I am not sure why some people worry so much about the consistency, frequency, colour, amount and what they perceive as "quality" of their dog's poop. I am also not sure when this started to be an issue to which we must pay daily attention.
One would expect it will be somewhat different all the time, depending on what your dog ate, how much he drank, if he ate some grass, how much he exercised and so on. IMO there is no one set standard for a perfect dog poop! I don't want them to have the same triple coiler every time! When my dogs run hooked up to a sled their poop is completely different than when they are laying at home all day. All of my dogs eat the same thing for the most part and they all have different poop.
Slime or mucus-like substance on your dog's poop is normal. It is there to lubricate and help get rid of potential parasites. If you go read up on it, you will get the same extreme nonsense overload that unfortunately, many internet articles provide. Sort of on the same lines as GSP dogs are evil, run away, don't listen and even being aggressive. All those myths I gave you, are the ones I like so much proving to be wrong over and over.
Some blood in your dog's poop is OK too. Esp on the surface and esp if they exercised a lot. It just happens from time to time.
If your dog has a severe diarrhea when it's mostly water with blood and running down his back legs, that is a different story. You probably should visit your veterinarian and get a bit of antibiotics for their intestines and in in some cases you might need IV fluids. But that will not happen to most of you and the ones that it will happen to, trust me you will know! Even then stay chill. It likely will be Giardia or Parvovirus (parvo is almost not possible for puppies from us) and both have survival rate of 95% if treated.
So stop worrying about dog poop and have fun :)
PS: some dogs fart much more then others and there is nothing you can do about it, they are just fine! ;)
Below is an example of a dog infected with Parvovirus and of an example of what it looks like when you should worry.
