Hi Kathy-
The last Zignature rep I spoke too told me Zignature was in fact appropriate for large breed puppies. However, this guy was also not extremely knowledgable about pet nutrition in general, so I doubt I trust him.
Best thing you can do is to email Zignature directly. Ask them for a full nutrient analysis of whichever Zignature formula you want to use and then take the kcals, calcium and phos levels and input them into this tool here: /best-dog-foods/best-large-breed-puppy-food/
PLEASE NOTE* You will need to be very specific with them as to what you want in the email. Tell them you do NOT want the values of calcium and phos that would be found on a guarenteed analysis as that does not tell you anything. Ask specifically for a TYPICAL or NUTRIENT analysis.
You can post your results here and I will help you determine if the food is appropriate or you can read the article and see if it is for yourself.
