Can Dogs Catch Stomach Viruses from Humans and the Risks Involved

Dogs can catch stomach viruses from humans, and it's more common than you think. According to research, humans can transmit stomach viruses like norovirus and rotavirus to dogs through contaminated food, water, and surfaces.

Dogs are highly susceptible to norovirus, a virus that causes stomach flu in humans. In fact, a study found that dogs can shed norovirus for up to 14 days after infection, making them potential carriers of the virus.

The risks involved are serious, especially for puppies, older dogs, and dogs with weakened immune systems. These dogs are more likely to develop severe symptoms, such as vomiting, diarrhea, and dehydration, if they contract a stomach virus from a human.

If you're wondering whether dogs can catch stomach viruses from humans, the answer is yes, they can. In fact, studies have shown that norovirus can be transmitted from humans to dogs, particularly through oral contact with contaminated surfaces or food and drink.

Norovirus can spread quickly, especially in households where multiple people are infected. If you're experiencing symptoms, it's essential to keep your dog away from you to prevent transmission.

Dogs can also catch other viruses that cause stomach viruses, such as canine parvovirus or distemper. These viruses can cause similar symptoms, including vomiting, diarrhea, and lethargy.

Symptoms of a stomach virus in dogs and humans are often the same, including vomiting, diarrhea, loss of appetite, lethargy, dehydration, pain in the abdominal area, and a low-grade fever. However, dogs may also experience blood in their feces or vomit, which is not typically seen in humans.

If you suspect your dog has a stomach virus, it's crucial to see a veterinarian right away. Early diagnosis and treatment can help speed your dog's recovery. Your vet will be able to determine the underlying cause of the symptoms and provide the necessary treatment.

Here are some common symptoms of a stomach virus in dogs:

Keep in mind that blood in a human's feces is generally a sign of a more serious condition, whereas in dogs, it's a common symptom of a stomach virus.

Dogs are more likely to get sick from their owners because they share more genetic similarities with humans.

Mammals, like dogs, are more susceptible to reverse zoonosis because viruses don't have to mutate as much to cross the species barrier.

The ACE2 receptor, which the virus that causes COVID-19 binds to, exists with minor variations in all mammals, including dogs.

This means that dogs can catch the virus that causes COVID-19 from their owners.

Dogs are not the only pets that can catch viruses from humans, but they are among the most common cases of reverse zoonosis.

The swine flu, human norovirus, and tuberculosis are just a few examples of diseases that have been transmitted from humans to their dogs.

Dogs can indeed carry norovirus, a stomach virus that can be transmitted from humans to dogs. This has been shown in several studies, including one conducted at the University of Helsinki's Department of Food Hygiene and Environmental Health, which found that four out of 92 indoor dogs were infected with norovirus.

The virus can spread through oral contact with contaminated food, drink, or surfaces, or by unknowingly touching a contaminated surface and then placing your hand in your mouth. This is a good reminder to always wash your hands thoroughly after handling food or coming into contact with your dog's environment.

Norovirus can cause a range of symptoms in dogs, including vomiting, diarrhea, and abdominal tenderness or bloating. In some cases, dogs may also exhibit a low-grade fever.

If you suspect your dog has a stomach virus, it's essential to consult with your vet to determine the underlying cause. The symptoms of gastroenteritis, which is the medical term for a stomach virus, can be caused by various factors, including viruses, parasites, bacterial infections, food sensitivities, and underlying medical conditions.

Here are some common signs of a stomach virus in dogs:

Dogs can catch stomach viruses from humans, specifically noroviruses, which can cause mild clinical signs like acute watery diarrhea.

Human-to-dog transmission of noroviruses has been observed in households where children and dogs share the same premises.

Disease developed in dogs and puppies after they shared the same premises and possible direct contact with the children who had been hospitalized two weeks prior.

Genetic and phylogenetic analyses confirmed that whole genomes of canine and human noroviruses were closely related to human norovirus GII.Pe-GII.4 Sydney, suggesting a common strain is circulating in Thailand and worldwide.

Expanded surveillance for norovirus is needed to determine its status and distribution in human and dog populations.

Dog owners and veterinarians should pay more attention to norovirus infection as a potential zoonotic and reverse zoonotic disease in households, animal hospitals, and shelters.
