For some reason I can't shake this so coming to AIBU.
I took my dog for a gentle walk this afternoon. He is recovering from an injury so was on a long-lead, to prevent him running but also so that I could communicate to other people that he doesn't want to say hi to their dogs today (I reel some lead in for this - it's not an annoying flexilead, it is a highly visible bright lead that you can't miss at all). This is what I did with other dogs I saw, whose owners respected this and didn't let their dogs approach.
We were in an empty field so he had a bit of lead with freedom to move around and sniff but could be shortened. Part of it got tangled in a branch that had been blown over so I was untangling it. As I did, an off-lead dog appeared out of nowhere and charged towards my dog. He was a few metres away from me as I was reeling his line in and it was stuck on a branch. I called to the owner "he is recovering from injury so is on-lead and won't want to say hello to yours". The man smiled and did nothing. After five seconds or so of looking super uncomfortable with a dog sniffing his face (which most dogs don't like anyway let alone when in pain), my dog asked the other dog to move. It didn't, so he chased it away (out of character behaviour because he is injured). He made a bit of noise whilst doing so but didn't make any contact - he wouldn't. By chase away, I mean he ran the couple of metres of his lead he had back to me and the dog happened to run alongside him.
The guy then shouts "FOR F* SAKE". I asked why he let his dog run up to on-lead dogs (there was another on-lead dog with me and a friend, that one was fine but is nervous so isn't let off), and he said "this is a woodland, your dog shouldn't do that". I told him that I have as much entitlement to walk my dog as he does his, and mine was on-lead, his shouldn't have approached or he should have recalled it.
He made a big scene of checking his dog over (fine to do - I witnessed the whole thing happen and my dog didn't touch his but did make some noise, as dogs do when communicating) and went on without saying anything. I did note that he put his dog on a lead afterwards. For some reason I can't stop thinking about it - I think because it's a normal walking spot for me and I don't want people to get the wrong idea about my dog. This was out of character for him due to recovering from an injury, and because his lead was around a big branch it was tight. My dog is generally comfortable with small dogs (which this was), doesn't like GSDs so we just avoid them.
I think I'm just a bit more flustered as the man got aggressive, usually people acknowledge that the other dog was on a lead.
YABU - you're in the wrong and should have apologised
YANBU - the man should have recalled his dog when you said yours was injured and on-lead, and not blamed you
I should add I work with dogs professionally so in terms of reading the incident etc I know that my dog did nothing but make a bit of noise to clear the other dog off. Feeling extra touchy over the last few days...aunt flo is due.
