(My apologies for any bad spelling)
I love the Iams Company. There are a lot of people here who have no idea what their talking about, especially with by-products! Yes, some by-products are not safe or cleaned for that matter but not all by-products are created equal! The By-Products (Which contain high quality protein) used by the Iams Company (Which produces Eukanuba as their premium brand) always uses clean, cut chicken cartelidge and intestins! They do not use BEAKS, FEATHERS or any other un-usable source in their nutrition.
I personally believe that their are few brands that compare to the quality in Eukanuba!! And as for IAMS, they shouldn't be degraded in a grocery store! IAMS & Eukanuba has CHICKEN or LAMB as their 1st ingredient in every formula and all those other brands which are in grocery stores NEVER have CHICKEN or LAMB as their 1st ingredient! Its usually Ground Yellow Corn. And that goes for Purina, Kibbles n'Bits, Pedagree & every other brand out there!
High quality Chicken/Lamb based Proteins, Omega 6-3 & vitamins & minerals should be listed on every dog food formula. Also, Denta-Defense (Micro-Coating which is used to remove tartar) used in ALL Eukanuba brands is also important. Its proven formula i believe is super important as well.
I would recommend any IAMS/Eukanuba brand to anybody who truly loves their pet!
