To bike riders, this is kind of like the Jaws music.... you know something bad is coming.





EDIT: After reading the rest of your post.... I'm disappointed. I'm glad you didn't have an incident, but I was expecting some action.

To contribute something... my observation is that most people control their dogs on the MUP pretty well around here. I occasionally come across an unleashed dog and I'll ring my bell far enough off to give the owner fair warning. As long as they see me I figure they know to take appropriate action. A lot of the time that means they do nothing differently; the dogs are well-healed and don't chase bikes. Sometimes they reel in the leash or grab the dog so I can pass. So far I haven't had a negative dog incident on the MUP. For context, it runs through a green space along the river, and frankly it is a pretty good area to let a dog run (assuming they're properly socialized). I try to bear in mind that MUP means multi-use. As long as we all get along I don't mind if they let the dog run.
