The stool gets the normal brown color from bile, excreted from the liver into the small intestine. (for digestion). So if this bile does not come into the small intestine due to a liver problem (less / no production, e.g. in hepatitis) or an obstruction along its path, the stool colour turns white. (E.g. choleductolithiasis - gallstone). Some of the causes are rather serious, so a physician should be consulted promptly.

Speaking to my local vet, white stools from dogs (rarely seen these days) were due to eating bones. Remember when we used to go to local butchers instead of supermarkets and they used to give them out for free?

If this same problem is happening to anyone you know, I'd get them to seriously look into their diet - or visit the doctor ASAP.
