I take up 50cm of width of a path. If there is 1m spare that's abundant space to pass safely. Most paths can accommodate that if all users are aware of their surroundings, pick a side (I tend to keep left) and stick to it. If the path is too narrow for your personal space issues with too many other types of user, pick your routes accordingly.
I'll keep as wide a berth from a dog as I can. I've had far too many encounters with "friendly dogs" poorly trained nuisences When I'm running, I'm processing a lot of things, both my own spatial awareness; my path ahead, other path users, my speed. I'm also probably tired (in which case you'll hear me coming). I'm trying to analyse the people around me, are they paying attention, dogs are another whole set of layers to add in. Is it on a lead? Will the lead get longer? Is it going to approach me?
Generally people move in before I've processed that I would need to slow down and pant an "excuse me" Often saying excuse me is worse than just passing because they startle, pause and scatter, and they weren't aware of their surroundings anyway.
It's not just dog owners who take up a lot of space; couples that can't detatch and tuck in, friends walking 2 abreast across the middle of the path using up most of the width. I might be on a shared cycle route and listening out behind me (I use bone conducting earphones so I can still hear), but dog owners are abundant and naturally want to use the same type of spaces that I want to. I've been jumped on in random fields having seen no one in miles because the owners thought there would be no one else there and let their guard down.
It's harder trying to work out how a human/ dog combination will behave than just humans. I don't want to be responsible for a dog, therefore I don't have one. It's exhausting that 10% of owners lack adequate control and observation, and I'm having to work out what random animals of differing breeds and temperment may do when their clueless owners abdicate responsibility.
I do move aside as much as is reasonable, but I'm not going to constantly shout, slow, stop, or risk myself in mud or bushes when there is adequate space to pass freely.
I choose my routes where I can likely run freely according to my objectives (avoid lots of roads, narrow pavements, crowded multi-use park) and other people can also take responsibility for where they go if they have extra preferences.
