Why does my 9-month-old dog have diarrhea and blood on his penis?

I see that your dog is not neutered - I'm not sure how old he is, but in middle-aged or older unneutered males it is common to see blood dripping from the penis as a symptom of an [enlarged prostate](https://www.petcoach.co/dog/condition/prostate-enlargement/). That is normally the first thing that I would check out in a dog with this problem. Other possible causes include an injury or tumor on the penis or the penile sheath, a bladder or prostate infection, bladder stones, kidney disease, or even a systemic bleeding disorder. I would recommend taking him to a vet for an exam - they will probably want to collect a urine sample for testing, check his prostate during a rectal exam, and examine his penis closely outside the sheath to look for any problems. From there, x-rays and ultrasound can be used to look at the prostate, if needed. If the problem is due to prostatic enlargement, this can normally be improved with [neutering](https://www.petcoach.co/article/benefits-of-neutering-castrating-male-dogs-puppies/) and does not typically cause any long-term problems.

His penis looks inflamed, possibly infected, you will need to take him to the vet to get it checked, he will need to wear an e-collar in order to prevent from him to continue licking his penis and getting it worse, he will also need an antibiotic course.

He could have an infection and need an antibiotic. Keep the area clean, dry, and prevent him from licking the area until you can take him to the vet. If the bleeding seems excessive or he becomes lethargic than he should be seen immediately to rule out a clotting problem. .

Blood from the penis can be a result of a urinarh tract infection, prostate issue, bladder stones, or trauma. I recommend having Nemo examined by a veterinarian and having a urine sample checked to see if an infection is present. He may need X-rays to rule out a bladder stone. It would be best to have him examined as soon as possible as these issues can progress quickly. He may need a prescription medication like an antibiotic to treat the underlying issue. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Nemo is feeling better soon!

Bleeding from the penis indicates a serious problem. In an unneutered dog, it could be a prostate infection, enlargement, or tumor. Some other possibilities include a urinary tract infection, bladder stones, or a systemic bleeding problem (coagulopathy). I suspect that his paw biting is unrelated and may be due to allergies or a hot spot, but he should definitely be seen by a veterinarian to determine the cause of both issues and come up with a good treatment plan. Best of luck!

Blood in the urine in male dogs is usually a sign of a urinary infection or a prostate disease, you will need to take him to the vet today in order to get it checked and treated, he will probably need an antibiotic course.

Thank you for submitting your question. Diarrhea and the bloody urine are likely due to separate causes. Diarrhea can be the result of an intestinal infection, dietary indiscretion (eating something that upset her gastrointestinal tract), inflammation or even stress. Bloody urine is typically due to a bladder infection, bladder stones, a primary bleeding disorder or in rare cancers bladder cancer. She will need to see her veterinarian for urine and fecal testing as she will likely require medication to treat her issues. I hope this information helps!
