on another forum, someone who others said was in the know said that Innova Evo was not good for large breed puppies, but was great after they finished growing,, but the person said Evo was good for small breed puppies,, they said that for toy breeds it was "ideal."
On that thread, someone posted that they had emailed Natura Pet, the brand that makes Innova, to ask about this, and they got a thorough email back which they posted, which i'll post here. I have heard once before, on this forum, that the company is great at communicating with dog owners who contact them, so it would always be valuable to call them directly and ask them questions about this unusual kind of dog food (Evo)--and then share their answers with us.
Here is the post--the person asked the company about feeding Evo to a large breed puppy who is already large. As you can see, the customer service guy does say EVO is an all life stages food that is appropriate for dogs that are not large breeds:
Response I got back from Innova on feeding EVO to a puppy:
Thank you for contacting us about our products. You should feed the puppy food until the reach their full growth potential.
The Innova EVO is balanced for all life stages, and therefore can be fed to puppies that are not large breeds.
Here is an excerpt from a letter our Vice President, co-founder, and nutritionist Peter Atkins wrote that might help to further define the Innova EVO and large breed puppies/dogs:
Q. Is EVO Dog Food appropriate to feed to my large breed puppy?
A. No. EVO Dog will tend to maximize growth. This could be harmful to the long term health and well being of your large breed puppy.
Q. Can I feed EVO Dog Food to my Adult or Senior Large Breed Dog?
A. Yes. Feeding EVO Dog Food to your adult large breed dog can work very nicely.
I hope I have given enough information to adequately address your query. If you have any further questions or need additional information, please feel free to contact me at your convenience.
Please reference the original e-mail when responding.

I think another problem with feeding puppy formulas is that the minerals and especially calcium might be too high, and maybe a problem with puppy foods is that different breeds or types of dogs may have different needs, whereas the puppy food is marketed to all dogs. I wish i knew more. I just have heard comments on the web but don't know the scientific foundation of any of them.
