That's a tough one! On the one hand I'd want to save any healthy pups but on the other hand I wouldn't want to risk them getting born only to suffer - through possible defects, deformities etc so I think that as hard as it would be I wouldn't allow for human intervention. I agree with you that it probably was nature trying to take its course and there most probably would have been something wrong with the pregnancy in the first place. But it would be an incredibly hard decision and if I was in that position then I may act totally different to what I think I would now! Anyway I'm sorry to hear that and I hope that the mother is okay and that there are viable, healthy pups that grow to be strong and happy! I wouldn't want to be there either though - I couldn't handle seeing dead or partially developed pups, it would be too hard to handle! Please let us know how it goes!!
