I know of two lovely imports who became sterile in just the way that I describe. I agree that there is some skill required in the collection and placement of the sperm, but our repro vet is nearby and has even been known to do housecalls. My experience with AIs has been fairly limited, but one resulted in four pups and one resulted in 8 pups. I prefer for our boys to breed naturally within our own population of girls, but I do worry.....perhaps unnecessarily....about them breeding girls from other breeders. Myra
