Mix 10 ounces goat's milk or evaporated milk, 1 cup of plain full-fat yogurt, 1 raw egg yolk and 1/2 teaspoon corn syrup to make puppy replacement milk. If using evaporated milk, it is also necessary to add 3 ounces of sterilized water. Mix the ingredients together with a wire whisk, place in a storage container and fill bottles to feed the puppies as needed.
This formula can be stored in the refrigerator for up to 7 days. It is necessary to warm the milk up to body temperature before feeding the puppies. Discard any formula left in the bottle after each feeding.
