Don't ever feed a pup "as much as he can eat" as it can be VERY dangerous! Many puppies will just eat and eat until they get ill. At best it will cause diarrhoea and vomiting, at worst bloat and death. I have twice in my dog owning life had puppies manage to get into the food cupboard and help themselves -both nearly died. Even one of my adult dogs that once was given too much food and treats by a small child almost died (had to spend the night at the vets and it was touch and go, the vet gave him a 50/50 chance) as many dogs simply will not stop eating when full. (These 3 dogs mentioned were of 3 dfferent breeds so it isn't a case of just some breeds being greedy.)
There is no need whatsoever for a pup aged 7 weeks to have milk -they are by then weaned.
