I've heard of many people bringing up pups on the raw frozen with great success. You could use their interactive feeding guide on their website - that would probably be easiest for calculating the needs. I just calculated for you and it appears the pup would need about 2.4 oz. of raw based on current weight. I wouldn't feed at 2 am. I would try to feed 3-4 times during the day at first.
Sensitivities to hypogly are different for all dogs, so you'd have to see. At that age and weight (this was my Marcel's weight at 16 wks) - if it were me, I would supplement for the first week w/ Nutrical right upon waking and right before going to bed - so that both periods are covered. Nutrical can be used as a daily supplement, so don't let anyone tell you it is only for emergencies, bc that is not true. Read about first.
