> I'm a bit surprised mixedpack. The practise I use will only allow 2 jabs of oxytocin.
With one of our litters, which was whelped in my vet's office overnight (out in Canada that practice was a distance away so I camped out there - vet lived in the apartment over his Practice), if it went a long time with nothing happening, I'd phone up for him to come down, check, and give another oxytocin shot pretty much to produce each puppy. Very fraught. On the other hand, another vet (we'd moved) gave me two jabs of oxytocin to come home with, having checked my bitch. I gave her one, nothing so not liking doing this myself in all truth I took her back and they did a C.Section.
When I read this question I thought human Gran

To be honest, much as clearly this works with some bitches, I didn't have ANY of our other hounds anywhere near mum and her puppies, for the first 3 weeks after which the box was moved into the kitchen and another section added for more space, and they were able to get used to the normal household comings and goings. They were still not WITH the others and certainly none was IN the whelping box!!
If you can get away with this without upsetting mum, or getting into a fight situation, so be it. I'd just not allow that, in case.
