I sometimes rotate my outside bulldogs food but, I have an English Bulldog that lives inside. He gets boiled chicken with organ meat but, no cooked bones, vegi pasta blend with diced carrots, broccoli and green beans, collard greens. Sometimes blueberries, strawberries, organic peanut butter but, no nuts! Cheese as long as it's not a flavored variety such as Pepper Jack. Plain yogurt, cottage cheese, sometimes I use other meats such as beef or even deer meat and sometimes I'll dry it out to make a jerky for my dogs..
No potatoes cause they are hard to digest. Dogs love frozen green beans!...Throw them a chunk and they will gnaw away.

I know there are some things I am leaving out that we use but,...maybe I can think on it for a few.
Our English Bulldog is over 80 pounds and he's straight muscle, not fat...most people keep theirs fat. Ours like to run the yard and play without stopping every few secs to breath hard and fall flat on the ground, blown out.
I feed similar, 3 days a week to my outside bulldogs...the other days they eat River Run feed and I like it a lot for the price and the quality.
