Clyde is the biggest yapper in the world. HE LOVES TO TALK!! It took me a couple of months to teach him the command "quiet". Seriously, Clyde is so yappy if you let him be. I try to keep it to a minimum, though.
Dexter on the other hand is so quiet. He will make little huffing sounds. Like he is trying to talk to you. But only sometimes. He only barks if he thinks there is an intruder at the door or something.
I think it really depends on the dog
But I have noticed in my area the terriers like to talk.
