There's a website, somewhere, I forget where, that has a big, long explanation of "poo". LOL! It explains how to adjust your bone/meat/organ ratios according to "the state of the poo". I'm sure someone here knows the site I'm talking about but I'll see if I can find it. The general idea of that site was that all dogs are different and "know thy dog" is one's mantra.
If I remember right, it said that it can be a little confusing, in the beginning, because their bodies have to re-adjust and "clean up" from the previous diet - to get back to "normal". But that might have been another site. I was all OVER the cotton-pickin internet before I finally found this site! But the poo site is, I think, a good reference, and I want to find it again.
