Generally they only need 3x a day for around 12 weeks (if i remember correctly).I wouldnt cram 3 meals into 2 because you would just be wasting food because they can only digest so much at a time.Basically all dog foods call for different amounts of food per feeding.So id just follow the recommendations on the bag.But give 3x a day instead of 2x.Maybee a feed when you wake up,another when you get home and another before bed.i dont know your schedule but id try something like that.We just had a litter of pups and they are 9 weeks now but i was having to wake up at 5 am for morning feed.lunch around noon and dinner around 8-9.
