Why Do Dogs Lick Their Vagina and What It Reveals About Their Health?

Why Do Dogs Lick Their Vagina and What It Reveals About Their Health?

The female dog's reproductive tract's external section is termed the vulva. Why Do Dogs Lick Their Vagina? This structure comprises two labia, which are robust tissue folds connected at both the top and bottom. Just inside the vulvar opening lies the vestibule. The vagina and the urethra, responsible for draining the bladder, both open into this vestibule. Progressing further, the vagina links with the cervix, which subsequently connects to the uterus.

Recognizing a Healthy Canine Vagina

To discern any abnormalities in your dog's vagina, it's crucial to be familiar with its healthy appearance. The vulva should be visible. For unspayed female dogs, the vulva's appearance can undergo significant changes throughout its heat cycle. During the heat phase, where the dog is receptive to mating, the vulva enlarges, accompanied by a noticeable bloody discharge. This phase typically spans a week or two, but the duration can differ among dogs. Post this phase, the bleeding ceases, and the vulva reverts to its usual appearance. This cycle might recur every four to twelve months.

Concerns When the Vulva Isn’t Visible

If the vulva isn't immediately visible and requires skin separation for a clear view, it indicates a problem. Excess skin enveloping the vulva can instigate urinary tract infections, vaginal infections, and dermatitis on the surplus skin. In advanced stages, the dog might not exhibit any symptoms. In severe cases, surgical intervention might be necessary to eliminate the excessive tissue.

Identifying Vaginal Infections in Dogs

Dog owners frequently express concerns about potential vaginal infections in their pets. Indications of a vaginal infection, or vaginitis, encompass:

  • Vulvar discharge, possibly with pus or blood
  • Persistent vulva licking
  • Dragging the hindquarters on the ground
  • Increased urination frequency
  • Discomfort during urination
  • Attraction from male dogs outside the heat cycle

Underlying Causes of Vaginal Infections

Vaginal infections can arise from various sources. While bacteria or other pathogens might be the primary culprits, infections can also emerge due to other health complications. Factors such as vaginal trauma, foreign objects, anatomical anomalies, tumors, urinary tract issues, and hormonal imbalances can instigate vaginitis.

Vaginitis in Puppies

Puppies, before experiencing a heat cycle, can manifest a condition termed puppy vaginitis, exhibiting symptoms akin to the ones mentioned above. Allowing the puppy to undergo one heat cycle before spaying typically resolves this condition. However, if vaginitis is suspected, it's advisable to consult a veterinarian.

Reasons for Excessive Vulva Licking

Occasional vulva licking by a dog is a natural cleaning behavior. However, if this action becomes incessant or is accompanied by a vaginal discharge, changes in vulva appearance, or deteriorating overall health, it might indicate infections, injuries, or other complications in the urinary or reproductive system. In such scenarios, a veterinarian's consultation is recommended.

Addressing Bloody Discharge

A bloody discharge is a standard occurrence during a female dog's heat cycle, which usually happens 1-3 times annually. However, if a spayed dog exhibits bleeding or an intact dog bleeds outside her heat cycle, it might signify a grave health concern. Potential causes include trauma, tumors, infections, anatomical issues, blood clotting disorders, or urinary tract conditions. It's imperative to seek a veterinarian's evaluation in such cases.

Assessing Vulva Swelling

A non-spayed female dog's vulva naturally swells during her heat cycle, reverting to its standard size post the cycle, which can last between 2-21 days. However, conditions like vaginal hyperplasia can cause dark pink or red tissue to protrude from the vulva. This swelling typically subsides post the heat cycle or post-spaying. If a spayed dog's vulva appears swollen with a bloody discharge, residual ovarian tissue might be present post the spaying procedure. Other causes of swelling include infections, injuries, and tumors. If a dog's vulva swells outside her heat cycle, it's crucial to consult a veterinarian.

Evaluating Color Changes

The dog's labia external surfaces are skin-covered with sparse hair, resembling the adjacent skin and hair. Some dark staining might be evident due to fluids like saliva, which oxidizes to a reddish-brown hue. The labia's inner surfaces are typically pink and aren't usually visible. Any color alterations or discharges warrant a veterinarian's appointment to eliminate potential health risks.

Deciphering Vaginal Discharges

A dog in heat will exhibit a bloody vulva discharge, while a post-partum dog might have a dark green to black discharge. However, other discharge types, which could be watery, bloody, mucous-like, or pus-filled, usually indicate health issues. Potential causes include:

  • Traumatic injuries
  • Pregnancy or birth complications
  • Foreign objects in the vagina
  • Infections in the urinary or reproductive system
  • Uterine infections, such as pyometra
  • Urinary or reproductive tract cancer
  • Urinary tract stones
  • Blood clotting anomalies
  • Anatomical issues
  • Hormonal imbalances

A healthy dog's vulva should have minimal odor. Any unusual smell or sight in this region necessitates a veterinarian consultation.

Addressing Rashes Around the Vulva

The skin surrounding a dog's vulva can develop rashes akin to other body parts. Given that the vulva contacts the ground when a dog sits, it's frequently exposed to irritants, allergens, and biting insects. Parasites or skin infections can also induce rashes. A cool water bath with mild soap might alleviate rashes caused by allergens or irritants. However, persistent, severe, or highly discomforting rashes should be assessed by a veterinarian.

Investigating Lumps or Growths

Any lumps, bumps, or growths around a dog's vulva are abnormal and might be linked to injuries, infections, anatomical issues, inflammation, cysts, or tumors. Unspayed dogs might develop a condition called vaginal hyperplasia, characterized by dark pink or red swollen tissue protruding from the vulva. This swelling typically diminishes post the heat cycle or post-spaying. Any concerns regarding a dog's health should be addressed with a veterinarian.
