That is one possibility.
The color of your stool varies for a number of reasons. Some foods (such as black licorice) have a strong black color that will persist even into the stool. Your digestion does not always work in exactly the same way, either, depending upon the level of activity of your intestinal bacteria, for example. A black stool can also indicate some degree of bleeding in the gastrointestinal tract, since the blood turns black (or very dark brown) as it clots. So there is a possibility of an ulcer or other such problem. However, you would probably be experiencing pain, as well as seeing a black stool, if you had an ulcer. I would not jump to any conclusions after a single day of black stool.
It may be from something you have eaten (like black liquorice). Another possibility is that you are bleeding somewhere in the lower IG tract, caused by many various things. However, you should go to a doctor and get it checked out as it may be something serious.
It means there is bleeding in upper gastrointestinal tract such as bleeding from dudenal ulcer. Medical Terminology for Black stools is malena.
No, blood in a dogs stool can mean any number of things from mild to serious. Take your dog to the vet along with a stool sample if possible.

Nope, the vagina does not connect with the rectum at all. Blood in the stool can mean many things from not so serious to very serious. See your doctor to find out what's bleeding up in your intestines.
Large clots would mean that the bleeding had already occurred. If there is considerable distance to the outside of the body, such as from an ulcer or intestinal bleeding, then you would have just the clots by the time it makes it out of the body.
the dark red spots in panties are the periods (the monthly bleeding from a women's womb)
No, there is no reason to suspect an STD based on blood in the feces. Rather, than an STD one would suspect a bowel disorder or hemorrhoids. The color of the blood in your stool indicates from where in the bowl the problem is. Black tarry blood suggests digestion and therefore the blood is coming from very high up along the intestinal tract (ulcer). Bright red blood suggests a bleed close to the rectum (hemorrhoids, fissure or simply a scrape from a hard stool). If the bleeding continues to the next bowel movement, seek advice from a medical professional.
Depends if it is a fresh blood or a digested one and its severity. Fresh ones are usally due to hemorrhoids but some do happen because of the cancers close to the anus. Anything higher in the intestine will look black, due to its digestion. A severe ulcer bleeding might turn the whole stool black. Anytime there's a blood in stool, that's require medical examination. The sooner it is, the easier to solve any potential problems early on.
Dark blood in a cat's stool means that he has a bleed somewhere. You should have him checked by your Vet to find out what is causing the blood.
