Chewy is a picky dog food eater. I cant tell you how many brands we tried before I discovered Royal Canin for Yorkshire Terrier. He eats the adult version now but started on the puppy version.
It is specially formulated for the picky breed. Of course Chewy loves human food. He eats my salad fixings in the morning when I make my lunch - lettuce, arrgula, carrots, tomatoes, berries, etc.
