[Science and the world of tomorrow] An extract to cure Alzheimer’s is developed but to get an ounce of it require the destruction of 10,000 dogs, would you ever use it?

Scientist discover that an enzyme in the brains of dogs had the ability to prevent and even cure Alzheimer’s, but it took three 2 oz. doses of an enzyme derived from the brains of dogs, and each ounce took the destruction of 10,000 dogs, would you use it or advocate it’s use? What if a family member had Alzheimer’s, would that change how you feeling about using it? If the demand for it grew to the point mills were established where dogs were bred just to supply the extract like cattle are now bred for food, how would you feel?
