Discover 5 Insights can dogs get monkeypox Your Pet's Safety

The transmission of a pathogen from a human to a companion animal is a phenomenon known as reverse zoonosis or anthroponosis.

This process occurs when a virus or bacterium that primarily circulates within the human population successfully crosses the species barrier to infect a non-human animal.

Such events are most common with animals that live in close proximity to people, as this proximity provides ample opportunity for the pathogen to be shared.

The susceptibility of an animal to a human disease depends on various factors, including the animal’s physiology, the nature of the virus, and the intensity of the exposure.

A well-documented example of this is the transmission of the H1N1 influenza virus from humans to domestic cats and ferrets during the 2009 pandemic.

In another instance, the SARS-CoV-2 virus, responsible for COVID-19, was shown to be capable of infecting a range of companion animals, including cats, dogs, and hamsters, typically after close contact with their infected owners.

These examples demonstrate that the health of humans and their domestic animals is often interconnected, highlighting the importance of understanding how diseases can move between species sharing a common environment.

The study of these transmissions is crucial for both veterinary and public health to prevent further spread and protect vulnerable populations, both human and animal.

can dogs get monkeypox

The question of whether domestic dogs can contract the mpox virus (formerly known as monkeypox) from humans has been a subject of significant concern for pet owners and public health officials alike.

For a long time, the answer was uncertain, with knowledge primarily focused on the virus’s behavior in primate and rodent populations. However, emerging evidence has provided a definitive answer, confirming that human-to-animal transmission is possible.

This discovery has shifted the understanding of the virus’s host range and underscored the need for revised guidance for individuals who are infected and live with companion animals.

A pivotal moment in understanding this risk came in 2022 when a case study published in the medical journal The Lancet documented the first confirmed instance of a dog contracting the mpox virus from its owners.

The case involved two individuals in France who developed symptoms and tested positive for the virus.

Twelve days after the onset of their own symptoms, their four-year-old Italian greyhound began presenting with mucocutaneous lesions, including pustules on its abdomen and ulceration.

This specific and well-documented case provided the first concrete scientific evidence of canine susceptibility.

The symptoms observed in the infected dog were consistent with those seen in human mpox cases, albeit with some variation. The dog developed lesions and pustules, which are hallmark signs of the disease.

In addition to the visible skin issues, the animal reportedly experienced lethargy. The owners noted that they had been co-sleeping with their dog, which created a scenario of prolonged, close contact.

This intimate proximity is believed to have facilitated the transmission of the virus from the owners to their pet, likely through direct contact with skin lesions or contaminated bedding.

To confirm the diagnosis, veterinarians performed rigorous testing on the animal. Samples were collected from the dog’s skin lesions and oral mucosa for analysis.

Polymerase chain reaction (PCR) tests confirmed the presence of the mpox virus in these samples. Furthermore, genomic sequencing was conducted on the virus isolated from the dog and its owners, which revealed a 100% match.

This genetic evidence was irrefutable, proving that the dog was infected with the exact same viral strain as its human companions, solidifying the conclusion of human-to-dog transmission.

Prior to this documented case, the known animal host range for the mpox virus was largely limited to certain species of rodents, squirrels, and non-human primates in Africa, where the virus is endemic.

The 2003 outbreak in the United States, for example, was linked to infected prairie dogs that had been housed with imported African rodents.

The confirmation of infection in a domestic dog represented a significant expansion of this known host range, prompting health organizations worldwide to re-evaluate their public health recommendations concerning pets in infected households.

The primary pathway for transmission from humans to dogs is believed to be direct and prolonged close contact.

The mpox virus spreads through contact with infectious sores, scabs, or body fluids, as well as through respiratory secretions during extended face-to-face interaction.

In a household setting, this can occur when a pet sleeps in the same bed as an infected person, is cuddled or kissed, or shares items like bedding and towels that have been contaminated with the virus.

These common interactions between owners and their pets create multiple opportunities for the virus to be passed on.

Despite the confirmed possibility of transmission, the overall risk for the general dog population is considered low.

The transmission event appears to be rare and has so far only been documented in a setting of very close and sustained contact with highly symptomatic individuals.

This suggests that casual contact, such as a dog passing an infected person on the street, is highly unlikely to result in infection.

The primary risk is concentrated within the immediate household of a person who has an active mpox infection, making preventative measures in this specific environment critically important.

This development has significant implications for both veterinary medicine and public health, reinforcing the “One Health” concept, which recognizes the deep connection between the health of people, animals, and their shared environment.

Health agencies, including the Centers for Disease Control and Prevention (CDC), have updated their guidance for people with mpox, advising them to avoid close contact with pets until they have fully recovered.

This precautionary approach is designed to prevent the virus from establishing itself in new animal populations and to protect the well-being of companion animals.

A remaining area of investigation is whether dogs, once infected, can transmit the mpox virus to other animals or back to humans. Currently, there is no evidence to suggest that this occurs.

The 2022 case was an example of a “spillover” event from humans to an animal, which may represent a dead-end transmission.

However, scientists remain cautious, as the establishment of a new animal reservoir for the virus outside of its endemic regions could complicate efforts to control its spread, making further research in this area a priority.

In summary, the evidence clearly indicates that dogs can, in fact, get mpox from their infected owners.

While this remains a rare occurrence, the confirmed case has provided invaluable insight into the virus’s capabilities and the potential risks to companion animals.

The focus for pet owners should be on prevention through isolation and hygiene if a human in the household becomes infected.

This cautious approach helps protect beloved pets and prevents potential, though currently unproven, pathways for further viral spread in the community.

Key Considerations for Pet Owners

1. Confirmed Susceptibility in Canines

   It is now a scientifically established fact that domestic dogs are susceptible to contracting the mpox virus.

   This conclusion is not based on speculation but on a rigorously documented case study where genetic sequencing confirmed the viral strain in an infected dog was identical to that of its owners.

   This finding fundamentally changes the understanding of the virus’s host range and requires a new level of awareness from pet owners and veterinary professionals.

   The confirmation means that the virus can successfully breach the species barrier between humans and canines under specific conditions of close contact.

2. Transmission Occurs Through Close Contact

   The primary mode of transmission to dogs is through direct, prolonged, and intimate contact with an infected human.

   This includes activities such as sharing a bed, cuddling, licking, or sharing contaminated materials like blankets and towels. The virus is not easily spread through casual or distant interactions.

   Therefore, the risk is almost exclusively confined to the household of an infected person, where the intensity and duration of exposure are highest.

   Understanding this transmission route is key to implementing effective preventative strategies to protect pets.

3. Recognizing Potential Symptoms in Dogs

   If a dog has been exposed to an infected individual, owners should monitor it for signs of illness.

   The symptoms observed in the confirmed case included the development of mucocutaneous lesions, pustules, and ulcers, particularly on the abdomen.

   Other general signs of illness, such as lethargy, fever, or a poor appetite, could also be present.

   Observing any of these signs following a known exposure warrants an immediate consultation with a veterinarian to ensure proper diagnosis and care for the animal.

4. The Overall Public Risk Remains Low

   While human-to-dog transmission is possible, it is important to contextualize the risk as being very low for the broader pet population.

   The virus is not believed to be widely circulating among dogs, and infection appears to be an infrequent event that requires specific circumstances.

   The main concern is not a widespread epidemic among pets but rather isolated instances of spillover within infected households.

   This distinction is crucial for avoiding unnecessary public alarm while still promoting responsible precautions where they are needed most.

5. No Evidence of Onward Transmission from Dogs

   As of now, there is no documented evidence of an infected dog transmitting the mpox virus back to humans or to other animals.

   The infected dog in the primary case study is considered to have been a terminal host, meaning the virus did not spread further from it.

   While this is reassuring, the lack of evidence does not entirely rule out the possibility, and it remains an area for further scientific research.

   Therefore, caution is still advised, and an infected pet should be isolated from other animals and people as a precautionary measure.

Preventative Measures and Guidelines

• Isolate from Pets if Infected

  An individual diagnosed with mpox should immediately limit contact with all pets in the household. This involves avoiding activities like cuddling, kissing, and allowing the pet to lick them.

  Ideally, the infected person should not share a bed or other furniture with the animal.

  If possible, another healthy member of the household should take over all responsibilities for pet care, including feeding, walking, and grooming, to minimize any chance of exposure.

  This physical separation is the single most effective step in preventing transmission.

• Practice Enhanced Household Hygiene

  Maintaining strict hygiene is crucial in a household with an active mpox infection to prevent transmission through contaminated surfaces, known as fomites.

  This includes frequent handwashing with soap and water, especially before and after interacting with a pet or its supplies.

  All bedding, clothing, and towels used by the infected person should be handled carefully and washed separately from the pet’s items.

  Regularly disinfecting high-touch surfaces can also help reduce the amount of viable virus in the shared environment.

• Monitor Your Pet’s Health Closely

  If a pet has been exposed to an individual with mpox before isolation measures were implemented, the owner should monitor its health carefully for at least 21 days.

  This involves daily checks for any skin lesions, pustules, or changes in behavior such as lethargy or loss of appetite. Keeping a simple health log can be helpful for tracking any potential symptoms.

  This proactive monitoring allows for early detection and prompt veterinary consultation if the animal does show signs of illness.

• Consult a Veterinarian Promptly and Safely

  Should a pet develop symptoms consistent with mpox after a known exposure, it is imperative to contact a veterinarian right away.

  However, it is equally important to call the veterinary clinic in advance to inform them of the situation.

  This allows the clinic staff to prepare and implement appropriate biosecurity protocols, such as arranging to see the animal in an isolated area, to prevent any potential spread within the facility.

  Do not bring a potentially infected pet to a clinic without prior notification.

The confirmation of mpox in a domestic dog serves as a powerful real-world example of the “One Health” principle.

This approach to public health recognizes that the well-being of humans, animals, and the environment are inextricably linked. Zoonotic and reverse zoonotic diseases highlight the vulnerabilities at the human-animal interface, especially within our own homes.

Addressing these threats requires collaboration between human medical doctors, veterinarians, and environmental scientists to create comprehensive strategies for disease surveillance, prevention, and response that protect all species.

The mpox virus itself is not new, having been first identified in laboratory monkeys in 1958, with the first human case recorded in 1970.

For decades, it was primarily a rare disease found in remote parts of Central and West Africa.

The 2022 global outbreak marked a significant shift in its epidemiology, with sustained human-to-human transmission occurring in non-endemic countries around the world.

This change in the virus’s behavior brought new questions to the forefront, including how it might interact with companion animal populations that had never been exposed before.

Placing canine susceptibility in a broader context is helpful. The natural reservoirs for the mpox virus are believed to be small African rodents and squirrels. The 2003 U.S.

outbreak, which infected dozens of people, originated from a shipment of infected Gambian pouched rats that were housed near prairie dogs.

The prairie dogs became infected and subsequently passed the virus to humans who purchased them as pets.

This history shows that the virus can adapt to various mammalian hosts, so the finding of susceptibility in a canine, while new, is not entirely surprising from a virological perspective.

Veterinary public health plays a critical role in managing diseases that cross the species barrier.

Professionals in this field are responsible for monitoring animal populations for signs of disease, conducting research on zoonotic pathogens, and developing guidelines to protect both animal and human health.

The human-to-dog mpox case has prompted these experts to work closely with human health agencies to create unified recommendations for infected pet owners, ensuring that advice is consistent, practical, and based on the best available science.

Diagnosing mpox in a dog involves procedures similar to those used for humans.

A veterinarian would likely suspect the disease based on the animal’s clinical signs combined with a history of exposure to an infected person.

To confirm the diagnosis, the veterinarian would carefully collect samples by swabbing the animal’s skin lesions.

These samples are then sent to a specialized laboratory for PCR testing, which can detect the virus’s genetic material with a high degree of accuracy, providing a definitive diagnosis.

Should a dog be diagnosed with mpox, there is currently no specific antiviral treatment approved for use in animals.

Therefore, veterinary care would focus on supportive measures to help the animal’s immune system fight off the infection.

This can include managing skin lesions to prevent secondary bacterial infections, ensuring the dog remains well-hydrated and nourished, and providing pain relief if necessary.

The infected animal would also need to be kept in strict isolation to prevent any potential, though unproven, risk of further transmission.

The emotional and psychological toll on an infected pet owner can be substantial. The fear of having transmitted a painful illness to a beloved companion can cause significant guilt, anxiety, and stress.

It is important for public health messaging to be empathetic, providing clear, non-judgmental guidance on how to care for both oneself and one’s pet.

This situation underscores the deep human-animal bond and the need for support systems that address the comprehensive well-being of the entire household during a health crisis.

Looking ahead, more research is essential to fully understand the dynamics of the mpox virus in dogs and other domestic animals.

Key questions remain regarding the full spectrum of clinical signs, the typical duration of illness, and the level of viral shedding from an infected animal.

Furthermore, surveillance studies could help determine if the 2022 case was an extremely rare event or if other, milder cases in pets have gone undetected.

Answering these questions will allow for more refined public health and veterinary recommendations in the future.
