Other species recognize the different meanings in dogs’ barks, as well. I lived for several years next to a wonderful habitat for ducks. I fed the ducks cracked corn, and my Doberman pinscher would call them. The ducks only came to his “The human has food” bark. They didn’t respond to the “I hate bicycles” bark or the “Stranger’s at the door” bark. I also would be extremely surprised if sheep don’t recognize the different barks of a sheep dog.
