The things you learn off Twitter
Ben Goldacre linked to a blog post where he said that white dog shit is merely brown dog shit that the maggots and slugs have eaten all the wet bits of, leaving behind only the calcium/roughage.

The proponderance of white dog shit up until the 1980s just meant that dog owners were such dirty bastards that they left the turds of their precious little snookums to lie rotting for months until they turned white.

That and the vast quantities of Winalot that no self-respecting dog owner would be seen without back then.
