Part of the problem is people with large dogs who need a lot of exercise and training only giving them the minimum, once a day walk and thinking that is sufficient. Why get a huge dog without time or land to allow it to exercise properly?
Some small breeds need a lot of exercise, too, notably terriers. I walked 3-4 miles a day when I had my lakelands, and when they were offlead they would cover probably twice the distance I did.
They were incredibly well behaved around horses and cattle, but had to be on lead among or adjacent to sheep or poultry. They were frightened of cyclists, one of them having been run over by a mountain bike that was being ridden illegally on a public footpath, so I kept them on lead on the short sections of bridle path that we used.
The only time one of them ever even pissed off a human wasn't anyone's fault. My bitch ran about a quarter of a mile alongside a jogger, who was really pissed off with her. However, the jogger kept calling her name, which happened to be the same as the jogger's fat lab who was waddling a long way behind, and unable to keep up with him. I called her too, but the wind was strong and blowing in the opposite direction, so I don't think she could hear me above him shouting.
I don't have any problem with reasonable restrictions, like leads in town centre parks (although it would deprive me of the occasional entertainment of an offlead dog running into Tesco, which is right next to a park and bordered by a riverside walk that runs through the park), and some beaches. (This is well managed at Camber beach: the beach is huge and half is dog-friendly, half dog-free, and ime the restrictions are observed).
I also think most dogs should be on lead in pubs, after once having a badly behaved (and huge!) springer knock a full pint of beer into my lap, and I have no problem with pubs that don't allow dogs. I just don't go to them.
