My girlfriend is a Sagittarius dragon and I am a Aries tiger are we compatible?

Both of you are very capable and have a strong desire to take control. Each of you is independent in thinking. Once there is an opinion difference, it is not easy for you two to convince each other and the discussion may come to a quarrel at last. Compromise is the key to make this relationship last. Both of you need to learn to make concession for each other. In this way, this relationship is going to work out well.
