Manipulation, anyone? The Scorpio side of you is always out for number one, and the amazing quality of your self-aggrandizing tactics is that you so often get away with it by means of your Rat-induced radiant personal magnetism. Direct and forthright, you manage to defuse animosity by making no secret of what's in the deal and for whom. Others can respect such a straight-talking competitor; even if the Rat/Scorpio's concomitant razor-sharp wit and acid tongue can sometimes keep potential allies at bay unless kept in careful check.
Don't go so far as to try to catch a Frisbee in your teeth, but to all lesser extents an interest in physical exercise is definitely encouraged. The Dog/Sagittarius should let their play become their work ever so slowly, without relinquishing a sense of fun -- which can be life sustaining both for your inner Dog and for all the others who count on you to show them how to have a good time.
