Granmarderby10 you think that all those park dog walkers - and there are a lot of them, are thick and that their dogs don’t ever poop while out, even ones that visit the park at least twice a day? You are mistaken. Not entirely sure what you're trying to say here; but yes, based on what I've witnessed in my front garden and my local park, and some comments on this thread, I do think some dog owners are thick.
Yes, I've heard and seen dog waste bins. They're the foul smelling, overflowing receptacles that have plastic bags full of dog shit piled on top of them when the council has cut back it's services and no longer empties them. They have several overspill areas such as bushes, fence posts, even people's garden walls.
I actually love dogs Granmarderby10; it's their lazy, dirty and entitled owners that I don't like. The dogs are only as good as the human on the other end of their lead.
