Dogs are people too
Human-to-dog communication will continue to improve, so dogs may pick up on more human traits. Dogs could understand more complex thoughts and emotions. It would help to be able to communicate clearly to your dog that the uncomfortable ear medicine will make them feel better. Better communication would be useful for service dogs to communicate with their owner or with strangers when they need help.
Dogs are already good at reading and responding to humans, but improved communication between humans and dogs could lead to even greater levels of understanding and cooperation. Before we know it, Canine Centered Design will be commonplace.
