The dog has evolved as a carnivore with a natural need for nutrition with varied fresh meat and fish supplemented with small amounts of vegetables, fruits and grasses. Acana Heritage is made largely from nutrients naturally present in the ingredients; synthetic additives are kept to a minimum. Young dogs need a protein-rich diet during their short growth period. For this reason, Acana Heritage Puppy Small Breed consists of 70 per cent high-protein ingredients; free-range chicken, free-range eggs and wild-caught flatfish. Puppy Small Breed is suitable for puppies weighing up to nine kilos when fully grown. For medium breed puppies there is Acana Puppy & Junior Heritage and for larger breeds Acana Puppy Large Breed Heritage.
