So true!
Wonderfully written and truth in every word. I have a thought on white dog poo, this is my own theory.

Years ago dogs ate table scraps, basically anything we didn't want to eat, and that usually meant very little meat. Meat has a high iron content which turns your poo dark. So lack of meat would turn a dog's poo white. The reason why we don't see white dog poo any more is because we always feed them food with a high meat content. That's my theory and I'm sticking to it like dog poo to a shoe!

Not so.
The liver breaks down haemoglobin from the blood, producing bilirubin, which is excreted in bile from the liver. This is what gives mammals' poo its characteristic brown colour, rather than the diet itself, although as we know the colour can vary.

Incidentally, this important physiological process is referred to in 'The Silence Of The Lambs', where an imaginary character is named Billy Rubin.
