The duration of copulatory tie varies widely based on individual health, breed, and ambient stress levels. Normal copulation proceeds through distinct physiological phases, transitioning from rapid mounting to a passive, reversed stance.
| Mating Phase | Typical Duration | Physical Characteristics & Behavior |
|---|---|---|
| Phase 1: Mounting & Penetration | 1, 3 minutes | Male mounts from behind; os penis allows quick entry before complete erection develops. First and second fractions of semen are released. |
| Phase 2: The Turn | 5, 30 seconds | Bulbus glandis engorges fully. The male lifts one hind leg over the female's back, standing rear-to-rear to face opposite directions. |
| Phase 3: The Copulatory Tie | 10, 30 minutes (up to 60) | Dogs stand locked tail-to-tail. Prostatic fluid passes through the tract. Both dogs remain calm unless startled or physically displaced. |
| Phase 4: Detachment & Recovery | 5, 15 minutes post-tie | Venous blood leaves the bulbus glandis; vaginal constriction eases. Animals separate smoothly. Male grooms penis as it retracts into the prepuce. |
During the turn, the male rotates 180 degrees so that both dogs face away from each other. This posture minimizes physical strain on both animals, letting them stand naturally without maintaining an awkward mounting position for half an hour.
