Dog food ingredients
I see many people who feel some ingredients used in dog food are abhorant. Fillers---parts of animals like intestines, for instance. Corn is another.
Granted, corn is a bit unnatural, but is digestable and useable by dogs. And in the wild, a dog will not only eat the entire dead prey animal(including waste system contents), but will eat grass and even wood, if hungry enough.
Inert ingredients are more of a concern to me---stuff used for bulk that cannot be digested---several cheap brands have too much of that.
I have used Pedigree for many years---feeding dogs that lived to be 15 and even 20 years(Chihuahua mix)---and had no digestive problems traceable to the dry food.
I now have a whippet mix who cannot eat any canned(out of three brands/types) and can do just fine on Pedigree dry.
I just don't get it.
