How is her weight, Winston? If her weight is good, she has good energy and tolerates her food well, I'm not sure I'd change anything. Labbies are
notorious food hounds...no matter how much you give her, she's going to want more.
What about the ear infection? Is that an ongoing problem that might be due to food intolerance? If so, I might want to experiment with other foods, then, but otherwise, "if it ain't broke, don't fix it" might apply.
If you want her to eat a little slower, maybe put a Kong or a piece of large-link chain (too big to be swallowed
) in her bowl when you feed her. That should slow her down a bit. But as long as she's been keeping it down (not throwing it up from eating too fast), that's probably unnecessary, too.
