Hi aaron s:
There are several reasons reviews can change over time. One possible reason is that the animal protein content in the individual recipe may have changed between reviews.
Not sure what date you are questioning. The original review for this specific Diamond line was posted on DFA 01/05/2010, the last update was on 04/10/2014. Are these the dates you are referring too?
Check out the FAQ section, specifically “How We Rate Dog Food” on the review side. Hopefully all your questions will be answered after you read it:
