Herpes in dogs: an overview

Herpes in dogs is a common and often misunderstood problem. In this article we want to provide you with comprehensive information and clear up some common myths. Our information is based on scientific findings and practical experience.

What is Canine Herpesvirus?

Canine herpesvirus is a specific virus that can infect dogs. It remains permanently in the animal's body, often without causing symptoms. However, it can be reactivated during times of stress or illness and lead to various problems.

Symptoms of herpes in dogs

Symptoms in puppies

Canine herpesvirus can cause very serious symptoms in puppies, especially if they are younger than three weeks old.

1. Apathy and Weakness : Infected puppies are often listless and show little interest in playing or eating.
2. Panting and shortness of breath : The respiratory tract may be affected, causing shortness of breath.
3. Screaming noises : Sometimes the puppies make painful noises.
4. Bluish discoloration of the mucous membranes : This is a sign that the puppy is not getting enough oxygen.
5. Low weight : Infected puppies often do not gain weight well and lag behind their littermates.
6. Death : Unfortunately, in very young puppies the infection often results in death within 24 to 48 hours.

Symptoms in adult dogs

Adult dogs are mostly resistant to the clinical effects of the virus but can be carriers. If symptoms occur, they might look like this:

1. Breathing problems : Coughing or sneezing could be a sign of infection.
2. Genital problems : The virus can cause inflammation of the genital organs.
3. Fever : A mildly elevated fever can occur, but is rare.
4. Birth of dead or weak puppies : Infected bitches may give birth to puppies that are already dead or appear very weak.

Symptoms in pregnant bitches

1. Abortion : The infection can lead to a miscarriage.
2. Birth of Weak Puppies : As with adult dogs, the infection can cause the puppies to be born weak and susceptible to disease.

Diagnosis of herpes in dogs

1. History and clinical examination

The veterinarian will first speak with the dog's owner to determine the dog's medical history and possible symptoms. This can indicate a possible infection with the Canine Herpesvirus (CHV). Afterward, the veterinarian will physically examine the dog to identify symptoms such as fever, eye or nasal discharge, cough, or general weakness.

2. Sample collection and laboratory tests

If the veterinarian suspects a canine herpesvirus infection, he or she may take a sample of body fluids such as saliva, nasal discharge, or urine. These samples are then sent to a laboratory where special tests are carried out to identify the virus.

3. PCR test

The PCR (polymerase chain reaction) test is a specific method to detect the presence of CHV. It allows the precise identification of the virus at the DNA level.

4. Serological tests

Serology tests can also be used to find antibodies to the virus in the dog's blood. The presence of antibodies may indicate a previous or current infection.

5. Assessment of accompanying symptoms

In some cases, the veterinarian may also perform additional tests to evaluate accompanying symptoms or secondary infections. This could include x-rays or blood tests.

6. Differential diagnosis

Because the symptoms of canine herpes can be similar to other diseases, the veterinarian may perform a differential diagnosis to rule out other possible causes.

Canine Herpes Transmission: A Deeper Look

Herpes in dogs, caused by the canine herpesvirus (CHV), is a common disease that occurs primarily in puppies in the first few weeks of life. But how is this virus transmitted? Here is the key information to better understand the transmission routes.

Orally

The oral route is one of the most common routes of transmission for the canine herpes virus. It can spread through contact with infected secretions such as saliva, nasal and eye secretions.

During mating

The virus can also be transmitted during mating, when an infected dog is crossed with a healthy partner. The infection can then be passed on to the puppies in the womb.

From mother to puppy

The puppies can also become infected in the womb if the mother is infected with the virus. This route of transmission is particularly dangerous for puppies because their immune systems are not yet fully developed.

Through the environment

The virus is also shed in vaginal secretions and semen, which can contaminate the environment. The dogs can then pick up the virus through contact with these surfaces.

Direct contact with infected littermates

If one puppy in the litter is infected, the virus can be quickly transmitted to its siblings because the puppies are in close contact with each other in the first few weeks of life.

Protection against herpes in dogs

The best protection against a herpes infection in dogs is prevention. This can be achieved through vaccinations, hygiene measures and careful handling of potentially infected animals.

Treatment of herpes in dogs

Therapy for puppies

Because puppies are particularly vulnerable to the serious effects of the virus, treatment must be administered quickly and carefully.

1. Warmth : Infected puppies often need extra warmth because their body temperature may be too low. Heat lamps or heated blankets can help maintain the right temperature.
2. Respiratory support : Oxygen therapy may be necessary if the respiratory system is affected.
3. Hydration : IV fluids may be necessary to maintain fluid balance, especially if the puppy does not want to eat or drink properly.
4. Antiviral medications : Antiviral medications can sometimes be prescribed, but their effectiveness in puppies is not always guaranteed.

Therapy for adult dogs

For adult dogs, therapy is often less intensive because the symptoms are usually milder.

1. Symptomatic treatment : Things like cough or fever can be treated with appropriate medications.
2. Antibiotics : If there is an additional bacterial infection, the vet may prescribe antibiotics.

Therapy for pregnant dogs

1. Support during pregnancy : Monitoring and support during pregnancy can help ensure the puppies' health.
2. Cesarean section : In some cases, a cesarean section may be necessary to save the puppies if the female dog is infected.

prevention

In addition to treatment, prevention is important. This includes:

1. Isolation of infected animals : To prevent spread, infected animals should be isolated.
2. Vaccinations : There are vaccinations that can help prevent the infection, especially if there is a known outbreak in the area.

Preventive measures against herpes in dogs

1. Vaccination : There are special vaccinations that can protect against the canine herpes virus. Talk to your vet about whether a vaccination makes sense for your dog.
2. Hygiene : Make sure your dog's environment is clean and hygienic. The virus can spread more easily in dirty conditions.
3. Avoiding contact with infected animals : If you know another dog is infected with herpes, keep your dog away to avoid infection.
4. Regular check-ups : Regular vet visits help detect possible infections early and treat them accordingly.
5. Healthy diet and lifestyle : A balanced diet and sufficient exercise strengthen your dog's immune system, which helps him fight off infections.
6. Controlling Breeding Conditions : If you plan to breed your dog, you should pay particular attention to the health of all animals involved. The virus is particularly dangerous for puppies, so extra precautions are required here.
7. Attention to symptoms : If you know the symptoms of herpes in dogs and recognize them early, you can act quickly and prevent the virus from spreading.
8. Sharing information with other dog owners : Sometimes it is helpful to share experiences with other dog owners and find out about the latest findings.

With these measures you can minimize the risk of herpes infection in your dog. If you have any further questions or concerns, it is always good to speak vet

Frequently asked questions (FAQs) about herpes in dogs

What is Shingles?

Shingles, also known as herpes zoster, is caused by the varicella-zoster virus (VZV). This is the same virus that causes chickenpox. In people who have already had chickenpox, the virus can lie dormant in nerve cells and reappear later in life as shingles.

Is shingles contagious for dogs?

The short answer is: No, shingles is not contagious to dogs.

Why is that?

1. Specificity of the virus : Varicella-zoster virus is a human virus that is specifically targeted to humans. It has no effect on dogs or other pets.
2. No interspecies transmission : Even if a human has shingles and has close contact with their dog, there are no known cases of the virus being transmitted to the dog.
3. Other herpesviruses in dogs : Dogs can be infected by the canine herpesvirus, but this is a completely different virus and is not related to the varicella-zoster virus in humans. The symptoms and treatments also differ.

Precautions

Although shingles is not contagious to dogs, it is important to follow hygiene measures if you have shingles yourself. This applies to the transmission of the virus to other people rather than to pets.
