I think all this is more down to me being older!!!!! LOL. Years ago scanning wasn't felt necessary. It seems to me that all this has only happened in recent years. I have had small litters that could have 'sat' but fact is if mine went over by more than a couple of days (and yes, mine tended to have inertia) I'd take them to the vet, so there was no chance of any losses because the puppies just sat.
And yes, I have, since coming back to the UK, met up with some dreadful vets - how about one who didn't do a C.Section when I'd taken my bitch in for one, leaving it OVERNIGHT for the locum vet (the vet I normally used at that practice was on holiday) to open my bitch up. She'd shut down. Of the 9 puppies she should have had, only 5 survived, and one was lost shortly afterwards, with the milk they'd been trying to give them coming through his nose. We sued and voted with our feet. With hindsight none of this should have happened, but at that point, I still trusted vets!!!
On another occasion, my bitch was in trouble which went on for a year before we finally lost her. I was told SCANNING was enough. This wasn't a pregnancy btw. I took two outside opinions, including my previous vet up country (13 years and I had found a super one by then) who said she'd have x-rayed by then and probably opened her up. Ditto with the other vet down here. I went back to them and at that point the Sen.Partner appeared on the scene, did the x-ray and found her chest cavity riddled with tumours. Secondaries. I stopped counting the cost after it hit four figures, messing around. We'd probably have lost her in any case but what we all went through before the end, has to be seen to be believed.
But all this happened way after I'd not felt the need to scan for a pregnancy. Obviously if anybody finds a good vet, hang onto them!!!
