I feed raw (not BARF) but I wouldn't suggest feeding it exclusively unless you really know what you're doing. You need to understand the nutritional requirements of dogs and puppies before just 'diving in', especially when rearing a litter.

If you want to feed a 'wet' food, Natures Menu complete is one of the better ones. Or maybe try a good quality complete with some meat added.

The problem with rearing pups exclusively on raw or BARF is that new owners will thenhave to continue and might not want to, or might not have the knowledge to do it properly. For this reason, despite feeding raw to my dogs, I rear my pups on complete.
