IMHO I believe they do not give our mates the natural foods they need (similar to our diets..).
They say ....from natural ingredients .......... hmmm!!!! I wonder.
I will not subject my dog to the 'pigs ears' and like food The dried parts of animals (my choice) ..... some do not say where from and what from... I believe they are imported and you can guess possibly where from .....
However one must rely upon the more reliable types of dog/cat foods and hope that the ingredients, often not clearly described are OK.
Did read recently that --(not a pleasant topic) that if a dogs droppings, if left for awhile does not go a whitest colour then the food being fed may be lacking in some form of calcium..
Have a look at some of the foods -- Advertising ... packet soups in particular .. No (or Free) from MSG ... well my knowledge of MSG its a 621 yet a 631 635 is active in that soup and is very very similar to the chemical in MSG. Would love more time to go into more detail.....
