65. The following appeared in the promotional literature for Cerberus dog food. Obesity is a great problem among pet dogs, just as it is among their human owners. Obesity in humans is typically caused by consuming more calories than the body needs. For humans, a proper diet for losing weight is a reduced-calorie diet that is high in fiber and carbohydrates but low in fat. Therefore, the best way for dog owners to help their dogs lose weight in a healthy way is to restrict the dogs diet to Cerberus reduced-calorie dog food, which is high in fiber and carbohydrates but low in fat. Discuss how well reasoned... etc. In this argument the makers of Cerberus dog food recommend their reduced-calorie product as the best way for dog owners to help their obese dogs lose weight. Their reasoning in support of this recommendation is simple. To begin with, they point out that the best way to treat obesity in humans is by a reduced-calorie diet that is high in fiber and carbohydrates but low in fat. Second, they indicate that reduced-calorie Cerberus dog food is high in fiber and carbohydrates but low in fat. The conclusion drawn from this information is that Cerberus dog food is the best way to treat obesity in dogs. This argument is unconvincing for a couple of reasons. In the first place, the makers of Cerberus dog food assume that the cause of obesity in dogs is the same as the cause in humans. Given the vast differences between the exercise patterns and basic diets of humans and dogs, this assumption is highly dubious. Lacking evidence to support this claim, the argument is unacceptable. |
