yes its ok to change....i had my baby on nutro natural choice, and now just switched to merricks puppy platter.......she lovesssss the merricks...and it is really good food. i also recommend califonia natural, canidae and wellness.....bella has been itching lately....i dont know if it is the food switch, so i am starting the missing link tomorrow and if that doesnt help i will be switching to one of those foods i just listed......
