Why shouldn't dogs have personal space?
Should dogs tolerate everything and anything that happens to them - dogs on a lead are trapped just as much as a dog cornered in a tight space, dogs DO have personal space and often can have personal space issues (reactivity) - it is something I work with a lot! It is THAT common I would say about 70% of my job is dealing with dogs who cannot cope with strangers in their personal space.
Now its reasonable and a vital part of behavioural modification to make sure the owner takes sensible steps to avoid people GETTING in that personal space - yes... but that means things like, turning around, creating more distance, getting off paths and out of the way.
It does not mean that its reasonable for total stranger to RUN up to an unknown dog and get inside a 6ft 'bubble' though - particularly for someone to run up from BEHIND that dog in sneaky silent running shoes.
There is only so much environmental management anyone can achieve, so given that seeing dogs outside in public is a normal thing and a perfectly reasonable thing it would make sense if folk knew not to run up behind them or head on at them, and to give them a good six foot berth when passing if the owner either can't see you coming OR makes it clear they'd like a bit of space.
Its hardly going to ruin your day, inconvenience you enormously, but it might keep you safe and it might mean someone elses day ISNT ruined (becuase yeah, its soul destroying when you have spent HOURS working with a dog and you are making progress and then someone hurtles up behind you, startles the dog who reacts and then you are back to square one again!)
You might think 'well I don't have a dog so why do I need to think about these things' but .. I don't drive a car, but knowing the basic rules of the road helps me not cause accidents or get flattened.
We all have a responsibility to be courteous and think about other people as well as our own needs - or we might as well just have total fucking anarchy!
