That's too bad because I was thinking of bringing someone over there who has a large dog. The dog is very quiet - but about 100lbs. What I have found about dogs and noise is that size really doesn't matter. It's more breed related than size related. In fact smaller dogs are more likely to be disruptive barkers. For example, I have two Siberian Huskies. They are on the large size, but one thing about them is that they don't bark. The reason I have 2? Dogs are social (particularly huskies that are bred to work together) a dog with a companion is less likely to be disruptive when the owner is away from home. The big Bernise owned by my buyers hardly makes a sound. If she does, there is a good reason and you would want her making noise. In general large breeds (particularly giant breeds) are calmer - and therefore less noisy.
Just an observation about those thinking of rules for condos. One of the problems is that those who make the rules don't know that much about dogs and their behavior. Another issue - 2 dogs are often easier to handle noise wise than one. Dogs are social, if they have a companion, they are less likely to be disruptive when their owner is away.
