You do not say what is normal puppy tins?  If they are hungry they are not getting enough to eat.   I like to use a puppy porridge offered 4-5 times a day, Pedigree and Eukanuba both make one, spread the meals out over the day, starting early morning and the last one late at night.   Amounts are difficult to say without knowing how much milk they are getting from mum and what size of breed are they.

Aargh, mine aren't even born yet and I'm trying to remember all this sort of stuff! :-p

You will get plenty of support on this forum - no need to worry whether you can remember it or not :)  :)
