In particular, when the writer suggests that adopting dogs will reduce the ongoing medical costs of heart disease patients, we should be skeptical. Even if the study cited proves there is a salubrious effect in owning a dog—which it most certainly does not—then we still don\'t know if this effect is curative or merely preventative. In other words, just because owning a dog might help prevent heart disease, it doesn\'t mean that it will cure heart disease once one already has developed it.
Furthermore, who is to say that heart disease patients will be “encouraged” to participate in the “adopt-a-dog” program? While recovering from a serious disease, taking responsibility for an animal may be the last thing on a patient\'s mind. We cannot assume that sufficient numbers of patients will participate in the program for it to be a success, and thus we cannot assume that the ongoing costs of treatment will be reduced.
Short of seeing some evidence of the successful promotion of similar programs, we must not assume that the “adopt-a-dog” program will appeal to the broader community, especially if it does not succeed in lowering medical costs among the heart disease patients. Those not already suffering from a disease are often inclined, after all, to ignore the benefits of treatments that do not apply to them. Few people, for instance, obtain flu shots until it is too late, though they are widely available.
