I want to know the answer to the following question:
Dogs have hunted with and done other things for people for a long time, but what is a more recent help to people they provide?
All the background I'm provided with is that "Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals.". Is that enough to answer the question?
Answer: yes
