Lifetime puppy food is what the owner of the farm where I got my pup from fed their dogs. So I continued to feed him this kibble, which I buy at the feed store. Vet recommended a large breed puppy food, Enzo is 3/4 Bernese Mountain dog, 1/4 German Shepherd. The bag doesn't say it for large breeds but it comes in 25 lb bags, so ..... The nutritional analisys is good, overall ingredients seem great without much filler. Only concrete basis for the 5 star review is 70 lbs at 4 months and that's enough for me.
