How long have you soaked it for and did you cover the food to keep the steaming.
With some foods you need a couple of hours at least.
Do not add milk to the food until after is has been mashed as it will not soak.
Never used that food, but the Arden Grange puppy soaks easily as does Autarky puppy, James Wellbeloved puppy, Vitalin puppy etc.
