I found this too when I tried it, and noticed that it was only jilk and cereal, and I had already tried them on puppy milk and soaked puppy food (which does contain meat) and made that into a porridge.
so I would just soak a little of their food and mix it with puppy milk into the thickenss you wnat leaving it gradullay thicker until pups have their food semi dry, and the puppy milk as a drink a ocuple of times a day.
Mine are 7 weeks today and theya re getting half a pint of puppy milk between the four twice a day, and puppy ffod moistened with some water 4 times a day.
