I have a bitch that produced 9 pups in 6 hrs a few days ago and most of the time I just watched on the CCTV . I popped in at intervals to provide her with a warm drink and have a quick look at the pups but left her in peace to bond with her pups as much as possible .

With the CCTV you can easily see if the bitch needs help but few do .

Some years ago I whelped a bitch that had rejected her first litter because she had become so stressed out by people going in to cuddle the pups . They ended up having to hand rear them .
I left her well alone , and apart from giving them a fresh vet bed when she'd finished whelping didn't touch the pups at all until they were ready for worming and she was a perfect mother to them . I watched her on the CCTV so I could intervene if required but she managed fine on her own .

Healthy pups feel surprisingly heavy for their size and have a solid feel to them . If you are concerned about a very young pup and it feels a bit limp or chilled or hasn't got a full tum then you've got a problem otherwise I leave well alone .
