Our last Bouvier Sampson was an accomplished talker. He was able to vocalize when he wanted to eat, when he wanted to go outside and when he wanted to go for a walk. I can't tell you the sounds that he made but they were each distinctively different. There would be times when he and I would have conversations, I can't tell you what we said but he was usually satisfied when we finished. Our current Bouv's, Jewel and Clifford are not as prolific talkers as Sampson was but Jewel, being his niece has some of his characteristics. Clifford just give a slight growl when someone new comes by. Jewel on the other hand will wake me to feed her (07:00 and I'm retired). She'll also let me know verbally when its time to go for a walk.
I wish Clifford could talk, but with him being being a rescue I'm just happy that he's here.
