I have only ever fed dry dog food, but my 3-year-old lab is starting to get a little weird about eating. She frequently looks at the food then looks at me several times, then will dig in. My in-laws have had a couple of labs over the years that refused to eat unless they added some real meat or other tasty stuff. But that was often in their later years when they seemed to be more pampered/stubborn/finicky. Funny creatures sometimes. Good luck!
