When you buy the equipment maintenance.

 During my thirty years of veterinary practice I have often been upset by the poor condition I see some of my canine patients in due to inferior quality diets that the owner honestly believes to be adequate. In good faith the dog owner assumes that since the dog food label proclaims "complete and balanced", "premium", "high protein", and so on, that their dog will automatically do just great if that's all it is fed. Because of ambiguous or deceptive labeling of the dog food, the owner unknowingly will feed an inadequate diet. And it may be decades before the FDA requires more strict guidelines for dog food manufacturers to follow so that misleading, ambiguous, and sometimes phony labeling practices no longer confuse or trick the purchaser.
