Well......although I've always been there watching like a hawk, never interfered unless there is a problem, every dam should get to do what nature intended, if they fail, then we step in....... my foundation breeder would have been slapping your hands if you'd gone charging in to open sacs and do the cords, and then moving them around during whelping, could cause untold stress to the dam
I know there are another school of breeders who leave the bitch to take care of everything themselvesGosh, that's not old school, that's normal!!!

Where has this new wave of thinking (not met any breeders who take control like this yet) come from?.......... you may expect from a veterinary doing a c-section I guess.
Ce la vie, I guess, but would never deny a dam from looking after her own pups like this.
