I find it perfectly natural for my small breeds to whelp anything up to a week early, so no problems there.
By 8 days their natural maternal instincts have kicked in, so if your girl is showing no interest, I would be wondering if something is amiss. Was she vet checked after the whelping? Did the vet check the pups palettes?
As to feeding, mine would starve rather than get out of the whelping box, and I feed them by hand, or hold the feed bowl under their chins, tempting them with freshly poached white fish, chicken, scrambled egg, pilchards.
Totally agreed on the Evaporated milk. Diluted with warm water, I hold that under their chins, and find that they will lap up huge quantities, as long as they are not expected to move.
Only the very tiniest I have bred put on three quarters of an ounce per day. Up to an ounce is more usual. If your girl hasn't got much milk, those pups need to be suckling to bring it on. Have you tried latching them on? I will do my utmost to get them to suckle, rather than supplement. I prefer to put all the nutrition into my bitch.
Let us know what your vets comments are. Good Luck. Jean
