I would wean them to what you are feeding lactating mom. Soak the food thoroughly and let it sit in the fridge until you can easily mash it with a fork, even canned food needs to be mashed if it has lumps. Heat it up by adding warm water until you have a gruel, if the puppies need more calories you can use goats milk, and adding a dose of probiotics is a good idea. Test the temp before you feed. Puppies are extremely messy eaters, so put them where you don’t mind a mess to eat and plan on having to clean them up afterward. Start by only feeding them one small meal the first day or so, then 2 meals and so on until they are eating enough solid food.
