When we were growing up, our dog ate table scraps. I don’t think my folks every bought a can of dog food.
When “dog food” was first introduced to be sold in supermarket, it was pretty much made up with what we would refer to as “table scraps” with some quality by-products of meat. In fact, dog food was so much like people food that low-income people would eat it in a pinch and not get sick. Over the years, as competition increased, dog food makers looked for ways to make their product cheaper and we’ve been on a downhill slope ever since.
The difference is that people actually ate real food back then, not the processed stuff we eat today.
My Mom used to give the dogs a treat when her bacon grease was getting to nasty for frying chicken.
Gravy on old dried up bread.
They worshiped her.
