seems like you got responses on this issue on another thread. even wellness themselves warn against feeding their grainless product to puppies, and you know they want your business/$$. i think they took a responsible approach to this, at least compared to some other producers. this is from the faq section on the wellness site:
I have heard that some of these high protein diets can’t be fed to large breed puppies. Why?
Research has shown that large breed puppies should not be fed a diet that is over 1.3 – 1.5% Calcium or they run a significant risk of developing bone abnormalities. Many of the high protein diets on the market today are well in excess of 1.5% Calcium. We do not recommend any large breed puppies be fed our CORE dog diets, or any of the other high protein diets on the market today. In fact, we would conservatively say that puppies in general should not feed higher protein diets that exceed 1.5% Calcium. Again, this is why we feature a maintenance claim and promote the diet for dogs over 1 year in age.
you are feeding wolfcub, and even solid gold discusses this in the description of this food:
High energy diets, like most puppy foods, can promote rapid growth in large breed puppies, which can play a role in the development of orthopedic diseases. WolfCub Large Breed Puppy Formula contains a lower amount of protein, fat, and calories than Hundchen Flocken Puppy Food to help control the growth process. Research shows that a Calcium level of 1.5% or less is the most suitable for a large breed puppy.

barb did a nice comparison on a grainless kibble vs a non grainless kibble (canidae) in the other thread:
