I have seen no positive results from Beneful. And the vegetables wouldn't be too appealing if you saw them in the factory...

I would pick a high quality food that the pups do well on and feed to conditioning. You may just want to go back to whatever you were feeding. They probably will beg, but just don't give in. You can add some non-starchy vegetables to make them feel full. When they were being fed less and beging for more, were they losing weight?
