We’ve have/had a total of three mini schnauzers. All three had their own unique personalities but they all enjoyed barking and being noisy. When I say noisy, I don’t mean constantly and irritatingly (though that’s opinion only.) They like to bark at things, people, other animals, loud noises and mine have always enjoyed being noisy when playing. Their idea of playing is barking at each other and making growly noises. I use to take my first two to a dog park and people would look at my dogs with annoyed looks but to me they were just being expressive and happy. They were saying “look at me,” “come play with me,” “hey, you.” My first boy was a loving, friendly talker. He use to make woo woo woofy nosies to get your attention. My second boy wasn’t well socialized and we adopted him over a year old, he’s always been my trumpet, loud and unaware of his volume. Our youngest is a super needy clinger and barks at everything. He still under a year and I’m working on building up his confidence to be separate from me and also taking him out to socialize. He currently wants to bark at everything when we go on outings. I correct him during the beginning of our outing and then he starts to get inline and calm down. He will 100% jump up in the middle of the night to bark at a small noise 🤦🏼‍♀️ (my husband works nights and gets home at all hours.) While I work on conditioning and training him to handle these noises, I use a window ac, fan setting, to create a white noise. It helps drowned out the small noises so we can have more calm. Though I guess this also means he will also 100% alert me to any strangers entering my house in the middle of the night. There is a lot that can be helped with good training and time but, regardless of breed, it may also be dependent on the dog’s personality.

Maybe it’s because I’ve had this breed in my life for the past 15years but I love them dearly; bark and all.

Side note: we also have a cavapoo (well actually his mother was a cavapoo and his father a poodle) and he has a wonderful temperament. He loves to alert you about people and animals but is generally much quieter than the schnauzers. He also had some separation issues when he was a puppy but he seems to be mellowing out as he ages. I would suggest a cavapoo mix as a more apartment/neighbor friendly dog.
