Personally, I would never feed mine Cesar's or anything with by-products. Of course, that is my personal choice and not necessarily that of others.
I do not have picky eaters so that's a plus on my side. However, I believe that any food is better than no food. If your furbaby will only eat this.....then why not?
My toy poodle attempted to be picky....I never gave in to her desires.....she snapped out of it and realized she doesn't run her meals
I do spoil them every now and then and home-cook some of their favorite foods........makes their day
