A full reading for Rat × Capricorn meeting Dog × Leo is on the way. In the meantime, the score above is computed from the canonical element matrix and sign-cycle distance, and the profiles below cover each side individually.
Power for its own sake, and the cold brutal solitary serenity that accompanies such an exalted position, are precisely what the Rat/Capricorn lives for. If they think they've seen goals-oriented people in action before, they haven't seen anything until they've seen the Rat in you breeze past them on your way to the top, in such a way as to make Genghis Khan seem mild-mannered, of whatever hierarchy to which you see fit to belong.
The Dog/Leo may be crispy on the outside, but they're chewy on the inside, eaten up as they are by a veritable army marshaled by fear and staffed by voracious, bickering particles of self-doubt. You're going to need someone who can take you out of yourself and make you forget your sense of Canine inadequacy, and then send you in to conquer with banners flying Leo-style! In the meantime, try not to huddle in the fetal position with your hands over your head.
