What is crub?

Question

When i was in a bus i saw a sign said "Curb your dog before walking." Tell me what it means.

Answer 1

It's a polite way of saying "have your dog go before you leave your own yard, so he doesn't do it in someone else's yard."

Answer 2

Curb means pick up after he goes poo..

Answer 3

Curb your dog actually means have them go on the edge of the sidewalk, so that after you pick up all you can, you don't leave a nasty smudge or pool of urine that other people step on and carry around.  Dogs have a tendency to just stop and drop when they've got to go, so having them do their thing before taking off gets them in the mindset that they're expected to relieve themselves before they walk, rather than during the walk.  You're also more likely to address the scat if it's in front of your residence.
