Hello! I am new to this forum so look forward to some good info! I have started my 8 month old pup on Nutri Source Performance dog food, he was previously on Nutri Source large breed puppy as that is what he had from the breeder. My question is how much food does anyone that feeds this food give to there pup? The bag says to feed only around 2-2.5 cups but I was feeding 4 cups with the large breed puppy. He seems to be doing good with the 2.5 cups I have been feeding him but was just looking for others advise. Thanks!
