Can Dogs Get Genital Herpes?

We’ve all heard of the scourge of genital herpes in humans, but what about dogs? Can your four-legged best friend get genital herpes?

In humans, genital herpes is one of the most common forms of sexually transmitted diseases. Most humans do not exhibit any symptoms. However, some may suffer from the occasional outbreak of sores around the genitals.

Can Dogs Get Genital Herpes?


Dogs most certainly can get genital herpes. However, even if your dog does have genital herpes, you may never know it. Most adult dogs with the canine herpesvirus (CHV) never show so much as a single symptom.

CHV is also known as "fading puppy syndrome". It is a viral syndrome that is known to infect an adult dog's reproductive organs. Although most adult dogs do not show any real symptoms, CHV is considered the leading cause of death in newborn puppies.

There is no scientific data to suggest that humans can give herpes to dogs or vice versa as the two strains of this disease are not the same. If you suspect your dog might have CHV, you should take him to the vet for bloodwork to determine if he has the disease. If he or she tests positive, you should avoid breeding as it can be passed on to any puppies and may cause their death.

Does My Dog Have Genital Herpes?


The reality is that most adult dogs never display any symptoms of genital herpes and those they do manifest tend to not stick around for very long. However, there are a few symptoms you should be on the lookout for:


In both sexes:

  • Sores and ulcers around the genitals, mouth, and face

  • Upper respiratory issues

  • Kennel cough

In females:


  • Abortion or reabsorption of fetuses

  • Stillborn fetuses


Canine genital herpes virus lives in vaginal secretions of females, semen of males, and in the respiratory systems of both sexes. There are three ways in which your dog may contract CHV:

  • Airborne, by inhaling CHV

  • Eating anything contaminated with CHV

  • Mating with another dog that already has CVH


  • In the event a puppy dies shortly after birth or is stillborn, the vet should perform a necropsy to determine the cause of death.

  • Adult dogs are typically tested for the herpes virus if they are going to be used for breeding or if anything in their history indicates they might be carrying the virus.

  • Your vet may also recommend a blood test if you suspect your dog may have been exposed to the virus.

How Do I Treat My Dog's Genital Herpes?

In most cases, the best form of treatment for genital herpes in adult dogs is to simply let the virus run its course.


There are no known forms of effective treatment to cure CHV; once contracted, your dog will always be a carrier in much the same way as humans.

  • In adult dogs, rest and plenty of TLC are the only treatment needed to help your dog get past the outbreak

  • In puppies, the vet may try to keep them warm, feed them intraorally and may try giving them a serum created from the blood of a dog who has recently recovered from an outbreak of the virus.

  • The simple reality is that most puppies with CHV die within a few days and those that do survive tend to have heart damage and nervous system disorders.


  • Adult dogs who get plenty of rest and good nutrition will recover quickly from an outbreak.

  • Adults may become carriers for the rest of their lives

  • Females may have litter that might be healthy or could be infected with the virus

  • Puppies have a very slim chance of surviving being born with herpes

  • Puppies that do survive typically have neurological defects

How is Genital Herpes Similar in Dogs and Humans?

Although the actual herpes viruses in humans and dogs are very different, there are a few similarities between genital herpes in people and dogs, including:

  • Blisters, sores, and ulcers around genitals, anus, mouth

  • Flu-like symptoms

  • Most dogs and people show few, if any signs, they have the virus

However, just because your dog is not displaying any symptoms of the virus does not mean you should not have him or her tested, especially if you plan to use your dog for breeding purposes.

How is Genital Herpes in Dogs Different to Humans?

There are a few major differences in how herpes affects dogs in comparison to how it affects humans.

  • Female dogs with herpes may reabsorb their fetuses

  • The human body does not commonly reabsorb a fetus

  • Female dogs may have stillborn pups

  • Puppies born with CHV have a very high death rate  

  • Neonatal herpes is not typically fatal in human babies

  • Female dogs pass herpes on to their puppies

  • There is less than a 0.1 percent chance of herpes being passed from mother to human baby

Case Study

Everything seemed to indicate the dog's pregnancy was going along quite normally. She had never shown any signs of being ill before or during her pregnancy and had plenty of energy up until the last few days.

On the night of delivery, things seemed to be progressing normally until all but one of the pups was stillborn. The one that did survive died within hours.

All of the puppies were taken to the vet for a necropsy. The results indicated each of the puppies was infected with the canine herpes virus. Upon testing, it was found that the mother carried the virus without showing any signs or symptoms that might indicate she had a problem.

Be sure to have your dogs tested regularly for CHV and if he or she is taken to a kennel or doggy daycare on a regular basis, you might recommend that all other dogs they come into contact with be tested.
