I feel sorry for people with young children in the park where people let their dogs off the lead and then stand around chatting to each other oblivious of what their precious pooch is getting up to. I agree with Frenchpolisher, the city with its limited open spaces is no place for a dog, or even a cat as gardens get fouled and birds are killed. People could keep other types of pet in a cage and that way they are totally responsible for everything it gets up to.
