- you dont see it any more!Answer..The disappearence of white dog poo is down to what dogs eat these days.White shit is the calcium left behind as the water evaporates, and the 'organic' components of the crap are consumed (in various ways) leaving the inorganic stuff behind.Historically, before BSE came along, butchers used to dish out bones for dogs to munch on.But nowadays dogs don't eat as much bone as they used to, including bone meal. This all got the lid shoved on it due to the BSE crisis. Also, tighter regulation on dogs crapping on pavements means that turds don't hang around for years in public places like they used to, giving them less opportunity to dry out and turn white.Now who says you don't learn anything on these forums....
