Hi, I agree with Brainless that a free return is often offered if the first attempt is unsuccesful, but this is the sort of details which should be discussed and agreed (preferably in writing) at the time of arranging the dogs services. You should first try approaching the dogs owner, and ask if a free return is allowed. And then, as advised above, on your next attempt consult your vet and have Premate testing done to confirm the time of ovulation/optimum mating days. However, if the breeders terms are payment upfront, only 1 service, you simply have to pay up again next time, with either this or another dog.
