Is it ok to feed a 4 month old puppy wet adult dog food?

It`s ok, but be aware that any new foods given to a puppy may upset its digestive system and give it diarrhea if the change is not gradual.
If your pups are used to pedigree wet puppy food then just mix some of the adult in with it. Or mix a little with their dry food, which is best dampened down a bit at this stage in pups life.

Wet food has very little nutritional value as it's 85% water, why pay for water when it can be gotten for free from your tap?

Any diet changes must be done gradually over a period of ten days to two weeks, otherwise you may cause serious intestinal upsets.

As a one time thing, no - but I'd suggest mixing it with their regular food so you don't create any tummy upsets.

yes, one meal will not hurt them but may give them tummy troubles.

DO NOT IT CAN HURT THEM SEND THE DOG FOOD BACK AND GET PUPPY FOOD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
