Here are a few altered dominant chords. These can be substituted for any functioning dominant -- any five chord going to a one chord.
Altered dominants are constructed by taking a V7 chord and raising or flatting the fifth, or raising or flatting the five. You would likely use the altered scale over these chords. The altered scale is essentially the harmonic minor starting on the seventh, one semitone below its root.
