Chipper left me a big surprise today when he laid several bright green poops. Although this could be a sign of intestinal problems, or eating too much green material, such as grass http://www.vetinfo.com/canine-medical-problems-dog-feces.html, I figured it was most likely from the bright green treats in his Christmas stocking. His body must not have liked it, since Cassie and Buffy ate the same stuff and were fine. Chipper was normal later in the day, so beware of the green Christmas treats!
