Dog saliva is antibacterial, but it probably won’t heal wounds.
Dogs often lick their wounds in order to clean them. There may be healing properties in a dog’s saliva, and this may be another reason that they lick their wounds.
Certain proteins in dog saliva called histatins can defend against infection, and research has shown that there are other beneficial chemicals in a dog’s saliva that can help protect cuts from infection.
There is evidence that suggests that wounds licked by dogs heal twice as fast as wounds that were not licked. In one 2018 study, researchers discovered that canine saliva contains various proteins, antimicrobial enzymes, and peptides that make holes in bacterial cell membranes.2
Unfortunately, not all wounds will heal when licked. Moisture and inflammation from licking, and in some cases, the bacteria that lives in the saliva, can slow healing or even make the infection worse.
This is why veterinary visits are recommended for even superficial wounds. Often, your veterinarian will recommend a collar or a bandage to keep your dog from licking their wounds and causing more trauma to the already inflamed area.
Both dogs and humans are equally susceptible to dental disease and benefit from good oral hygiene practices to keep their mouths clean and healthy. Regular brushing and dental cleanings help humans and dogs keep harmful bacteria, like the kind that cause periodontal disease, in check and are an important part of a daily routine.

In fact, dogs have more than 600 different types of bacteria in their mouths, which is a similar number to the 615 and counting types of bacteria Harvard researchers have found in human mouths. These bacteria can also be joined by other bacteria that we (humans and dogs) pick up from our environments, adding to the mix.
Does this mean that you should have your dog lick your wounds, or that you should lick your own wounds?
Comparing a dog’s mouth to a human’s mouth is “like comparing apples and oranges,” according to Colin Harvey, a professor at the University of Pennsylvania’s School of Veterinary Medicine and the executive secretary at the American Veterinary Dental College.
The most serious signs and symptoms of Capnocytophaga infection are those of septic shock. Symptom onset typically begins 3 to 5 days after an animal bite or contact, including sepsis, organ failure and meningitis. It is very important to identify and treat Capnocytophaga infections as quickly as possible because approximately three out of 10 people who get infected with severe Capnocytophaga die and infections can result in death within 24 to 72 hours of symptom onset. People who are asplenic or have weakened immune systems are at greatest risk for serious infections. Capnocytophaga infections are treated with antibiotics. People should consult with their health care provider to determine the most appropriate treatment.
Capnocytophaga infections are not nationally reportable, so there is no national estimate of the number of infections that occur every year. Additionally, Capnocytophaga can be easily diagnosed by routine microbiology laboratory tests, so many cases of the disease are likely diagnosed and treated by health care providers without ever being reported to CDC. MicrobeNet, CDC’s online reference library, has received reports of 12 positive cases in the past year. These are likely only the most severe cases or those in which diagnosis was complicated for some reason. However, these do not include the most recent cases that have been reported by the media.
In June, a man in West Bend, Wisconsin, had both hands and lower legs amputated after being infected with the bacterium Capnocytophaga canimorsus, possibly through contact with a dog, according to the Milwaukee Journal Sentinel. Two other recent cases were reported in Wisconsin, according to the paper: a boy aged 3 years who had his fingers and toes amputated after being exposed to C. canimorsus, and a woman who was bitten by her dog and developed rapidly progressing influenza-like symptoms that resulted in her death.
Many dogs and cats have Capnocytophaga in their mouths (normal oral flora), and it does not cause them illness. Animals can be tested, but a negative result may not mean the animal will always be negative, and the same is true for a positive result. Although animals could be given medicine to kill the bacteria in the short term, they can still get the bacteria again through contact with other animals. It is important that people with weakened immune systems take this into consideration when they are considering getting a new pet. However, it is still important to emphasize that most contact with dogs and cats does not result in a Capnocytophaga infection or any illness. CDC’s Healthy Pets Healthy People [webpage] has tips for these high-risk groups on how to have safer contact with pets: https://www.cdc.gov/healthypets/index.html.
Typically, Capnocytophaga does not cause disease in humans, and most human contact with dogs and cats — even through bites — does not result in illness. However, in rare cases, people can develop illness from this infection. This is most common in people who are asplenic, have a history of excessive alcohol use or have a weakened immune system for other reasons (for example, people who have cancer, HIV, liver disease, or take certain medications like steroids that make it more difficult to fight off infections). In the rare cases when illness disease develops, it can be serious and rapidly fatal without antibiotic treatment. Most people who become ill will begin showing symptoms within 3 to 5 days, but this can range anywhere from 1 day to 2 weeks. Signs and symptoms can include blisters around the bite wound within hours; redness, swelling, draining pus or pain at the bite wound; fever; diarrhea and/or stomach pain; vomiting; headache and/or confusion; and muscle or joint pain. Approximately three out of 10 people infected with Capnocytophaga die, and some infections can lead to death in as little as 24 to 72 hours after symptoms start. If someone does develop clinical signs consistent with Capnocytophaga infection after a dog or cat bite or contact with their saliva, they should seek medical care immediately. Click to enlarge .
Verify: Can dog saliva cause an infection?
Most of the time, dogs don’t know they transmit germs to their owners. They lick their faces because it’s fun and it feels good. We all know that dog saliva has microbes in it. But did you know that these microbes can be harmful to humans? That’s right – several pet diseases are transmitted to humans through infected saliva. So, what diseases can you get from dog saliva? Read on to learn everything you need to know about the illnesses caused by dog saliva and how to protect yourself from them.
Dog diseases that transfer to humans are known as zoonotic disease. These include viral and bacterial infections and parasitic infestations. Dog saliva is a source of bacteria that can cause infections and diseases. Some of these germs can also transfer to humans through direct contact, air, or skin-to-skin contact.
1)Rabies The biggest concern about dog saliva transferring germs to humans is rabies. Rabies is the zoonotic dog virus that affects the nervous system of mammals and can cause a fatal disease if untreated. The virus is spread through bites or scratches from an infected animal, usually a dog or cat. Rabies is transmitted from animals to people. Dogs are the primary carriers of this virus, and it is the cause of common dog deaths. That is why dog owners must ensure that their pets are vaccinated yearly against rabies. The virus attacks the brain and central nervous system, causing symptoms such as fever, headache, tiredness, irritability, and confusion. Rabies is fatal if left untreated. The best way to protect yourself and your family from rabies are to avoid contact with animals that are known virus carriers. Dogs without shots around babies are unsafe. It includes stray dogs, wild animals, rodents, and bats. If you have been exposed to a potentially rabid animal, call your doctor immediately for treatment options.
2)Pasteurella Pasteurella is a gram-negative organism often found in dogs’ respiratory tracts. It is a bacterium that can cause respiratory disease in dogs, cats, and humans. It causes. Dog nose disease has been linked to various canine diseases, including bacteremia and septicemia. However, it can also be transmitted from dog to human. They live in the oral cavity, respiratory tract, and gastrointestinal tract of animals. Symptoms of this animal disease are coughing, distress, and abnormal breathing. Your dog’s oral infection with Pasteurella could spread to you via saliva or vomit. A person can be infected by inhaling contaminated dust or droplets of saliva or nasal discharge from an infected animal.3)Salmonella Salmonella is one of the medical conditions of dogs that can transmit to humans. The bacteria can cause an infection in the small intestine of humans, causing diarrhea, fever, and abdominal cramps. The transmission of salmonella between humans and dogs occurs when a dog licks its owner’s face or hands. Salmonella is also found in the stool and vomit of infected dogs. Salmonella infections are rare in healthy adults; however, children younger than five years old and older adults are at greater risk for developing symptoms such as diarrhea, fever, and abdominal cramps. There are several ways to prevent the transmission of salmonella from your pet to you: You can reduce your risk of getting salmonella by washing your hands thoroughly before touching any food or petting your dog or cat. If you develop diarrhea after having contact with an infected animal, you must see a doctor as soon as possible to get proper treatment.4)Brucellosis Brucellosis is a disease caused by the bacterium Brucella, which can be found in dogs and other animals. It can also be transmitted to humans through contaminated feed, water, or contact with infected animals. The bacteria in the dog’s mouth can also be transmitted to humans through respiratory secretions or contaminated objects like food and clothing if a person is bitten or scratched by an infected dog. You should also avoid kissing your pet and making contact with its saliva or mucus during grooming sessions.5)Campylobacter Campylobacter is a prevalent bacterial disease that is transmitted from dogs to humans. This disease can also transmit by contaminated food or water. In humans, campylobacteriosis usually begins with non-specific symptoms such as fever, diarrhea, and abdominal cramps lasting from a few days to more than two weeks. The disease is often associated with gastroenteritis (diarrhea) and vomiting. More severe complications may occur in immunocompromised patients.6)Coxiella burnetii As it is known, Coxiella burnetii is a pathogen that causes Q fever. It can be transmitted from dogs to humans. As dog saliva contains many infectious agents, washing your hands well with soap and water after petting dogs and cats is essential. Ticks can also transmit the disease from dog to human. Q fever is an infection that mainly affects the respiratory tract and nervous system. It can cause pneumonia, meningitis, and encephalitis in humans who have not been vaccinated against it. You can prevent Q fever by avoiding contact with sick animals and their saliva. The most common symptoms of Q fever include fever, fatigue, nausea, diarrhea, and chills. If exposed to this disease, you should seek medical attention immediately so your doctor can prescribe antibiotics to treat any symptoms you may have and prevent complications from developing further down the line.
7)Capnocytophaga The Capnocytophaga bacterium is a Gram-negative bacterium in the oral cavity of humans and animals. The bacteria are the leading cause of sepsis in dogs and cats. Capnocytophaga can be transmitted from dog saliva to humans. It causes an infection in humans leading to fever and headache. Capnocytophaga infections are prevented through good oral hygiene and regular checkups at the vet clinic.
