I have used Purina Pro Plan for the last 5 yrs. since starting Days End Retrievers and have fed it to over 90 dogs. prior, I fed Pro Plan for over 10 yrs. to 16 personal dogs. several of my dogs lived to over 14 yrs. of age.
Over the past 15 yrs. I've tried several different so called quality foods. I have always come back to Purina. Why? Top quality for the price. well balanced at 30/20 for the client retrievers that I train. I haven't had any other food that gave the dogs any better coat any more energy or more mussel mass and maintain as small of stool. Its also for all stages of life pup-adult.Pro Plan has changed its name to Sport but is still in 37.5 lb. bag.
