I totally agree with you, Corzhens, and we usually feed regular cooked food to our dogs, and I know that many people are starting to do that now.
A few years back, so many dogs died from the tainted dog food which had an ingredient from China that was in one of the added vitamins put into dog foods, and after that , people stopped trusting the dog food manufacturers.
More and more products are being imported from China, and they do not have strict manufacturing rules like other countries have, so there seems to be a continuing trend of dog treats or some dog food that has to have a recall for one reason or another.
My belief is that dog food is not necessary if the dogs are getting a nutritional diet. Dog food itself has only been around for about the last 100 years, and before that , dogs and cats survived on what they scrounged and the table scraps that they were beinng fed, and they did just fine.
Most people lived in rural areas, or even in town, they grew a garden, and produced most of their own vegetables.
As industry advanced and more people moved into large cities to work, food manufacturing became a productive industry, and people bought their food rather than growing it themselves.
Naturally, there were leftovers and scraps; so that is when the food companies started making dog food from these leftovers from the food canning process.
Now, they have most people convinced that your dog or cat is not going to be healthy if they ar not fed commmercial dog food.
I think that if dogs and cats could survive without canned dog food for all of these thousands of years, then it can't be all that important for them to have it in their diet.
