I have usually planned a specific mating a year or even years ahead, especially those involving overseas participation.
If the stud dog owner wasn't absolutely delighted and on board I wouldn't' be suing their dog, as it will entail quite a bit of commitment on their part. In both my cases it meant putting me and my bitch up for 8 - 12 days, picking up from airports etc.
I have my own website and usually have my future plans up so that others are aware in case they may fit in with their plans as we have a numerically small breed with shrinking gene pool so you do need to know what others are doing.
For example on one litter I changed the stud I was using as another breeder had used him on a bitch of very similar breeding and i didn't think that would have benefited the gene pool as well as me using an alternative dog.
Of course if plans change then they change.
As far as specific litters the plan would show when the litter was likely, and I would expect to have some bookings before the season. I then write to all when bitch comes in season to confirm their interest, same when bitch confirmed in whelp, and then once born.
At this point (some disagree) I charge a £50 deposit to confirm a booking which is non refundable unless I cannot supply the puppy for some reason. This helps avoid time wasters and speedily sends surplus enquiries to another breeder, in time to get on their waiting list, so avoiding too much uncertainty and disappointment .
We have a breed with a low of only 33 puppies registered last year, with 98 the year before.
