Dogs need (outdoor) space. As a dog owner you carry that responsibility.
Having a garden to (mostly) take care of this seems obvious. If not, when using public space instead, it seems strange to expect others (wildlife, kids,...) to take this for granted?
I remember one dog in particular, which was unleashed and running with its owner, who was on a bike. It would run ahead, staying on the correct part of the sidewalk, until it reached a crosswalk or corner, then stop and calmly wait for its owner to catch up and give permission to cross. I think one time (of the 3 crosswalks it was in view for) it got impatient and went back to its owner instead of waiting in place.
As a result, dogs are commonly (though not always) allowed in restaurants -- they stay quietly under the table -- and some other venues, which would be unthinkable in the US.
There's not too much of a point to this comment, just sharing perspective. I guess if anything it's that I wouldn't be so categorical about "if X, then Y, period".
Someone’s dog gets bitten every week or so and it’s a huge outrage.
Periodically a little dog goes into the big dog area and gets torn to shreds.
Now I have used same locations many times without issues. But it happens.
