we have tried science diet, bil jac and she is currently on royal canin.i am happy with the ingredients in the food, and the price (imo) is not much more than i pay for royal canin. royal canin costs me 36$ plus tax for 36 pounds, so you figure 1$ a pound. the flint river ranch is 40 lbs for $60 no tax no shipping cost.so that comes about to about 1.50 a pound and since i am supposed to feed her less of the new stuff it will last longer ( i am hoping! ) :roll: . the only thing i really am worried about is that it might be to rich for her.these darn food issues are so stressful!! :x
