I use the Orijen, Large Breed, Puppy food. Finn has eaten it consistently for the past year, so I didn't mess with changing it.
Find a quality food that they eat and stick with it, until there is a clear reason to change it.
We started our guy on Orijen small breed and switched to the large breed after a couple of weeks just because hand-feeding him from time to time was taking aaaages with the tiny biscuits 😂
He's been happy with it for nearly 2 months now, is gaining weight steadily and the larger size gives him something to crunch too instead of just swallowing the biscuits whole.
