I guess, but I've seen a fair number of dogs at LBS, and they don't seem to respond when someone spins a bike on the stand.
This just doesn't make a lot of sense to me-- why is a high pitch sound randomly setting off a small subset of dogs? Also, pretty much any machine with high rpms would make sounds dogs hear that we don't. Dogs don't attack generators, for example.
