Puppy food - advice needed please

[Newpupneeded]

Brought a new puppy home a couple of weeks ago, an 8 week old standard schnauzer.

Breeder sent home puppy food with him, Royal Canin (medium dog)

Firstly, the recommended amount seems massive - 234 grams - and he’s not eating anywhere that much across 4 meals a day.

Secondly, this is not rated very highly on All About Dog Food. (40%) compared to (68%)

Thirdly, do puppies really need specific puppy food?

After seeing it recommended on here, I now feed my other two smaller dogs CI Tickety Boo food, varying between meat and fish versions.

I do have some of their wet puppy food - only because that is all they have in stock and I have a fussy eater - is there any issues if I combine that with the dried food for the pup?

Dog food does seem to have got very complicated these days compared to my childhood dog who got tinned Pedigree Chum and biscuits!

I agree @tizwozliz that the difference is obvious. On paper.

We've always gone for quality. Our previous two dogs were on superfoods ranges and we've always done our research. Also looking into the DCM peas link, and considering the implications of fillers like beet pulp.

But this time around, we found that the best choice for us wasn't necessarily the best choice for the pup. It wasn't for lack of trying or a laziness on our part in relation to researching ingredients. It's just how it went.
