If not, and it was say, a MUP in a populated area, you are just as likely to get taken out by a five year old learning to ride their bike on a MUP who turns left when they shouldn't, or a jogger with their ear buds in, or entitled walkers who think they should take over the whole width of the MUP in order to walk side by side. I have already said that dogs in populated areas should be on leash though, in case that point was missed. That would be the responsible thing. On mountain bike trails however you are far more likely to get taken out by novice riders who don't know trail etiquette and stop around blind corners, enter trails without checking etc... Not by well behaved trail dogs.

But more directly to the point: the person had their dog on a leash, apparently in compliance with the law. They were doing what was legally required. This is a pretty good example where personal responsibility works better than law. If she had been personally responsible that probably wouldn't have happened. In adult dogs that behavior likely wasn't for the first time and she would have though of that potentiality. Instead, she put the dogs on leash as was legally required and gave no more thought to her responsibility.

Now you have to make another law.
