We do not expect a female dog to bleed from her private area if she has been spayed. Also known as an ovariohysterectomy, spaying is a process whereby the reproductive organs of the dog are removed. This means the dog cannot go into their heat cycle, something which can be accompanied by a certain amount of blood spotting. If we see our dog has blood on her privates and they have been spayed, we need to consider the time since the procedure has been carried out. Bleeding soon after spaying surgery will likely be a complication of the surgery. If the bleeding occurs long after they have healed, it is likely due to a problem unrelated to the surgery itself

Although bleeding after dog sterilization is relatively rare, a dog that has recently been spayed/castrated can experience bloody discharge or bruising. For this reason, at AnimalWised we will be discussing why my spayed female dog is bleeding form her private area.

What is spaying in dogs?

Before explaining whether it is normal for a spayed feamel dog to bleed from her private area, we recommend understanding what exactly dog spaying means. In order to do this, we need to understand the difference between neutering of male dog and female dogs[1].

Although there are several techniques for sterilizing a dog, we will refer to the two most common types:

  • Male dog neutering: castration of a male dog is a simpler intervention than that of a female. This is because a male dog’s genitals are found outside the body. A veterinarian will make an incision in the scrotum, through which they extract the testicles. This incision is usually closed again with a couple of visible or non-visible stitches, which are later removed.
  • Female dog neutering: spaying a female dog is done through an incision in the abdomen. A veterinarian will extract the ovaries and uterus, normally arranged in the form of a Y shape. The different layers are sutured both internally externally. The incision can also be closed with staples. This surgery is known as an ovariohysterectomy and is carried out if we don't want the dog to have puppies.

In the cases of both castration and spaying the wound needs to be protected. After-care of spaying and castration both require keeping the wound covered, making sure that the dog does not lick, scratch or bite the wound. To avoid this, your veterinarian can give provide your dog with an E-collar. For more, take a look at our article on how to stop a dog scratching a wound.

In addition, it is important to keep your dog’s wound clean while it heals. A professional will be able to administer the appropriate cleaning medication and disinfectant.

Complications after spaying surgery

Complications after surgical neutering are uncommon. While bleeding from the private area in a spayed female dog is a cause for concern, there are various complications which can arise in these rare circumstances. This is why it is important to monitor the animal closely after the procedure. However, there are certain behaviors and symptoms which might be relatively normal after sterilization.

  • Dog crying after anesthesia: when the dog eventually comes round from the anesthesia, it is common for some to cry or whimper a little. They are likely disorientated by the anesthesia and the stitches will cause further discomfort. Another issue is that they may be hungry, although we shouldn't feed them too much too soon.

  • Dog heavy panting after surgery: another sign of discomfort is that the dog is panting heavily after being spayed or neutered. This is also due to the often traumatic experience of the surgery and why veterinarians will usually prescribe pain medication to manage these symptoms.

  • Dog disorientated after surgery: since the dog has been given certain drugs, when they regain consciousness it is understandable they will be a little confused.

  • Dog drooling after anesthesia: drooling after being given anesthetic is a natural reaction to loss of muscles control.

The above aide effects of sterilization surgery are considered normal up to several hours after the surgery. However, if they continue into the next day, you should call the veterinary clinic to discuss the symptoms as they may be a sign of complications.

Is it normal for a female dog to bleed after spaying?

When removing a dog’s uterus and ovaries, an incision is always made. It is normal that at times this incision will result in light bleeding during the intervention or after surgery. This bleeding is normally controlled by the veterinarian performing the surgery.

During surgery, the dog may be given certain anesthetic drugs such as propofol[3]. This drug lowers the dog's blood pressure, which will raise again once they gain consciousness. The increased blood pressure can cause some seepage from the wound, but it should not be excessive.

During a dog’s postoperative period, due to the incision and invasive techniques used, it is normal that the surrounding area will be have a red or purple hue. This is otherwise known as a hematoma, i.e. blood that remains under the skin which causes a bruise-like effect. If the bruising is seen all over the abdomen, this is not considered normal and may signal internal bleeding.

At times, this wound can also appear inflamed. In this case, female dog bleeding a little after spaying is normal. This is often largely due to a fallen stitch, that hasn’t yet closed the wound. In this case, the bleeding will be minimal, remitting in seconds.

Do spayed dogs get periods?

Spayed dogs do not experience heat cycles or menstruation. We have already explained that spaying involves the removal of the uterus and often the ovaries eliminating the reproductive organs responsible for the heat cycle and the associated hormonal changes in female dogs. After spaying, the dog no longer goes into heat. This means there is no shedding of the uterine lining, which is what occurs during menstruation in some mammals.

Even sexually intact dogs will not get periods. Dogs do not experience menstruation in the same way that humans do. Instead of a menstrual cycle, female dogs go through a reproductive cycle known as the estrous cycle which is the proper term for the heat cycle. During the heat cycle, hormonal changes occur and the dog becomes receptive to mating.

The estrous cycle typically occurs twice a year, although the frequency can vary among individual dogs and breeds. During this time, a female dog may exhibit certain behavioral changes, such as increased friendliness, restlessness and a swollen vulva. There may also be a bloody discharge, which is a normal part of the cycle.

Brown discharge from a spayed female dog

Brown discharge from a spayed female dog can have various causes. It's important to note that any abnormal discharge from a spayed dog should be evaluated by a veterinarian. Some possible reasons for brown discharge in a spayed female dog include:

  • Residual blood: in the immediate postoperative period, some dogs may have residual blood discharge which can appear brown.

  • Infection: whether at the incision site or in the reproductive tract, infections can lead to discolored discharge.

  • Vaginitis: inflammation of the vagina (vaginitis) can cause changes in vaginal discharge color.

  • Urinary tract infection (UTI): infections in the urinary tract can sometimes cause changes in vaginal discharge. Learn more about the types of urinary tract infections in dogs with our related guide.

  • Foreign body or suture reaction: occasionally, reactions to sutures or the presence of a foreign body can lead to discharge.

  • Hormonal changes: even in spayed dogs, hormonal imbalances might cause changes in discharge.

Since brown discharge can be a sign of various underlying issues, a veterinary examination is necessary to determine the underlying cause.

Should I be worried if my spayed female dog is bleeding from her private area?

While minimal bleeding after a dog’s surgery is normal, excessive bleeding is a cause for concern. If your dog is bleeding after being spayed, the amount of blood present needs to be assessed along with other symptoms. Immediate intervention is required in the following two circumstances:

  • When bleeding comes from a specific external point, such as stitches or staples, it might be because they have been detached. In this case, treatment will involve the veterinarian re-suturing the entire incision. If there is excessive bleeding with an evident open wound, it needs to be attended to by a professional immediately. If not, organ prolapse from the incision is possible. An open wound also heightens the risk of infection.
  • Bleeding can also be internal. If your female dog is bleeding a lot after being spayed, other symptoms may be noticed. These signs include pale mucous membranes, apathy or a drop in body temperature. Such symptoms also require immediate veterinary attention, as they can result in shock.

If the bruises caused by sterilization are not extensive, go away and are not painful for your animal, veterinary consultation is not required. However, if your dog feels pain and is experiencing excessive bleeding after being spayed, we recommend visiting your veterinarian as soon as possible. When the abdomen is bruised and inflamed all over, this is particularly worrying.

If your dog is bleeding abnormally after neutering or spaying, be sure to consult a specialist.

Dog bleeding after spay treatment

If you see an excessive amount of bloody discharge after a female dog is spayed, then we need to see a veterinarian. They will be able to asses the dog's health and perform an examination of the incision site. Only then will you be able to treat the cause of bleeding after spaying.

Under no circumstances should you try to treat the the dog yourself. If surgery is required, it will need to be carried out in a sterile environment by a professional. They will have the right instruments, medications and expertise to best ensure the dog's safety.

While it is normal for our dog to be in a certain amount of pain, we should not give any pain medication unless specified by the veterinary specialist. Giving a dog human medications is not safe and increasing dosage may cause serious side effects.

If your veterinarian has decided further treatment is necessary, they may need to go back into surgery. This could be to re-suture the incision, suture the cause of internal bleeding or treat any other internal complications. If there is an infection antibiotics will be used either solely or in conjunction with surgery. Treatment of the bleeding will depend on its specific cause.

Other complications may not be related to the sterilization itself. If you see bumps on your dog's vulva, it is possibly a skin condition which can lead to bleeding. Our article on reasons your dog has bumps on her private area might help determine the cause, although you will need to see a veterinarian for diagnosis.

Ovarian remnant syndrome

Although uncommon, post-operative bleeding in spayed female dogs can manifests as she is experiencing heat. It is not normal for a female dog to bleed after being spayed. A female dog that has been spayed should no longer experience their heat cycle.

If a spayed female dog bleeds from her private area, there is a chance that your dog is suffering from ovarian remnant syndrome. This condition means that not all of her ovarian tissue was removed during her canine ovariohysterectomy surgery. This left-over tissue could be releasing a small amount of hormones, thereby tricking your dog's body into thinking it is in heat[3]. Another possibility is that if your dog was spayed while in heat or just before she was about to go into heat. In these cases, she might bleed from her vulva.

Any other female dog bleeding from vulva symptoms can be an indication of pathology. A dog bleeding from her vagina may indicate problems such as urinary infections. The blood you may be seeing could be coming from her urinary tract rather than her spay incision. In addition, spayed dogs are more prone to suffering from UTIs, specifically just after being spayed.

However, if you believe your dog is suffering from a urinary tract infection, we recommend consulting your veterinarian. Untreated urinary infections in dogs may lead to other more severe health problems, such as kidney infections in dogs.

My pup was in heat and I didnt know it when she was spayed. Well she is bleeding off and on since her surgery 7 days ago, Its just like a discharge off and on. Should I be concerned or is this just the ending of her fertility cycle. thank you.

My dog died after being spayed at the vet. We were told by her owners that she was 3 years old, but the vet said she was more than likely 5 or older. I took her to the vet to get spayed a few days after we got her. She seemed very healthy. They did her surgery around 11 in the morning. I called them around noon and they said she had just finished the surgery. I went and picked her up around 5. She was still very groggy, but the vet said that it was probably due to the anesthetic. They said her temp was low and her gums were kind of pale, but they also said it was more than likely the anesthetic. I brought her home and monitored her. She continued to stay cold, so I put a blanket on her. Then around 9 she came out and went to the bathroom. I really thought she was doing better. At 1:30 in the morning, I heard her get up and she collapsed on the ground. Her breathing was getting bad and she was super cold. I called the vet and they met me up there. She died on the way there. They did a necropsy on her and said that her stitches were all in place correctly, but she had bled to death. They said that it was more than likely a bleeding disorder that they didn't catch during surgery. So basically she bled out over the course of 8 hours. They also told me when they did the necropsy her blood was still just pooled in her abdomen and had not coagulated at all and this was at least 6-8 hours after death. Please help me understand what happened as I am having a very difficult time with this. It just does not make sense at all. Is there anything that the vet or I could have done to save her? Did they mess up? I am just so confused by all of this.

Hi Brittany,

First of all, we are so sorry for your loss, it is tragic. We cannot say or comment what happened with your dog. It is an individual circumstance and it would not be responsible to do so. However, we can say that the complications for spaying surgery are minimal, but it will never have a 100% success rate, especially because of hidden complications even very experienced veterinarians may not be able to see.

Annette Fino
My 2 yr old female dog was spayed as a pup. She has some vaginal bleeding. Can it be something other than UTI?
Administrador AnimalWised
Hi Anette,

It is possible, but we cannot say we are afraid. if you are at all unsure, you will have to take them to the veterinarian to be sure. As the article states, there are different possibilities which could explain bleeding.
Kay Martin
Is this normal? My dog was just neutered and this has appeared. He has also been draging his butt more frequently.
My dog has surgery last month for Pyometra , a couple days ago she started to bleed is that normal the vet said it’s prob all the stuff left over but it’s been a month so I don’t know what to do ,
Administrador AnimalWised
Hi Christine,

It will depend whether it is bleeding or spotting, where the blood is coming from, is it a problem with the incision healing or is it internal bleeding? There are many factors and variables which only a veterinarian can diagnose, I am afraid we cannot be of any help as it would be irresponsible to simply guess what might be the problem. If the veterinarian is confident, then they should know what they are doing. If you don't trust your veterinarian, we suggest seeking a second opinion.
Had to take my female back to the vet 4 days after being spayed because she had some discharge. They said everything looked good minus some swelling which was causing the discharge. They gave her some more medication for pain/inflammation and started her on an antibiotic even though she doesn't have an infection. The discharge had stopped for most of the day but picked back up last night and now is much worse. The sound isn't open anywhere that I can tell but the discharge is coming from the same spot. Since it's Sunday trying to decide if I should take her to the emergency vet or wait until tomorrow to go back to our vet
Our dog was spayed five days ago. Since then she has been peeing blood. At the beginning of the urine stream it's mostly clear, towards the end its bright red. I called the vet who made it sound like it wasn't a big deal and may just be some bruising or a UTI. She was already on amoxicillin but the vet added Baytril so now she's on two antibiotics. She also said to stop the pain medicine. Does this sound right? I worry that there's something more serious going on although she acts basically ok otherwise. She's not her normal peppy self but she's not lethargic or anything either.

Hi Laura
If you´re worried we recommend keeping in touch with your veterinarian and checking up regularly. If medication and treatment has already been prescribed, we suggest giving it time to work. If you don’t notice a change, let your veterinarian know. For more, you can take a look at these following articles:


HI. Is your dog better? Did the bleeding stop? My pup is experiencing the same.
Santie Dyer
My dog was sterilized on Friday since bringing her home my mail dogs have gone totally mad, what would be the reason for this.
Administrador AnimalWised
Hi Santie,

We cannot diagnose behavior in the comments, but it sounds like it will likely have something to do with the sterilization. They may have found it traumatic and are acting accordingly. Reassuring his safety and providing a lot of love will go a long way. He should settle down, but if not, you can ask the vet for some specific help.
