Mine are all pretty quiet. Teddy and Sophie bark when the doorbell rings. Sophie also barks at Teddy when i am going to walk her as if to tell Teddy back off it's her turn
London doesn't bark, except when she wants me to put her on the bed and it's sorta like a whine, if i ignore her she gets louder and makes sure i hear her LOL But when im out with them, if they're in the carriers no they don't bark. They are used to it.
