For 1 week we feed our 7-year-old German shepherd, the wolf blood Wild Duck kibble. But we have started the diet change slowly, ie in the morning, the "old" and in the evening the "New." She tolerates it wonderfully and used it excellently. The legacy is very low, which in other dry food is not always the case. Moreover, it is correct then greedily. We can highly recommend the food, the price is indeed high but there is very economical.
