I have a dog and carry around a pack of small, thick, biodegradable and fragranced bags which I can use like a glove to pick up and bag any pooh. In our garden she is very clean and will only go on the gravelled flowerbeds. There is a trowel by the backdoor for collecting pooh and putting it into one of thos dog loos. I have trodden in a steaming pile one too many times to wish it on anyone else - hence the reason I clean up, besides, I'm not squeamish about stuff like that - I think that's one of the reasons people are reluctant to deal with pooh - especially when your dog has been "ill".
Horse owners are the worst - leaving foot high piles in the middle of country lanes - I own a low-slung convertible and there is no feeling like rounding a corner, hittong an unavaoidable pile and smearing fresh "horse apples" all over the front, bonnet and, on one occassion, flipping some into the car itself.
