This question is best left for your veterinarian, he can give your dog tests to find out what the problem is.
If any part of the digestive system is bleeding , then your stool will have blood in it. The stool forms and passes through your intestines, bowels, etc , and if you are having issues with bleeding- then obviously the blood will pass down with the stool when it exits your rectum.
Blood in your stool is never normal. Depending on how it presents (on the paper, in the pan, mixed in with stool/on the surface, volume, colour) the causes can vary from an anal fissure (tear in the anus), haemmorhoids/piles or more sinister causes. Please get this examined by a physician.
Bowel movements should not be clear. However, there may be mucous i the stool. This could be clear or white and foamy. If the mucous is the only symptom, it is likely nothing to worry about.
WHY I HAVE BLOOD IN MY STOOL
It'd probably be best to see your general practitioner. Some of the common causes of black stool are iron supplements, beets, and blood in stool. Blood in stool could range from major to minor causes; some being benign and others being deadly.You should see your General Practitioner as soon as possible.

No, a herniated disc does not cause blood in the stool. See your health care provider, as blood in the stool always deserves a visit.
Negative blood in stool test means no blood was found in that particular smear from that particular stool sample. Good news.
A clear stool is usually of mucous-like consistency and may be slightly gelatinous. It could be due to an infection, bowel obstruction or irritable bowel syndrome.
