When my dogs were pups, I fed them Nutro puppy food
for large breeds.
The food they eat now is Canidae, which
is a human grade dog kibble. (I also mix healthy people food
with their kibble.)
Learn to read the first few ingredients on the dog
food bag, the first 3, I believe are the most important.
So you want to make sure the first ingredients are
the most valuable. I am sure their are many good
qualtiy dog foods out their. Each dog is different,
iIF your dog looks and is healthy on the dog food it's eating,
than I would stick to that food.
