And I don't mind owners picking up the dog poo in a little plastic bag. In an urban setting that's essential. In the countryside - fine. Yes, also good.
But what I can't stand is owners putting the biodegradable dog poo into a sealed non-eco-friendly plastic baggy, and leaving it lying there. Worst of all (and why the hell do they do this?) hang the little repulsive bag of decaying dog turds on a pretty tree?
'Hey, look at the fluffy willow buds... On second thoughts look away again.'
Leave it to decay, or take it away. But don't hang it up for me to inspect, because I don't wanna see it.
