Dogs helped in studies that developed modern anesthesia, used to stop pain during surgery. Without anesthesia, surgery would be a rare, painful process.
Research Process

Research Basics:
What is biomedical research? Looking at a breakdown of the terms according to the Webster’s Dictionary, we find “bio" meaning “life or living organism,” “medical” meaning “healing; pertaining to the science, study, or practice of medicine, or the art of healing diseases,” and “research” meaning “careful, patient, systematic, diligent inquiry or examination in some field of knowledge, undertaken to establish facts or principles.” In simplified terms, we can understand from these definitions that biomedical research is the search for ways to heal living organisms such as humans and other animals.
Types of Research:
Experimental design profoundly influences the outcome of a research study and is, therefore, extremely important. The first step in designing an experiment is identifying and clearly defining the question or problem to be studied. The objectives of the research study must be realistic, in other words, they must be achievable. The next step is to choose the research model that is best suited for the experiment. The model may be a culture of animal or bacterial cells, or a whole animal of a particular type.
