Eukanuba Large Breed Puppy provides complete and balanced nutrition for large breed puppies. Puppies have different needs than adult dogs. Relative to their size, they need more energy. Their muscles and bones are forming and strengthening. Their digestive systems are more sensitive. Their immune systems are still immature. And their minds are still developing. Eukanuba puppy food provides the balanced nutrition that can help them thrive-now, and for years to come.
