A day later i informed the breeder of this and she was sad about what happened.This was the perfect opportunity for the stud dog owner to have offered another mating, but it appears that did not happen? It is down to each stud dog owner how they work.
These things are generally discussed prior to mating and most stud dog owners will offer two or three chances to make pups happen, alas here a pup
did happen, in all respects the service of the dog went to plan the sperm made a pup and was paid for, the stud dog owner may well now feel that the fee is fulfilled, (and to be honest it was) unfortunately the pup was still-born (did resuscitation take place, often pups can be brought back?)
So, as much as many stud dog owners under the circumstances would feel upset and wish to offer another mating free, it is entirely down to that stud dog owner and it is not necessarily mean if this one says no....as a pup was produced, as sadly as this one went.
All you can do is talk to yours (nicely) and if they do not wish to offer a free service again (and I would also understand that) perhaps you can try to ask if they would be willing to give a small discount? If not, I guess you will have to pay again.
Just be polite and see what happens.
