Hi Debbie-
With a growing large breed the first and foremost important thing is that the food is nutritionally sound and secondly that it provides the proper calcium levels and a proper calcium to calorie ratio.
Pro Plan Large Breed Puppy may have ingredients that most on this site deem less than desirable, however it is a nutritionally sound food that is feed trialed on large breed puppies and provides the correct calcium levels, along with the proper calcium to calorie ratio.
Using consumer reviews to judge the quality of a food is going to leave you more confused about which food is right for your dog then when you started. Emotion plays too much of a role in most pet parents choice of dog foods and they can be swayed very easily by a nice looking ingredient panel and not question for a moment if the food even provides the proper nutrition for their pet, assuming that if the ingredients look good the rest will fall into place. Find a food that your dog does well on and enjoys eating that meets the needs of a growing large breed.
If you still do not wish to use ProPlan or Nutro, some other foods that I can suggest are:
Fromm Gold Large Breed Puppy
NutriSource Large Breed Puppy
Precise Holisitic Complete Large & Giant Breed Puppy
Solid Gold Wolf Cub
Eukanuba Large Breed Puppy
Hill’s Ideal Balance Large Breed Puppy
