A full reading for Rat × Capricorn meeting Dog × Virgo 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 weight of the world rests on the Dog/Virgo's shoulders, and to you it feels just fine. After all, if you don't take care of everybody, who will? Be careful not to allow your tendency to focus on the abstract ideal (like a typical Virgo) of loving all of humanity sideline your more mundane and practical efforts to help the bum on the corner. You're a born Canine worrier, but that's how you get things done, so this tendency shouldn't add to your worries.
