> why dont the owners arrange for the dogs to stay together for the length of the season so they can mate rather than pinning all your hopes that a mating or slip mating on a certain day/s works and she has been caught??
Often they do, well not the whole season but from the earliest likely time until they have been mated several times.
I have twice stayed over a week when mating my bitches abroad.
One very kind stud dog owner had my girl for a month as she had a split season.
At other times I have had the stud dog stay with me or the bitch has stayed away with the stud dog owner. This used to be normal practise.
Many people may not now have the facilities to have a bitch come to stay or be willing to allow their dog to stay with the bitch owner, and some bitches would not do well away from home and their owner, ditto for the male who may not 'work' so well in a strange place.
Good breeders are less likely to use a convenient local dog, so long distances to travel are very likely, so with the cost of fuel many prefer to spend the money on ensuring the journey is not wasted by pin pointing ovulation.
