Editor's note

Two opposite philosophies. Canagan is grain-free, 34% protein, free of artificial additives and suits all life stages. Royal Canin contains grain, is 25% protein and adult-only, but costs under a third as much per 100g. Canagan if a vet has confirmed a grain problem or you want more animal protein; Royal Canin if you need something you can sustain.
