Ar yes. The walk. Anybody been for a stroll lately? Land mines are rare these days, to right, but there is always one who does not have a pooh bag. Or just cant be 'arsed'. Anybody notice the fairly constant smell of Dog piss, esp. on a nice warm sunny day? Lovely. Still, as long as your lawns nice and clean...
....yes, I notice many other things despoiling the world too: beer/beverage cans scattered at the roadside, burger/chip wrappers, the smell of urine/vomit in multi-storey car parks, disgracefully-drunken 'yoofs' ruining many a`town`s summer evenings and general-litter seemingly everywhere: but, as it is with dog-fouling; it is a minority spoiling it for the rest of us. 
Your right in what you say Debs of course, but not the point i was making. That being, EVERY dog owner will take their dog for a walk rather than have it urinate in their own garden. Quite happy to inflict it on every passer by rather than have it outside their back door, but yet seemingly the first to complane when they get similar unfair treatment on their own property. Nobody wants crap on their lawn, and nobody wants a public place to be used as a public toilet. In that respect Dog owners are simply not a minority, they are ALL at it re. urinating.
Dont get me wrong, its a fact of life, thats what dogs do. I am not complaining about it in that sense, it does not bother me. I just NOTICE it, if you know what i mean. But having noticed it, i just think, how can you complane about crap on YOUR lawn one minute, and then take a dog out for a walk and let it piss in everybody elses public space the next? Wtf?
Anyway,i would be interested to know how waspy gets on with those water jet things if he gets them?
We may get some for grumpy chops over the road.
Or maybe not, she will probably moan about it making her gravel wet.(the gravel she layed, at great expense, over the grass to stop cats crapping on her lawn, the cats love it, they can bury it )
Cheers
