Whenever possible chilled semen is preferred due to a better conception rate and lower cost overall. The success of frozen semen breedings depends on three things; 1 quality of the frozen semen 2 timing of the insemination 3 fertility of the bitch. Frozen semen can be sent to VMC several weeks prior to the breeding; we can store the semen until it is needed. The semen owner will need to order the shipment and the bitch owner can coordinate shipment payment. If semen is stored at Zoetis in Kansas City, MO please contact them to complete the paperwork to request the transfer. We accept frozen semen shipments routinely on Mon-Sat 8am-5pm.
