I feed Lily Kibble, which I usually soak, for breakfast. Then the evening meal is Honest Kitchen which is a powdered food that you add water to re-hydrate it. She gets a Bully stick everyday to chew. And lots of toys. Plus she usually begs some small pieces of people food that I am eating. She loves buttered toast and any kind of muffins or biscuits.
For training which is based on rewards, I might use tiny pieces of chicken or beef jerky or cheese. Also use soaked kibbles as I can't over feed her. She is in good weight, lean and trim with lots of muscle from all the exercise.
