Dog/Capricorn and Dog/Aries meet at 82–87%, the corseted Canine encounters the stern self-assured Dog/Aries. Both halves take loyalty seriously. Both halves carry austere standards. The Aries fire warms the Capricorn corset, slowly, if Dog/Aries can resist riding the Capricorn for stiffness.
Chemistry is reserved and gradually warmer. Dog/Capricorn brings the canon-prescribed candy-and-flowers reluctance; Dog/Aries brings the Ram intensity and twinned-souls devotion. The bedroom requires Dog/Aries to coax Dog/Capricorn out of the whalebone corset. It can work, slowly.
Conversation is direct on Dog/Aries's side and stiff on Dog/Capricorn's. Dog/Aries declares; Dog/Capricorn intimidates with silence. The risk: Dog/Capricorn's quiet regard can read as withholding, and Dog/Aries's verdicts about inconstancy land hard.
Friction lives in pace and judgment. Dog/Aries plays matchmaker; Dog/Capricorn quietly disapproves of half the matches. Dog/Aries rides Dog/Capricorn for emotional inconstancy that doesn't actually exist, Dog/Capricorn just shows it slowly.
Dog/Aries learns from Dog/Capricorn that quiet devotion is real loyalty, even without declarations; Dog/Capricorn learns from Dog/Aries that uncrossing the legs and living a little is the canon's exact prescription. Both halves loosen each other up.
At 82–87%, this is a solid, slightly austere pairing. Dog/Capricorn and Dog/Aries build a loyal, well-disciplined life. Add looseness on purpose, neither half supplies it accidentally.
