I had never given a lot of thought to my dogs food, I assumed a big name brand and claims written on the bag meant it was good for them, until the brand I was buying got pulled from the shelves in the pet stores. Then I did some research. I chose Purina One Smartblend Lamb & Rice, and after the first bag was gone, I couldn't believe the difference! My male dog, Dexter, had always had digestive problems and suffered bouts of diarrhea, and suddenly, they were gone! No "adjusting" to new food, they both just ate it up and had no issues. Their coats were so shiny and soft, and even though they are young and high energy, their was a noticeable "pep" in their step. I will never feed them anything else, and as they get older I will look to more Purina foods to keep them healthy! Thank you!
