Yes, you can get sick from kissing your dog as their saliva can carry bacteria (like Capnocytophaga, Pasteurella, Salmonella, E. coli) and parasites that cause zoonotic infections, leading to symptoms like fever, diarrhea, headaches, or more severe issues, especially for those with weakened immune systems, young children, or the elderly. While most healthy people won't get seriously ill, the risk exists, so it's best to avoid kissing your dog on the mouth and instead offer hugs or pats, and practice good hygiene like handwashing after contact.
Yes, your dog has bacteria in their mouth. Pastuerella – lives in the mouths of cats and dogs that can cause skin, lymph node and, sometimes, more severe infections.
A: Dogs and cats may lick humans to show empathy or affection — or simply to get your attention. For healthy adults, the risk of illness after being licked by a pet that receives regular veterinary care is negligible. But when dogs and cats lick people with weak immune systems, serious infections can follow.
Capnocytophaga bacteria are commonly found in the mouths of dogs and cats. Capnocytophaga germs can make people sick if they're bitten or the dog or cat's saliva (spit) gets into an open wound or sore. Most people who have contact with a dog or cat do not become sick.
You can absolutely catch viruses from your pets, including dogs and cats. And it isn't just from getting pet kisses. If you're physically close with your dog or cat – like snuggling on the couch together or sleeping in the same room, you're exposed to their viruses even without the saliva directly on your face.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
But illnesses common among house pets — such as distemper, canine parvovirus, and heartworms — can't spread to people. But some types of bacteria, viruses, parasites, and fungi that pets can carry can make people sick though a bite or scratch, or if someone has contact with an animal's waste, saliva, or dander.
While healthy adults will almost certainly survive being exposed to the viruses or bacteria in their dogs' mouths, there is a non-zero risk of gastrointestinal illness and oral diseases from puppy kisses. Certain parasites like giardia, roundworms, and hookworms can also be transmitted through licks.
Capnocytophaga canimorsus is a bacterium transmitted through the saliva of dogs. An infection can cause severe sepsis with acral necrosis and is potentially fatal. Here, we report the case of a 41‐year‐old man who was infected through a wound that was licked by his dog.
Can You Get Infections and Diseases From Dog Saliva? The chance of germs being transmitted to humans through a dog's saliva is extremely minimal. However, it does still have a chance of happening. Through their saliva, dogs can spread bacterial and viral illnesses.
To say "I love you" in dog language, use soft eye contact, raise your eyebrows, give gentle massages (especially ears), lean into them, and engage in play or shared activities like walks, which build trust and affection through shared experiences and physical connection, releasing oxytocin for both of you.
Dogs say "sorry" through submissive body language like tucking their tail, lowering their head, making "puppy eyes," licking, and rolling onto their backs to show they're not a threat, which are appeasement signals to diffuse tension after a conflict or misbehavior, often combined with whining or approaching and retreating. They recognize when their human (or another dog) is upset and use these signs to seek forgiveness, though it's more about reducing stress than human-like guilt.
You can get hookworms and other parasites from dog saliva.
Most intestinal parasites are transmitted through a fecal-to-oral route and more easily if you have a wound in your mouth. These parasites include Giardia, hookworms, and roundworms.
The fact is that dogs and humans have comparable amounts of bacteria in their mouths, and the chances of getting sick from your dog's kisses are low. Still, the CDC warns of the possibility of transferring diseases mouth-to-mouth between pets and their human parents (like Giardia and staph infections).
Dogs' saliva poses a very low risk of transmitting germs to humans, but there is still a possibility. Dogs can spread bacterial and viral diseases through their saliva. These illnesses can be transmitted if a dog bites you or if their saliva enters your nose, mouth, or eyes.
That's why one expert, Dr. Leni K. Kaplan, of Cornell University's College of Veterinary Medicine, told the Times that pet owners shouldn't let their dog kiss a person's mouth, nose, and eyes, through which certain pathogens, including salmonella and E. coli, can be transmitted.
Most of the viral and bacterial infections are transmitted from dogs to humans by dog bite; however, other infections caused by protozoa have a fecal oral transmission.
While there is some overlap in the types of bacteria between species, a dog's mouth contains a number of dental bacteria that you will not find in yours. A dog's mouth contains approximately 600 different species of germs, as opposed to the 615, and counting, varieties in the human mouth.
It's not likely to spread after later symptoms such as rashes and joint pain appear. Most often, it's safe to go back to work or school once the rash shows up. Other types of parvoviruses exist, but they only infect animals such as cats and dogs. So you can't get infected from a sick pet.
Why Not to Kiss? Dr. Neilanjan Nandi, has stated that a dog's mouth is host to “an enormous oral microbiome of bacteria, viruses and yeast.” The term “zoonotic” is frequently used to describe the bacteria that reside in your dog's mouth that is able to be passed on to humans and cause disease.
While dogs may not understand kisses in the way humans do, they can learn to associate them with positive emotions. Each dog is different, so it is essential to read their body language and respect their preferences to ensure they feel comfortable and loved.
You shouldn't do anything. Dogs have no concept of appropriate and inappropriate. They just lick. If you're worried about bacteria, a shower will take care of that, but you'll be fine.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home).

Now for the good news: although it's possible to catch a zoonotic disease that's been bothering your pup, it's not likely. That being said, your chance of contracting a zoonotic illness does increase if you have a compromised immune system due to a pre-existing disease or medical condition.
Feral swine are known to carry at least 30 viral and bacterial diseases and nearly 40 parasites that can be transmitted to humans, pets, livestock, and other wildlife.
