Reward Special Cuts Dog Food For Her Brittany Spaniel Mix

I have a Brittany Spaniel Mix. His name is Roger and he is three years old. We feed him Reward Special Cuts Dog food. When he was a puppy we fed him the Wal-Mart brand puppy food. We bought it because he seemed to like it the best. Our vet has never recommended a certain dog food for him. We purchase his current dog food from Lowes Foods because it has the best price.
