Hi - we've had a lot of C.Sections (probably too many although my bitches did tend to go into secondary inertia at the first feeling of pain! Bassets!!) but in every case, not until my bitches had gone into labour, getting nowhere fast. Yes, they were given pit shots to help things along, but I'd only do this a couple of times before asking my vet to go ahead with a Section. This wasn't a pre-planned C.Section, as obviously I'd always hope we'd get a natural whelping.
Once the puppies were safely delivered, ALL my bitches were excellent mothers. It was just the ouch mum they didn't always cope with. And again, nothing to with not being able to physically self-whelp. All in the mind. It's the same with mating with many Bassets. I was lucky to have one who helped himself, but most of mine needed us to assist.
ps To avoid a problem re staffing, I'd always phone my vet once labour started so they were ready if needed.
