DOG WALKERS

Hi my friendly dog walkers if you are going to walk your dog in any neighborhood,or park what is the proper etiquette when your dog poops anywhere.I know the dog walkers I know carry bags with them to pick up there dogs mess .I do not like the dogs pooping in my yard ,but I know as a owner of 2 dogs that I can't rush them home to do there stuff,so I clean up there mess and very greatful to the walkers out there that do,this its only right.i'm posting this because it was brought to my attention that a friend dog poop on someone lawn the owner clean up the mess.And that wasn't good enough for the resident in the home.
