Last summer I was walking along a narrow footpath in the village when a man and his 2 children came along behind me on their bikes, he rung his bell to alert me to the fact that he was there. They had their (big) dog with them which was off lead running just in front of them. I called my dog to heel and stood aside as far as I could to let them past. Their dog clocked mine and bounded towards us, I could tell from it’s body language it was dominant/ and or aggressive. It flew at my dog and knocked her to the floor and then kept jumping on her and everytime she escaped from under her would pin her again, growling. I kept trying to grab it off my dog or grab my dog but it was just a tangle of legs/ arms etc. The owner in the meantime wasn’t at all bothered, my dog was cornered because of the footpath being so narrow and so she couldn’t run away so in the end I said to him ‘can you please get your dog as mine is going to go for it in a minute.’ He got off his bike, came over and managed to haul his dog off mine.
He lives in the village, just down the road from me. Since that day I haven’t seen him around the footpath with it again but have seen him most weeks biking around the village with it running alongside on the lead. I half wondered whether this was because it had annoyed or attacked another dog as it’s quite obvious it’s got no recall when off lead when it spots another dog. I’ve walked past him with me on the path and him on the road with his dog since and the bloody thing lunges, growling nearly pulling him off his bike once we’re parallel with it. Again, he doesn’t seem to register this at all and says in a cutesy voice to it as we’re almost parallel ‘who’s this for you to say hello to’ and grins inanely as this thing growls and hauls him around on his bike with me praying he doesn’t let go of it.
Cut to today, was quietly wandering, annoyingly along the same narrow bit of footpath as last summer and I hear a bike sound it’s bell behind me. It was him and his dog, so I called my dog to heel and stepped off to the side as much as I could. I thought it was on the lead, but then as they got closer, realised it wasn’t. It started thundering towards us and my heart was in my mouth he shouted pathetically to it ‘be nice now, who do we have here for you to say hello to?’ No is your dog okay with others, is it okay if mine says hello etc. I knew there was no point in asking him to put it on a lead as it was about 20 yards away at this point and fixed on my dog and I knew it had no recall so knew he had no hope (and so did he!) i had put mine back on the lead but quickly let her off so she would be able to run if needed (though hard as it’s so narrow) it launched itself straight on her knocking her to the floor and then growled and went for her neck and my dog started screaming so I ran over and clapped my hands and screamed loudly ‘Get away from my dog.’ My dog then managed to break free and ran behind my legs, with me stood between my dog and his dog. He went ‘it’s fine, calm down it’s just noise.’ I literally couldn’t even open my mouth to reply I was that angry. He grabbed it and cycled off. No apology, no acknowledgement of what had just happened.
I’m 20 weeks pregnant and am a raging ball of hormones atm so maybe I overreacted but ultimately, his dog had no recall when it’s off lead if it sees another dog. It is a BIG dog and thunders towards you, hackles raised, growling with him feebly calling it to no avail. He doesn’t ever say ‘can my dog say hello to your dog?’ ‘Is your dog friendly?’ Just calls out ‘who is this for you to say hello to?’ 
My husband wants to go and knock on the door and ask him to keep it on a lead if he can’t control it off lead but I’m not sure he should as I think it’ll end in an argument and it’s a small village. I’m just upset as I’m not going to be able to relax on walks now knowing this thing could appear at any moment and my dog certainly isn’t a fan of it now after she’s been jumped on/ pinned to the ground twice by the bloody thing.
