Reasons why female dogs lick their private areas

The first thing we need to know is that it is normal for a dog to lick her privates under many circumstances. Dogs are self-grooming and will lick and bite any part of their body they think needs to be cleaned. There are some circumstances were licking their genitals may be a sign of a problem. Whether normal or abnormal, a dog will lick her privates due to:

  • Pleasure
  • Stress and hormones
  • Infection
  • Vaginitis

We look at all the possible reasons for a dog licking her private area in more detail in the sections below. Licking their privates is not the only reason they may lick. Check out our article on why my dog keeps licking me to find out more.


A female dog or bitch usually reaches sexual maturity between six months and one year of age. Sexual maturity comes with the arrival of their first heat. From this moment onward you may begin to notice new behaviors in your dog, such as humping stuffed animals, blankets or other dogs and intense licking of her private parts. This behavior is normal and part of canine nature, but why? The answer is simple: to masturbate and give themselves pleasure. Female dogs also lick their privates more often each time they are in heat, as we will explain later.

Like women, bitches have a clitoris inside of their vulva, an organ whose sole function is to give pleasure. Being located inside the vagina, we rarely see it, but in some dogs it is visible as a round and reddish bump. If you see this, you shouldn't worry. You should only be alarmed if practically the whole clitoris of is protruding through the vulva or if you notice an unusual lump on the dog's vulva. In addition, if your dog’s vagina is swollen, irritated or presents abnormalities we suggest consulting a specialist as soon as possible.

Therefore, once a dog has experienced the pleasure of licking her vagina, which can be at any point in her life, it is completely normal to see her licking it often. This licking might last for a few seconds or minutes with intensity and your female dog might also emit a kind of moaning sound. However, if this action becomes habitual or compulsive, we recommend consulting a professional.

Stress and hormones

In relation to the previous point, if we observe a female dog licking her genital area extensively and does it compulsively, it may be an indicator of stress. When a dog is stressed, they try to release tension through behaviors that, in many cases, can be misdiagnosed. In the case of female dogs, one of the ways to relieve tension, stress or anxiety is by licking the vagina. Thus, it is essential to identify what is causing your dog stress to both avoid and solve the problem. If not enough attention is given and the dog's stress is not treated, this habit may become a stereotypy - persistent abnormal behavior - making it more difficult to treat[1].

Another reason that may explain why your dog is licking her vagina with great intensity is hormonal imbalance. Hormonal imbalances in dogs can also cause the development of stress, resulting in the aforementioned consequences. This happens in bitches that have not yet been sterilized. Therefore, if you suspect that your dog may be suffering from a hormonal imbalance, you will have to go to the vet to evaluate the option of having surgery.


If your female dog licks her private area a lot and is also experiencing whitish or slightly yellowish vaginal discharge she may be suffering a serious health problem. In such cases you should consult the vet immediately. The most common diseases and conditions cause excessive vaginal licking along with abnormal discharge are:

  • Pyometra (infection of the uterus)[2]
  • Matrix infection
  • Ovarian infection
  • Bacterial infection
  • Fungal infection
  • Wounds in the vagina and/or cervix

However, these are not the only diseases that can cause pus secretion from the vulva. In fact, almost any infection of a bitch's lower reproductive apparatus can present this symptom. The exact type of infection needs to be diagnosed and treated by a professional, so it is best to consult your vet at once.

Pyometra is both a relatively common and potentially life threatening disease which affects the canine uterus. For this and other reasons, it is common to sterilize the dog. In fact, most of the possible reasons why a dog licks her privates can be address through ovariohysterectomy. Our article on whether a spayed dog can get pyometra can help you learn more.


If you notice that the bitch's vulva is swollen (vaginitis), this generally indicates she is on her estrus period. From the first stage of her period, the dog's vulva increases in size and you will see initial bleeding, which causes her to lick her genital area constantly. If you notice this behavior while the dog is on her heat period, you can be sure that this is the reason for both the licking and inflammation of her vagina.

However, if your dog is not presenting typical heat symptoms, but presents with vaginitis and licks her vagina constantly, look out for the following symptoms:

  • Increased urination
  • Difficulty urinating
  • Crying
  • Loss of appetite
  • Mood changes

These symptoms indicate that she may be suffering from a urinary tract infection or canine cystitis. Such diseases, along with vaginal tumors, ovarian cysts or other pathologies, can only be diagnosed by a specialist. Therefore, if you suspect that any of these may be the reason for your dog licking her private area, do not hesitate to visit your veterinarian as soon as possible.
