>and stoped them feeding of the mother just wondering if that was the right thing to do
I wouldn't stop them feeding from their mother - they still need access to her for milk, comfort and training. As the amount of solid food they eat increases, the amount of milk they take from her decreases, so by the time they're rady to leave they've been naturally weaned, although they'll no doubt still be allowed a couple of seconds comfort suck right up to the day they go.
Personally I always add water to dried food throughout a dog's life.
