Dry dog food would be enough. But goats milk is safe for dogs, so if you do decide to give some it should be a very small quantity with some water. The idea is to give them the nutritional value but without compromising on their health. Puppies do learn to grow with what they’re given so don’t make it a habit for the pup. You can also give wet food as well made for pups in case you wanna give it a try, but usually the pup gets used to having the dry food only.
