Until fairly recently, dogs managed just fine on table scraps. (still do in many places). Commercial dog food began as a way to salvage some use out of what humans don't consider fit for the table. Put a fancy label on it, and sell it to people who had essentially been feeding the dog the same thing for free. Now the pet food companies have convinced people that you have to balance everything "just so" or it is detrimental to your dog's health. Funny how they survived for so long without such assistance! And the claim that dogs now live longer just doesn't wash. More and more ailments are showing up that used to be unheard of, and I certainly knew dogs when I was growing up that lived well into their teens on table scraps.
well said-processed foods do us all harm in time…..
