One of my girls did this and it went on until the pups were 3 weeks old!
I had to hand feed her 1 nugget at a time - Very time consuming but the only way to get her to eat. She would happily eat a whole bowlful if we did 1 biscuit at a time but if I put the bowl in front of her she would just sniff it and look at me in disgust eben though it was exactly the same as what I was feeding her.
They all have their own strange little ways!!
