Your dog will go through many physical changes throughout his lifetime. As he grows from a puppy into an adult dog, and then again as he gets a little older and matures into a senior. Along with these life stage changes come varying nutritional requirements, which are effected by his lifestyle as well. Requirements also differ enormously from mini to large breed dogs. The morphological and physiological differences between them are fundamental.
The Purina ONE product range is specially tailored to meet these specific needs. So you can be sure Purina ONE will help see him through from puppy to maturity in the best of health.
