Marking in the House: Is the use of bellybands making things worse?

This article from Dog Watch discusses the issue of marking in the house by two neutered Italian Greyhounds. The problem has increased in the last six to eight months, and the dogs have ruined curtains, rugs, and a bedspread. The owners have tried using bellybands on the dogs, but they still urinate in them. The article suggests re-housetraining the dogs by using umbilical cord training and monitoring their elimination patterns. It also recommends removing water dishes at night and feeding them meals to regulate their bladder. [Extracted from the article]
