The NB is nutritionally complete and balanced so if Cody is doing well and you want to keep him on that formula, go for it. Although I personally like to rotate various proteins, I certainly don't think it's necessary in order to have a healthy dog....I wouldn't think that there are any negative effects from just eating the same food all the time as long as it is nutritionally balanced (which these kibbles are). Especially for some dogs that require a special and/or strict diet...they can thrive on the same food for a lifetime.
My parents have fed their beagle the Natural Balance LID for several years...they rotate between maybe two or three different formulas and Mindy always has done well (she's a pretty sensitive one dog)...as long as my parents can get this food, they will feed it because it agrees with her and she enjoys it! |
