I think you can get carried away getting too worried about poo, sure.. (but hey, it IS only something thats going to happen to people who know on a daily basis what their dog produces and what to expect, better than those who have no clue at all!)..
Like people, theres a scale - the extreme ends are to be avoided, the middle of the range is ok.
I know that my dogs 'normal' is small and very firm, usually one or two pieces not loads of little bits, no mucous, mid brown and turns white if left more than 36 hours.
If they produce something a bit harder I'll adjust the diet, if they produce something softer or the wrong colour, again I'll look at whats going IN.
Currently, OH forgot to order the meat so they have had a week on Fishmongers which is Pets at Homes own brand fish and spud cereal free food - firm, kickable poos, bit dark in colour but then the food is VERY dark in colour too. Wouldn't feed them on it long term (they get fed up of it after a week anyway) but short term it seems fine.
But - theres a LOT of folk out there that think their dog producing huge, voluminous, shapeless BRIGHT ORANGE turds is normal and ok...
The colour of a turd (I cant believe I am writing this) is quite significant, obviously discount this if you know you are feeding something highly coloured... orange means in short, the food is moving through the gut too fast and isn't being properly digested. This is also signified by the large and loose appearance of it and the fact that it appears to take MONTHS to break down (you see the same turds on the pavement if you walk the same routes often enough!)
Not really a coincidence that the dogs that I know produce poo like this, eat low quality primarily grain based foods, which are not very digestible, and have to be fed it in large quantity (I was horrified how much Wagg Complete a friends dog needs to eat compared to the equivalent I'd feed of Taste of the Wild - same sized and aged dog!) to provide the necessary energy/nutrition.
