  I feed my dogs grain free food also.  I feed them what the bag says to feed their weight:  1/4 - 1/2 c. a day for 0-5 lbs.;   3/4 - 1 1/4 c. for 10 - 20 lbs.  I just checked the bag.  Their food has 416Kcal/cup. 
I didn't check it on a dog food calculator.  Duncan seemed to be gaining enough weight and Elliot doesn't seem to be overly hungry so I figured they were getting the correct amount of food.   
I looked at the pictures you posted of Bruiser.  To me, he does look thin in the pictures but then, I am used to Duncan who is almost 12 lbs.  Elliot is 4 lbs. but she is pretty small; her legs are half the size, maybe smaller of Bruiser's legs.   
I always treated my dogs like kids.  If they were hungry, they would let us know.  If they didn't want to eat anymore, they were full.
