Though it is not illegal to allow your dog to poop on someone else’s property, it is illegal if the excrement is not removed immediately. Be a good neighbor and bear in mind that some neighbors put a lot of work into maintaining their landscaping. It is best to avoid any conflict by steering your canine to the tree lawn, which is public right of way. Denver Ordinances (Sec. 8-73.) requires that all dog excrement is removed immediately from any property that is not your own, public or private!
