What is Estrus Symptoms After Spaying?

Female dogs go through several stages during their reproductive cycle. Symptoms of estrus usually occur about twice a year with an infertile resting period in between. The spaying operation, called an ovariohysterectomy, includes complete removal of the uterus and ovaries, the tissues that release hormones and create the estrus cycle. After spaying, your dog’s reproductive cycle should cease and she should not exhibit any more estrus symptoms. Sometimes however, over the course of the operation, part of the ovarian tissue is overlooked and left behind. This part may continue to release hormones which activate fertility and your dog may appear to be in heat even though she is no longer able to get pregnant. This is called ovarian remnant syndrome (ORS.) This condition is usually reversible with surgery. The longer the tissue is left, the higher the risk of complications.

Sometimes female dogs will continue to exhibit symptoms of being in heat after they have been spayed. This usually happens because part of the ovarian tissue was left behind during the operation. Veterinarians define this condition as ovarian remnant syndrome.

Symptoms of Estrus Symptoms After Spaying in Dogs

Your dog may develop symptoms shortly after the operation, especially if she was already in heat. Symptoms may be cyclical and resemble a normal period of estrus. Try to see a veterinarian during the time your dog is exhibiting symptoms:

  • Swelling of the vulva
  • Increased licking of the vulva
  • Vaginal bleeding
  • Behavioral changes
  • Lifting the tail (flagging)
  • Standing to be mounted

Types

 

There are four periods to a female dog’s reproductive cycle. The first two constitute the fertile period of being in heat:

  • Proestrus – the pre-mating period which lasts for 7-10 days, symptoms include swollen vulva and vaginal bleeding
  • Estrus – the mating period which lasts up to 10 days, symptoms include flagging and attempted mating
  • Diestrus – the period when your dog is either pregnant or resting between mating cycles, it can last from 10 to 140 days
  • Anestrus – the non-fertile dormant period which lasts until the beginning of the next proestrus.

The time between cycles as well as the length of the mating period can vary based on the breed and the individual dog.

Causes of Estrus Symptoms After Spaying in Dogs

  • Failure to remove all of one or both ovaries during surgery
  • Accidental dropping of ovarian tissue into the abdominal cavity during surgery
  • Ectopic ovarian tissue – ovarian tissue which develops in another part of the body (rare)

Surgical error or poor technique is the cause of most problems, although occasionally a dog may have a genetic abnormality and generate ectopic tissue outside the ovaries.

Diagnosis of Estrus Symptoms After Spaying in Dogs

The veterinarian will be able to diagnose a swollen vulva and signs of bleeding on a physical examination. Anesthetic may be required to make a more thorough examination and insert a catheter to check that the blood is not coming from the urethra. Vaginoscopy will allow the veterinarian to examine the inside of the vagina to check for injuries or other problems. Biopsies of the vagina will often be also taken to evaluate estrogen levels. Bloodwork can often show elevated levels of estrogen and progesterone as well.

Ultrasound of the abdomen will usually reveal the presence of abnormal tissue. Some tissue can be difficult to see, so, if your dog has strong symptoms of estrus, the vet may decide to perform exploratory surgery even if the mass is not visible. Biopsies will be taken and any removed tissue will be evaluated for malignancy.

Treatment of Estrus Symptoms After Spaying in Dogs

Treatment of Estrus Symptoms after Spaying in Dogs

Surgery is the recommended treatment for ORS. The surgery is called an exploratory laparotomy. This is typically a low risk surgery, similar to the ovariohysterectomy that is performed during spaying, although the remaining tissue may be more difficult to locate. Your dog will likely be released the next day. You will need to check the incision for signs of infection and the veterinarian will schedule a two week follow-up appointment.

Some dogs with additional medical issues may not be good candidates for surgery. If this is the case, the veterinarian may still be able to treat your dog’s symptoms with medications that prevent her from going on heat, including megestrol acetate and milbolerone. You should discuss any medication with your veterinarian as these drugs often have significant side effects.

Recovery of Estrus Symptoms After Spaying in Dogs

Most dogs who receive surgery make a full recovery and do not have any further complications. If possible, it’s advisable to treat the condition through surgery, however. The longer the tissue remains in the body, the more likely it is to develop into a cancerous tumor. Studies of groups of dogs with ORS have found a link between the length of time after the original ovariohysterectomy and the development of malignant neoplasia.

If your dog is not able to have surgery, or if the veterinarian is not successful in finding the abnormal tissue, then the condition will have to be managed with medication. Try to use the medication with the least number of side-effects and the lowest possible dose. The behavioral changes in your dog can be difficult to manage, but they are not necessarily hazardous to her health. The main risk with untreated ORS is the increased chance of cancer development and this isn’t greatly affected by medication.

Vaginal Discharge

My dog got spayed almost two weeks ago. We noticed last night she had a bloody discharge from her vagina, then this morning a stringy mucus discharge while peeing. Is this something to worry about?

Thank you for your question. Two years is late in life to be spayed, and if she was in heat or had an infection, there can be hormonal changes for a few weeks afterwards. If this continues, it would be best to have her examined by your veterinarian, as she may have a urinary tract infection or there may be a complication from surgery. This may, however, be normal if she was in heat or pregnant. I hope that all goes well for her.

Thank you for your question. Pregnant spays can be challenging surgeries, and depending on how far along she was, many hormonal changes can occur for a week or two after the surgery. If she continues to bleed, or is urinating more often than normal, it would be a good idea to have a recheck for her, just to make sure that she is okay. I hope that all goes well for her.

Thank you for your question. That is not normal for dogs, no - she may have an infection that can be treated. It would be best to have her seen by a veterinarian, as they can examine her and see where the odor may be coming from, and get treatment so that she is healthy again. I hope that all goes well for her!

Bleeding

My Cockapoo was spayed 18months ago. We have had 3 visits to the vet since with symptoms of swollen vulva and constant licking. The first visit was diagnosed as an infection antibiotics were prescribed. Around 6 months later same symptoms and lactating she was given hormone treatment and antibiotics. The most recent episode was vaginal bleeding I researched this on line and all symptoms pointed to ovarian remnant syndrome. I approached the vet and suddenly after over 900 pounds of tests it is ovarian remnant syndrome. The vet accepts no responsibility Now we are broke and feel very strongly that this is not our responsiblity. How can we fix this.

Vomiting

I found all of this information helpful but it still did not answer the one question that I was coming to find out. I have a 8 1/2 year old pitbull that was spayed a little over a year ago. We took her over to some friends where they had a male boxer and we paid no attention because she was spayed and somehow they manage to still lock... It did not last for long so it wasn't a full on lock but they were stuck together and she was in an immense amount of pain and then today she has been very whiney like in pain and she has vomited several times.... I know that for the 1st few weeks following the slaying ,it could be detrimental and possibly even deadly if a stud is able to get to them, but does this rule still apply year or so after? Please help, I'm low on money but I'm terrified that the stud may have really hurt my Bella

Swollen Vulva And Nipples

We adopted our dog from St. Lucia, where she was spayed at a very young age. She's a year now and the last few months we've noticed her vulva and nipples are enlarged/swollen. Is this likely ovarian remnant syndrome? Or could this be something else? To check if she has ovarian remnant syndrome, is a blood test recommended? If it comes back negative, what else can it be?

Vicious Behavior

My 4yr old Chihuahua was a rescue. She was fine with my other female dog til she went in heat. In heat she started viciously attacking my little dog. We had her spayed while still in heat, about 2 months ago. We brought her home and she is still viciously attack my other baby every chance she gets. I am so distraught and having a bad case of nerves. When I try to separate them it is horrible. It is like she is so zoned out and she has bitten me 4 times and I am scared to death she will kill my Baby. Not to mention the biting hurts horribly. How long does it take for hormones to die down, and what can I do? When not around my Baby, who is 7 years old, she is sweet. But I can not accept this behavior. My Baby has been fixed many years ago, and the other dog has affected my Baby's life style.
