What is Vaginal Hyperplasia?

If you have a female dog, it is possible that you may have to deal with this condition, especially if your dog is not spayed.  Some dog breeds are more susceptible than others. However, when and if you do notice this, your responsibility as a pet owner is to take action right away by taking your dog to the veterinarian for a proper diagnosis and treatment.

An enlarged and inflamed vaginal lining that is influenced by estrogen is known as vaginal hyperplasia. When the vaginal mucosa swells up like this, it visibly bulges out of the vaginal lips.

Symptoms of Vaginal Hyperplasia in Dogs

The noticeable sign and symptom is a tongue-like bulge, protruding through the dog’s vulva.  Other symptoms include:

  • Pain during urination
  • Extreme licking of the vulva
  • Noticeable tissue at the opening of the vagina
  • Swelling of the tissue
  • Difficulty with having puppies during delivery

If your dog is pregnant and ready to give birth, pushing to deliver the puppies may result in the bulging and swelling of the tissues. In fact, this can create a blockage when your dog is ready to deliver her puppies. This should be considered a medical emergency where a C-section should be undertaken. If not, then the mother and the pups may be at risk. Therefore, a veterinarian should be consulted for medical assistance.

  • German Shepherd
  • Boxer
  • Labrador Retriever
  • Mastiff
  • Airedale Terrier
  • Springer Spaniel

Diagnosis of Vaginal Hyperplasia in Dogs

It is important for you as a pet owner to realize the severity of the problem and get your dog to the veterinarian as early as possible. Your veterinarian will provide a proper diagnosis upon assessing the symptoms. Most veterinarians believe that vaginal prolapse and heightened estrogen levels are connected. The reason for this observation and conclusion is that the condition usually happens prior to the dog’s heat cycle where estrogen levels are higher. 

If the condition is severe, it could result in prolapse where the tissues are visible. Of course, the obvious signs of swollen and bulging vaginal tissue in a female dog is an indication that vaginal hyperplasia is the proper diagnosis. Make sure to provide the veterinarian with further information, including the dog’s breed and how long and the instances when your pet has experienced vaginal hyperplasia.


If there is concern for neoplasia, a biopsy of the tissue will be taken.

Treatment of Vaginal Hyperplasia in Dogs

Mild cases do not need any treatment and will resolve of their own accord.

Don’t feel overwhelmed, though, because successful treatment is possible. The veterinarian will clean the vaginal area and use antibiotic cream to lubricate the area, preventing drying. If your goal is not dog breeding, then the veterinarian may recommend spaying to eliminate the risk of future problems. If you are going to breed your dog, then artificial insemination would be the ideal choice. If the condition is severe, the veterinarian might consider suturing to get the mass returned to the vagina, after which it would subside once the heat cycle has been completed. The veterinarian will also make a decision whether to surgically take out the dead tissue. Doing so will avoid a reoccurrence of hyperplasia. 

Hormone therapy is also an option if your dog has not had any damage to the vaginal tissue and once urination is possible. Hormone therapy will accelerate the heat cycle and correct the vaginal prolapse. The veterinarian may apply topical cream to the area to reduce the swelling.


Use a buster collar to prevent any licking.

Recovery of Vaginal Hyperplasia in Dogs

After treatment, a vaginal prolapse may recur, especially during the next heat cycle if unspayed. In the meantime, you should help your dog during the recovery process by continuing the use of  any topical creams. Your veterinarian will recommend that you consider the idea of spaying your dog. Pay attention to your pet to ensure that there is no biting or licking of the area. You may have to buy a cone collar to help with this.

Vaginal hyperplasia can be expensive to treat. To avoid high vet care expenses, secure pet health insurance today. The sooner you insure your pet, the more protection you’ll have from unexpected vet costs.

I'm sorry your dog is unwell. I'm not entirely sure what you mean by her vagina is 'swollen hanging' but I would be concerned for e.g. a prolapse. A vet visit is needed for both her and the puppies sake if the labour is not progressing as normal. Let the vet know about any financial concerns beforehand and they should be able to work with you.

Hello this could be her coming into heat, urinary tract infection or vaginal infection. It would be best for your vet to look at her. They can start her on antibiotics for any infection.
