                            based on being formulated to meet the nutrient content  of the  Dog Food Nutrient
                            Profile for Growth and Reproduction.
                                Because of concerns for excess calcium to produce detrimental effects in growing
                            dogs of large and giant breeds, 10-13  the 2007 CNES deemed that additional restriction to
                            the  maximum limit  for calcium  was  warranted and  lowered the  maximum calcium
                            concentration to 1.8% DM.  The CNES did not believe it necessary to decrease the
                            previous maximum calcium concentration of 2.5% for adult dogs or growing dogs of
                            small or moderate size breeds.  However, the AAFCO Pet Food Committee felt that
                            only one  maximum  value should be established,  especially to ensure all life stage
                            products were properly formulated.  Thus, the AAFCO Pet Food Committee elected to
                            set the maximum calcium for all dog foods formulated to meet the Dog Food Nutrient
                            Profiles at 1.8% DM.  The CNES retained the maximum phosphorus concentration of
                            1.6% DM for both profiles, as well as the minimum and maximum values of 1:1 and
                            2:1, respectively, for the calcium to phosphorus ratio.

                            OTHER MACROMINERALS
                                POTASSIUM
                                The 2007  CNES  elected to retain the recommended minimum potassium
                            concentration at 0.6% DM for both Profiles.  Although the RA in the 2006 NRC and
                            some concentrations in the FEDIAF Guidelines are less than 0.6% DM for potassium,
                            the  CNES  felt that the potassium concentration did not  warrant changing especially
                            given that potential toxicosis of potassium  was  not a practical concern.  Thus, a
                            maximum concentration for potassium was not established.
                                SODIUM & CHLORIDE
                                The 2007  CNES  did not change the  minimum recommendation  for sodium or
                            chloride in the Growth and  Reproduction Nutrient Profile as the values are  slightly
                            above the 2006 NRC RA.   The 2007  CNES  made an editorial increase in  the
                            recommended  minimum concentrations  for sodium and chloride in the  Adult
                            Maintenance Nutrient Profile to match the 2006 NRC RA.  For sodium the increase
                            was from 0.06% to  0.08%  DM and for chloride from  0.09 to  0.12% DM.   The
                            recommended  minimum concentrations  for sodium and  chloride in both dog  food
                            nutrient profiles continue to reflect the 1:1.5 sodium to chloride ratio of salt previously
                            used by the 1990 CNES to justify recommended chloride concentrations.  As noted by
                            the 1990  CNES, because palatability and  food consumption  would decline due to
                            excess sodium before adverse health effects  were observed, setting a  maximum
                            concentration for sodium was not of practical concern.
                                MAGNESIUM
                                The 2007  CNES  increased the  minimum recommended concentration  for
                            magnesium from 0.04 to 0.06% in Adult Maintenance and Growth and Reproduction
                            Nutrient Profiles to match the 2006 NRC RA for adult maintenance and peak lactation,
                            respectively.  The 2007 CNES deleted the maximum recommended concentration for
                            magnesium due to lack of data specific to dogs in both the 2006 NRC and the 2005
                            Mineral Tolerances of Animals.  The only comment regarding maximum magnesium
                            content  in the 2006 NRC  was that a SUL  for  magnesium in the diets of dogs  was
                            greater than 1.7% DM.

                                IRON
                                The 2007 CNES made an editorial change to the minimum concentration for iron
                            in the Growth and Reproduction Nutrient Profile to make the concentration consistent
                            with a presumed caloric density of 4000 kcal ME/kg DM  which  makes  the
                            recommended concentration  consistent  with the  RA  from the 2006 NRC and the
