I have done shipped and frozen a few times....
I got a full litter breeding on a 21 at the time of surgical AI.
Vet has done all others a day after a 9 to a 14 and never got pups....3 frozen, 2 shipped. To be fair, the vet was NOT happy with the semen on the last one, and another breeder had also done 2 shipped fresh AIs without pups. I am afraid to do a shipped at this point, and would like to know if others have numbers that are a better fit for getting pups.....also, this vet does get alot of litters for other breeders on both frozen and fresh chilled....I have semen frozen from Xito Maineiche and Ufo v Guy's Hof and am afraid to even try again!
