I feel this is highly unlikely as the semen is evaluated before being sent. No one is going to send a *poor* sample knowing the bitch is unlikely to get pregnant! The ones I've done have come with the semen evaluation form. I use Dr. Hutchison's office which is one of the best in the country. They have a higher rate of conception with chilled than with natural and slightly more puppies per litter with chilled than with natural--over all breeds. However they have had few successes with Cavaliers--in fact maybe only one so far. They do it the same way for all. I can't help but wonder if something isn't different with Cavaliers. I have progesterone tested many, many bitches over 5 years. I have yet to see many strange numbers from the lab results. The numbers seem dead on, progress very nicely and with natural breedings done after the bitches hit *5* virtually always result in pregnancy. The few bitches who had weird readings or did not get pregnant nearly always turned out to have a problem of some sort and either never got pregnant or took some *work* to get pregnant.
