Why Is My Dogs Vagina So Big

Allergic Response

It’s possible that your dog has an allergy to the shampoo or other grooming supplies you use. Another possibility is that your dog has come into contact with a plant or bug that is triggering an allergic reaction. The vulva is a delicate area that might react to plant toxins or insect venom. It is best to take your dog to your veterinarian’s office so they can identify the ailment and recommend a course of therapy because the cause is unknown.

Once or twice a year, a female dog that hasn’t been spayed may experience an estrus phase that lasts for around three to four weeks. For your dog, this is entirely natural. During this time, estrogen is produced, which causes the tissues to grow and turn away from the vulva. This can be avoided by spaying your dog, which also renders your dog incapable of reproducing.

If your dog is pregnant, changes in the vulva, which are frequently mistaken for enlargement, will mark the start of the labor preparation process. This is typical of childbirth.

When pulling dogs apart during mating, the female may suffer harm.

The tie must be broken by the male dog’s ejaculation in order for them to be able to part ways.

Female dogs are more likely than male dogs to have urinary tract infections. Probiotics or antibiotics can help treat an infection and stop the swelling from getting worse. Juvenile (puppy) vaginitis and adult-onset vaginitis are two different kinds of vaginal canal inflammation. The appropriate medication will be prescribed by your veterinarian to treat the infection. It is vital to identify this issue early because, if neglected, it can require surgical cleansing and draining to fix.

Why is the private part of my girl dog swollen?

The vulva of an unspayed female dog will enlarge as part of her typical heat cycle, but it should shrink back to normal size once the heat is through (anywhere between 2-21 days is considered normal).

Dark pink or red tissue may protrude from the vulva if your dog has a condition known as vaginal hyperplasia. When the heat cycle is through, the tissue swelling that caused this should go away. Additionally, having your dog spayed will solve the issue and stop it from happening again.

It’s likely that some ovarian tissue persisted in the belly of your spayed female dog if she has a large vulva and a bloody discharge.

A dog’s vulva may appear swollen due to infections, trauma, or tumors.

If your dog’s vulva is swollen and you are aware that she shouldn’t be in heat, call your veterinarian for help.

Why is the private area of my dog so big?

If you find that your female dog’s private area is bloated, it may be an indication of labor, an allergic response, an illness, or your fluffy companion commencing her heat cycle. The six causes of enlarged private parts in female dogs are listed below.

Estrus cycle

Your female dog will go into heat twice a year for roughly 3–4 weeks if she is still intact. The tissues surrounding the vulva will enlarge and face outwards during this time due to the dog’s body releasing more estrogen hormones.

Other common indications that a dog is in heat besides swelling in the intimate area include:

  • Vaginal discharge with a bloody tint
  • genital licking that is excessive
  • excessive tail waggishness
  • a rise in mountain behavior
  • open to having male dogs lick and sniff her vulva
  • frequent urinating, frequently in male dogs’ presence
  • conduct that is agitated, anxious, or nesting

If the female dog’s vulva is enlarged and you see the majority of the symptoms listed above, your dog is most likely in heat. If the mating is successful, she will get pregnant. After the heat is passed, however, the vulva should grow back to its original size (within 2-21 days).


Infections of the urinary system are common in female dogs. For instance, older dogs and puppies may suffer from vaginitis, an inflammation of the vaginal region. Bacterial infections, structural defects, and even malignancy are all potential causes of the illness.

Vaginal inflammation comes in two different forms: juvenile vaginitis, which affects puppies, and adult-onset vaginitis (which affects older dogs and is more common in spayed female dogs).

In dogs, symptoms of vaginal inflammation include:

  • Yellowish or white vaginal discharge
  • vulva region licking that is excessive
  • often urinating
  • discomfort indicators when urinating
  • a crimson vulva that has swollen
  • Dog moving down the floor with her bottom.

Take your female dog to the vet for an inspection and treatment if you suspect vaginal irritation. If the problem is not handled in a timely manner, corrective operations including surgical cleansing and draining may be required.

Vaginal hyperplasia

When your dog is in heat, vaginal hyperplasia, a disorder, can also occur. As a result of tissue swelling in the vaginal region, you will see a dark pink or crimson tissue protruding from her vulva. Once the heat cycle is over, this situation ought to go away. If you don’t want your dog to become pregnant, you can choose to spay her, which will also stop vaginal hyperplasia.

Some female dogs who have had spaying still endure vaginal bleeding and vaginal edema. This happens when, following her spay operation, some ovarian tissue is still present inside the abdomen. If your dog’s private region is bloated and there is a vaginal discharge that has a bloody tint, be sure to take her to the doctor.

Labor sign

Your female dog’s private area may be enlarged as a result of pregnancy preparation. One of the changes you’ll notice in your pregnant dog as she approaches labor is enlargement of the vulva, which is one of the alterations. Other indications that a dog is giving birth include:

  • Nervousness and restlessness
  • panting while pacing
  • refusal to eat and possible vomiting
  • Nesting actions, such as dragging clothing and fabric to create a cozy bed
  • The woman strains as her stomach tightens.

A female dog’s nipples will have grown larger in preparation for breastfeeding by the time she goes into birth.

Forced separation during mating

A copulatory knot, or getting stuck during mating, occurs in dogs. The male dog’s bulbous head grows as soon as his penis is inserted, “holding him to the female.” Only once the male dog ejaculates and his enlarged head shrinks down to normal size will the knot be broken, allowing him to leave.

The female dog may suffer injuries such as tearing of the vaginal area, internal damage, blood loss, and severe agony if canines trapped in the mating process are forcibly separated. The best course of action is to see a veterinarian because these wounds cause the vulvar area to enlarge.

Allergic reaction

Your female dog’s private area swelling could possibly be the result of an allergic response. It’s possible that your dog has an allergy to shampoo or that she got into contact with a plant that she is allergic to. Remember that the vulva is a sensitive area that can react to plant toxins or insect stings.
