Puppies grow at different rates. Giant breed puppies can take as long as two years to reach adulthood, even when growing as much as two kilograms per week, while small breeds can take as little as nine months. To get the most out of their diet, puppies must eat today for the dogs they will be tomorrow. Classic Puppy Large to Giant Breed’s premium formulation is tailored to provide pups with everything they need to get a great start to a long and healthy life.
