.
Most Pokemon will breed with ditto. You might need to catch another one because they probably don't like each other. Only legendaries and genderless Pokemon won't breed with ditto.
