In making a quality dog food, the manufacturer usually builds in a “safety factor” over and above the known daily allowances. In this way, tolerances are made for the individual dog with unusual requirements and for the alteration of the complete and balanced diet by owners who like to add “extras” or table scraps. Such additions should never exceed 10 to 15 percent of the complete diet.
The great advantage of feeding commercial dog food is that it involves very little time or work; the dog enjoys his food because of the variety, and you can be sure that he’s getting proper nourishment. It also eliminates the digestive upsets common in dogs that are switched from one kind of food to another, as when only home cooked meals or table leftovers are fed. Another danger in feeding table scraps is that, over a time, some dogs become spoiled and prefer the “extras” to a proper diet.
