I don't know much about dog poo, i just got my first dog 2 months and a half ago but still, I think my dog's poop has been through every single phase described above, except green poo and the really foul smell and he's fine... He eats normally, and when I gave him raw beef he pooped a little blood out called the doctor he said its fine. Whenever we have a strange stool we dont necessarily have a life threatning disease do we? Unless the puppy has a constant problem with his stool and his behaviour changes there's no need to worry. Once my pup pooped wood.... he was on the balcony one day and i thought he was going to do his thing because i couldnt take him outside, and when i checked on him after 3 minutes he somehow knocked a small tree off the balcony ledge and started munching on it. the next day he pooped some wood but was completely fine. Another time, I went to the bathroom to wash and left him alone in the living room. Bad idea. There was a pillow on the couch, he ripped it up in 15 minutes and ate a bunch of feathers. The next day he pooped them out and had a runny stool for the rest of the day. He was still fine. I'm just saying....You can spot a problem with your dog instinctively, don't need a chart, It will worry you more when he will leave a stool that looks like one written in there.
