Mine get about 4 times their normal dry rations soaked so they can hardly hold any more water.
This I hold under their noses so they don't have to leave pups at all.
If she wasn't off her food before whelping then this will normally work well.
In the case of a bitch who was eating poorly (hadn't eaten at all for two days even when I steamed salmon) I went to Wilkinsons and got a tray of their cheap yellow label cat an dog food (as it didn't list cereal) and she ate 4 tins of that a day, (liked the cat food best) and her poo stank, but it got her eating, next day she got three tins and one ration of usual food and so on until I was just giving a spoonful of the vile smelling stuff, and she was eating the soaked kibble.
She will still be tired an sore from the C section, and of course nursing takes it out of them, which is why we support them as much as possible, and are at their beck and call ;)
