Toy breeds are less likely to bark?

Not my experience - I had 2 Cavaliers who were horrendously noisy - it was impossible to have a conversation with anyone one met on a walk, and if the car should have the temerity to stop e.g. at traffic lights, perhaps, they kicked up the most tremendous racket until it set off again. They also barked a lot in the house. I have noticed that many smaller dogs tend to be very noisy - good if you want a watch dog, but not so good if you have neighbours in close proximity.
