Is there an all life stage dry dog food designed for large breeds, with larger nugget sizes? Should I be feeding my 12 month old great pyrenees/anatolian shepherd large breed puppy food since technically he is still a pup? Just rescued him. When actually being fed, he was fed a crappy dog food that at least had perfectly sized nuggets.
At a year old, you can usually feed whatever you want. If, because of his circumstances, you feel he still has a lot of growing to do, not just maturing, but actual growth, then you should definitely keep him on a food for large breed puppies. NutriSource Large Breed Puppy has the appropriate calcium levels, is economical, is well tolerated, and is easy to transition to.
