I personally think Brembo looks awesome for his age, they all go through a 'gangly' stage, some more than others, don't sweat it. Brembo looks amazing compared to Pookie, whom for a while looked exactly like a boxer puppy! When I got him he was being fed RC too. He was soooo fat. And roly poly. His name from the breeder was FAT BOY!
Fromm is more LEAN and BETTER for your dog!!! BETTER for his health.... number one thing, all the rest of that stuff is FLUFF! It will fill in eventually. I think what she is talking about is FAT. Your puppy does not need carbs (aka fat) to grow! That is nonsense. They need protein, vitamins, and minerals!
