Needa, I think I feel vulnerable because our fields are used as a cut through to get to a motorway bridge, so lots of people walk through the middle of them, not just dog walkers. I'm generally a big wuss though, so it's probably just me being pathetic.
I have the same rule of thumb re on-off lead. I just wish other dog walkers did. Actually, the only place people don't seem to get it is in our local park and that's exacerbated by the fact that Lurcherboy appears to think he owns the place and Pip associates it with out-of control off-lead dogs. We never have a problem when we walk elsewhere at weekends.
Interesting morning here. Dh was going to see dd's nativity and was home for an hour beforehand, so we took the dogs together. Met a bull-lurcher whose owner clearly doesn't get 'the on-off-lead rule'. Both mine were on lead, as we'd just arrived in the park and not only did she approach, she blooming flung a tennis ball right into the middle of us, cue Lurcherboy going loopy trying to get to it and starting to bark as he really wanted to play and Pip getting worried as a result and starting to bark. Owner then did a big semi circle to avoid us, while not recalling her dog, which kept running around us, stopping a few feet away and staring at my two. I would have let them off, but I couldn't judge this particular dog's body language and I knew Lurcherboy would be a pita over the tennis ball. Owner then marched off into the distance, yelling 'your ball's behind the tree you daft dog' without looking back. 
Fortunately the rest of the walk was great. The park emptied and we had half an hour for our guys to chase each other round and round. Only downside was that Pip managed to do a full somersault and side-slide through the muddiest part of the field and was a real mess afterwards. I had to bring him home, spot wash and rub him down, as we had puppy class in an hour!
and ... my neighbours have been out since before this morning's school run - so, when they were still out when we got back from dog training, I popped an exhausted Pip in his crate, gave both dogs kongs and Mum and I went to the local garden centre for coffee! We were out for 53 minutes and Pip yelled for about the last 8.
I think he may have stopped before I got back, but as I snuck in and didn't go in to switch the recorder off straight away it's hard to tell.
Need to try going for an hour and see if he does settle after the initial realisation I've gone once he finishes his kong. Fingers crossed my neighbours are going to make a habit of being out for whole days at a time - or are going to go away for the holidays, which would be even better.
It's not much, but it's a start.
Have taken to leaving him in his crate after walks and sneaking upstairs, then reading my book on the landing to see if he's quiet. Did 15 minutes today - going for 20 tomorrow!
Dog training went really well. Did outdoor recalls but with a longline for reassurance and he couldn't wait to get back to me. Showed me up actually, as I'd just been telling the trainer how he seems to have developed typical adolescent intermittent deafness on recall over the past couple of weeks.
He also had a proper play with a couple of the puppies and met a gorgeous teeny spaniel/golden retriever puppy - so all in all, not a bad day, but we're both exhausted now. 
Oh - and have discovered dd's nativity is only half an hour, so might be able to leave him in the house, rather than putting him the car after all.
