How loud is it at the lowest setting - hopefully not obnoxious? And is the volume adjustable on the fly?

At the lowest setting it makes no noise at all. That's because the adjustment valve, which is located on the horn itself and not the tank, is essentially infinitely adjustable. It's just a rotating valve that allows less and less air through until it lets no air through the line at all. But you need to turn it almost completely off for any affect. And yes, it is certainly adjustable on the fly.Having said that, I don't know why you'd ever want this on anything less than the loudest setting. If you're trying to alert a car that you're there more volume is always a plus.

does this product scare dogs away?

Never used mine with dogs but it sure does make the squirrels jumped up in the air.

How do I repair the Schraeder valve? Will not let me refill. Two different bike shops cannot figure it either - volume is set wide open. Thsnk You.

You could try a valve core remover, you take the tool and twist the valve core (The thing in the tube that keeps the air in), until it comes off. Then you could reinsert a replacement one from another Schrader tube you might have, or buy another valve core.

what type of sound does it make?

It sounds *exactly* like the high tone on a two-tone European emergency vehicle, but *LOUDER*
