I am currently fostering a 4 month old gsd puppy. We have only had him a few days but he is painfully thin. My best guess is a 3 on body condition. You can see every single rib and his hip bones. We have switched him over to the good provided by the rescue - Diamond puppy. My best guess is that he needs to gain 10 pounds or so. We are currently feeding her per the recommendation on the bag (3 1/2 c) but he is soooo hungry still. I don’t want to over feed him - we finally are having solid poos as well. Could I up him to 4 or 4 1/2 cups? And if so is it best you feed more at morning or night? We are currently feeding him 3 times a day as well. Thanks!
