I think we would probably felt more compassion to them and understand more their needs. For instance a vet would not have to give drugs to dog to calm it. We would also be less of speciests. If an elephant in circus told the audience how he is beaten with a whip to make all these fancy tricks people would probably no longer come to circus. It would be truely a magnificent share of experience as they have senses other than ours. They have that unique ability to be in a certain moment. Unfortunately we have little clue how animals are experiencing their reality.
