Why should I have to do that, why can't owners take responsibility for their stupid animals and just leave me alone? Your dog will bite me given half a chance and if I wanted to play with a ******* dog, I'd own a ******* dog - I don't own a ******* dog, and I don't play with your ******* dog!!! Virtually every run round the fields by me some stupid idiot dog owner allows their dog to chase after me and makes absolutely no attempt at getting the wretched things under control. I'm not interfering with you, why can't you lot (sweeping generalisation intended) just leave me alone!
Sorry, but I have absolutely no comprehension of why people keep dogs as pets.
