So what do you think of this scenario then?
Went for a run last night down a local bridlepath and spotted a couple ahead coming towards me with some dogs. The man starts shouting something and I assume he's calling the dogs back, so think not much of it and carry on. 2 of their dogs come running up to me, super friendly and I can see they are youngsters so I just stop to fuss them and carry on.
When I reach the people, the man is holding a larger dog on a lead and says "Those 2 are OK they are puppies, it's this one you need to watch for as he is aggressive". I say "Ooh dear" give them a wide berth and the man says "Well I did tell you to stop" so I reply "Oh I thought you were talking to the dogs." and then run on.
Thinking about this afterwards, it's clear then that these people had a dog they know is aggressive off the lead and unmuzzled on a public bridleway and seem to think it's OK though if they shout at other path users. Unbelievable! Funny though too. Don't some people take the biscuit?!!
