My male dog is bleeding from his penis after mating, is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Bernese Mountain Dog | Male | unneutered | 2 years and 6 months old | 105 lbs

My Bernese male mounted our female Bernese who is in heat. We are mating them. We believe he entered but did not seem to tie up. If he did it wasn’t long. He is now bleeding droplets from his penis. It stops but starts back up when active. Just happened last night. Should he be seen or will he be ok if it stops on it’s own. This is his first time. He’s 3 and she’s 2 1/2. She is fine.

Thanks for using Petco Pet Education Center, formerly Petcoach! The safest thing would be to have him evaluated by a veterinarian so that the area can be looked at more closely. They can make sure this is not something due to trauma or perhaps an infection before continuing to mate. Have a great day!

    It could be that Tony sustained trauma to his penis during the mating, and that's causing the bleeding. I would apply gently pressure to his penile area to try to stop the bleeding. If that doesn't stop the bleeding, or his penis continues to bleed on and off, then I would have him seen by a vet.

My male dog has watery blood from penus hours after sex with female?? What could it be?
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.

Thanks for using Boop by Petco! This would in fact warrant a recheck with your veterinarian. They may choose to proceed with diagnostics at this point such as a prostatic wash or perhaps just trying a different antibiotic. Hopefully this is nothing serious. Good luck!

Teddy got over excited which resulted in an erection however I noticed blood on on of him legs. After a closer look I discovered the blood was coming from his penis. Teddy is not my dog so I am unsure if he is intact or not. What could cause this ble
Hello and thank you for reaching out to Boop by Petco. Blood from the penis can be due to prostatitis, which is inflammation/infection of the prostate. This is often treated with antibiotics (commonly Baytril or enrofloxacin), and non-steroidal anti-inflammatory medication. Other causes of blood from the penis can be a severe urinary tract infection, causing the urine to be blood-tinged. I recommend having Teddy evaluated by a veterinarian who should perform a rectal exam to palpate Teddy's prostate. Your vet can also perform a urinalysis to look for evidence of infection. I hope this is helpful!

Milo has been trying to hump my females head, she has been chewing on his Penis wen he does this. After she got him to stop he went to pee and bright red blood came out b4 the urine , urine was normal colour.straight after he had diarrhoea. He has no
Hello and welcome to Boop by Petco. It sounds like the female might have caused some damage. A vet visit isn't a bad idea to make sure there isn't any damage that requires surgical fixing. Otherwise, monitor his peeing very carefully, as strictures can form that cause a blockage. If there is ANY trouble peeing, or continued blood, then have it checked by a vet. Best of luck with Milo!

Everytime my dog gets excited he expels blood/mucad out of his private part. Just started today he's a boy
I'm wondering if he's neutered or not. If he's not neutered, then this could simply be sperm coming out of his penis. If it's bloody, then there may be a problem with his prostate. To be safe, have him checked out by a vet. Best of luck.

My dog has blood in his pee but we also have another dog in heat and he is going crazy humping and licking could the blood be from him licking and the irritation of the humping and licking or is it something else more serious?
It could be from an infection, irritation/trauma, or possibly bladder stones. Your vet can test a urine sample for infection and then prescribe medications to help treat the problem. You could also consider having him neutered to help decrease the problem in the future.

Hello I NOTICED THIS MORNING MY DOG WAS BLEEDING A SMALL AMOUNT OF BLOOD FROM HIS PENIS HIS DOES NOT SEEM IN ANY PAIN HIS TEMPURMENT IS NORMAL ALONG WITH HIS EATING REGARDS DAVID CAVALIER
Hi there and thanks for posting on Boop by Petco! Blood coming from the penis can be an indication of a variety of medical conditions including a urinary tract infection, prostatic infection/inflammation, or skin infection if the blood is coming from the prepuce (skin around the penis) among other causes. I would recommend Henry see his veterinarian soon for an evaluation. Henry's veterinarian may want to take a urine sample to check for a urinary tract infection first before ordering other tests. I hope this helps!

I have a 6 month old poodle pup he was getting randy and humping my other pup and his penis come out and was bent around like a u shape and then it ripped and went straight but it's bleeding like crazy!!! I sprayed it with purple spray(animal) and it
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! I hope that was helpful. Thanks for using Boop by Petco.

We picked up a male stray he extremely skinny and I've noticed that he's been dripping blood from his penis . What could he have? The camera quality is bad but it is definitely blood I've also noticed it on my floors
It is hard to see from the picture, but if it is blood coming from the penis I would be concerned about a urinary tract infection and/or bladder stones. Since you just found him it would be a good idea to take him to the vet to get checked out anyways, and you can bring a samppe of his urine so they can check it for infection. If he does have a bladder infection it can be treated with antibiotics. If he has bladder stones, often times these need to be removed by surgery.
