My Mason is only around 4 months so i'm not sure how loud his bark will be when he gets older, but he does bark. He is not very loud, and he is definitely not a yappy dog, but when we play with him or if he wants my attention, he will bark. It is usually just one little yap or two, not a barking fit like my peekapoo will do. We laugh because when we wag our fingers at him and scold him for tearing something up or doing his business on the floor, he back-talks us! I mean he really lets us know what he thinks about it! So we never really end up correcting him because we just end up laughing at him. I know that I am probably setting myself up for problems later on down the road, but we will just have to deal with them then. He's just too cute right now.
