Were the lessons learned about both human and canine diabetes worth the sacrifice of those dogs? Is additional more refined animal experimentation (e.g. mice, rats, dogs or cats) justifiable today? Does your answer depend upon the species? What factors do you consider most highly in reaching your conclusions (e.g. comparative physiology, ethics, specific training of researcher, importance of animal studies before human studies, study of companion animals like dogs, current alternatives to animal research, Food and Drug Administration legal requirements for animal experiments before drug development in clinical patients, human or other species, etc.)?
