We recommend that a newborn puppy or kitten be fed 2 tablespoons of ready to feed liquid or 2 tablespoons of reconstituted (water added to the powder to make a liquid) powder milk replacer for every 4 ounces of body weight over a 24-hour period. For example, if your puppy weighs 8 ounces it needs to be fed 4 tablespoons of formula over a 24 hour period.
