Hello, sorry to hear about Oscar. He could have an infection of his prepuce or penis. Additionally, he could have a UTI or urinary stones. Ideally, he should be examined by his veterinarian so that they can evaluate his penis, prepuce and look for evidence of stones or a UTI.

Look for straining to urinate, persistent blood in urine, and leaking urine. If you note any of these, then have Oscar evaluated sooner. Hope this helps and best of luck.

I'm glad to hear that Jack still seems comfortable and is active! I see that he has not been neutered, which makes it more likely that he may be experiencing prostatitis (inflammation of the prostate). Other possible causes of penile bleeding can be due to a urinary tract infection, bladder or urethral stones, crystals in the urine, among others. The slight decrease in his appetite may indicate a sign of discomfort. Many dogs are quite stoic and hide any pain they are experiencing quite well. At this point, Jack should be examined by a vet who will be able to perform a rectal exam to assess his prostate, as well as running a urinalysis to look for signs of infection or crystals. I hope that all goes well!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Seeing that Kane is not neutered and the symptoms you are describing, he could have a case of prostatitis or benign prostatic hyperplasia, in which treatment is neutering him. He could also have a urinary tract infection as well. I would recommend having him examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

My unneutered male dog is bleeding from his penis. What's the cause?

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.

Why is my dog's penis discolored and leaking discharge? Is it serious?

Dylan's prepuce is very swollen and appears infected and shows a lesion. This can happen if he licks it a lot, bacterial infection can cause that and also a type of venereal cancer called Canine transmissible venereal tumor or Sticker sarcoma. Here is information about Canine transmissible tumors: https://vcahospitals.com/know-your-pet/transmissible-venereal-tumor This is rather rare in neutered males, however it needs to be ruled out. I suggest you make and appointment with your vet to have your dog's external genitalia examined. Depending on the findings your vet may prescribe antibiotics or an ointment for treatment of the condition. In the meantime, if you have an e-collar, put it on Dylan to keep him from licking, as this will only make it worse.

My dog's penis is bleeding. How do I stop the excessive bleeding?

If the bleeding from Lucky's penis has gotten worse and/or not resolved at all you may need to bring him back to your vet for a recheck. The penis and prepuce are very vascular (meaning they have lots of blood vessels) and so can bleed easily. If the bleeding hasn't subsided at all there may be a larger vessel that is damaged that may need to be sutured closed to prevent any further bleeding. I would be sure to keep the cone on Lucky as well until you get everything figured out so he won't lick excessively down there and cause more irritation.

My dog's penis is bleeding and he's biting his paw. What should I do?

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!

My neutered dog's penis bleeds after toy activity. Should I worry?

It would not be typical to see bleeding from the penis following a neuter surgery. I would actually worry that Henry might have a wound on his penis or even a urethral prolapse. If you see any more blood I would recommend seeing an emergency veterinarian. Either of these problems could get worse if not treated promptly.

Why is my male dog bleeding watery blood from his penis after breeding?

This could be due to an inflammation which can have either a traumatic or an infective origin. Urinary tract inflammation could be present. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

My dog is bleeding from his penis. What can I do before the vet?

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. .
