Why is my male dog's penis bleeding and irritated after an erection?

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.

As long as his penis went back to normal and you are not seeing him drip any more blood you don't need to do anything. I would not get worried about one incident. That being said, once they start doing this, especially at his age, it can become a life-long problem so I suggest you have him neutered. Then you would not have to worry about prostate issues, persistent erections, etc. The blood dripped out because it pooled in the urethra because of the erection or he injured his os penis (bone inside the penis). It is definitely not an infection so don't worry about that. Just keep monitoring him and consider neutering.

Pip may be causing trauma to his penis or prepuce by being too aggressive about humping. To avoid future trauma do not allow him to have the bear. He may need an examination by a veterinarian to ensure he has not caused excessive damage to himself or to ensure he does not need pain medication or antibiotics. At minimum please make sure he can urinate normally and does not lick around his prepuce or penis. If he is having any issues or the bleeding persists he will need to see a veterinarian.

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.

It's a little difficult to tell for sure, but I wonder if Charlie had a persistent penile frenulum. It is a band of tissue that runs along the underside of the penis and attaches near the tip of the penis. That will cause the penis to curve. Normally we recommend surgically cutting the frenulum. I have not had one rupture on its own. They do not typically reattach after surgically cutting them. I would recommend having your veterinarian examine it to make sure that it was a persistent penile frenulum and see if anything else needs to be done about it. In the meantime, I would recommend trying to keep Charlie from licking at it and prevent any humping. If you are unable to stop the bleeding, then he may need to be examined tonight. Good luck!

Hello. Dog's penises should NOT be dripping blood at any time. Also, if his penis is enlarged and red and stuck out this is an emergency right away. Dripping blood can be a concern with a urinary tract infection, polyps, urethral obstruction (stones, etc). prostatic disease (cysts, infection, etc). These all require a vet visit, so I would get him to the vet as soon as possible, especially if he seems painful or cannot pee (postures to pee but nothing comes out). Good luck with Dingo.

Poor guy. Scruffy has likely caused some trauma to his penis, leading to inflammation and this can lead to the penis getting stuck outside the sheath, strangulation of the penis, and even infection. I am unsure exactly how the penis currently looks, but the treatment is dependent on its current condition. If it is stuck outside the sheath then the vet needs to treat this by doing a sugar pack on the penis, or similar method to reduce the inflammation enough to replace the penis back inside the sheath. Also KY jelly is often used to facilitate this. If infection is present then oral antibiotics along with a copious sterile flush (i.e. chlorhexidine solution 3% diluted) of the penis is needed. Pet friendly NSAIDS (i.e. Meloxicam, Rimadyl) are also often need to reduce inflammation and provide comfort.
