As Bornyo said science diets are the way to go and offer graduated stages of nutrients as your pooch grows. My uncle used to have two poodles and he made his own dogfood in a crock pot from cheap goat cuts, onions, carrots and vitamins the vet had recommended to him. He swore by it and never had to clean up messy shit again. Brewer's yeast will help prevent fleas, too.
