I'm not sure what to do with that... He never gets runs, even when I changed his food. Pep went to his training class on Sat morning (no breakfast - but got snacks to make him perform better), then to the groomers and I picked him up after 2. We went home and he pooped dark green. Then it's been runny or at least loose. Is there anything I can give him? He eats good quality food - Nutro holistic and Wellness mix and organic treats (did I overdo with treats while training.. the groomer might have as well
)... Help please
