Again it all depends on ur dog, whether it can adapt to d food or not, v tried Blackwood Catfish & Potato, too bad it contains duck meat, that makes my dog itchy n turn skin pinky all of a sudden. No choice but to feed Purina Salmon, v know Purina is not a good choice but switching d food now n then dont make any good either. So once u think u have made up ur mind n see good coat and poo that is in good condition then is ok liao.
