Hi,
What a shame

- you can find more info on www.baytril.com, but it does seem to be OK for pregnant bitches from the little I've read.
I would agree with the other posters - the stud has done his job, there were 3 puppies born even if only one is surviving, and no saying what the reasons were. No doubt that the stud fee is payable, and a puppy was the agreement.
All your sister's friend can do is offer to pay the equivalent stud fee/price of the puppy and hope that the stud owner is either sympathetic or doesn't want the sex/colour/quality that remains.
Easy to be wise after the event, but one very good reason to ensure that stud fees are ALWAYS paid up front - no way I would go through the hard work/trauma/possible expense of a whelping and have someone else with first call on the results.
Hope it works out well and she gets to keep the pup.

It is better to stay silent and be thought an idiot than to open your mouth and remove all doubt.
