history: I got annoyed the other day when a woman was walking her dog. It had an extendable lead and was blocking the pavement I find people with extendable dog leads annoying.
current: What about it is annoying? Isnt it better for the dog?
next: It probably is better for the dog. But the owners aren't always responsible. Where I live they use them on the sidewalk and block off the whole area for other people walking.
