Q. Blood coming out when usin restroom
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. I would also add that since your dog is unneutered, blood in the urine could indicate problems with the prostate such as prostatitis, or prostatic abscessation. A good physical exam should include a rectal exam to evaluate the prostate.
A. You didn't indicate if the blood was seen during urination of defecation. Blood in the urine can indicate an infection, stones, or crystals, injury, even a growth or tumor in the urinary tract. Blood in the stool can indicate parasites, gastrointestinal upset, injury or ingestion of something caustic or irritating. I recommend getting your dog seen by your vet as soon as possible for an exam and labwork to determine why your dog is passing blood and get him started on treatment right away.

A. It could be blood from the urine or from the stools.
If it is from the urine - the most common reason would be a urinary infection or urinary stones. Both conditions require veterinary treatment, the first thing to do would be a urine analysis which is a simple cheap test.
If it is blood from the stools there could be many reasons - gastrointestinal infection, worms, foreign body, pancreatitis, IBD and more.
Either way the wisest thing to do would be to take him to the vet as blood from any orifice is not normal.
