"Whatever happened to that white dog-poo from the seventies?"?
...What DID happen to that white dog poop?
In years now past when you didn't clean up the dog crap from your yard, in a couple months, it would be all dried up, and turn white. These days old dog crap turns a greasy blackish green. It's not even reddish-brown anymore! What the hell are they putting in (or not putting in) the dog food that they used to, (or used to not), that has inhibited the white dog poo phenomonon?
