I was researching several dog foods in the “5 star” category, and I came across Primal Freeze-Dried Formula. I really love the ingredients and I thought I would switch my dogs over from Wellness Core. I am a bit confused however when I then read,”Primal Freeze Dried Duck [A]” and “Primal Freeze Dried Lamb (2.5 stars) [A]” for example. Now I know the [A] stands for “All stages of Life”. My question is, why does the dried lamb have 2.5 stars next to it in parentheses? Thanks in advance if you know the answer, and I hope this is neither a stupid question or a repeated one.
