Dog Licked My Food. Can I Still Eat It?


When you think of sharing, your dog might be the last being that comes to mind, right? Sure, you’ll gladly share a playful romp, a sunny afternoon walk, or even the warmth of your bed. But how about sharing your food… especially if it’s been “pre-tasted” by your furry friend? We’ve all been there: in the middle of enjoying a snack, your pup sneaks up, gives your food a quick lick, and walks away, leaving you with the quandary – to eat or not to eat?

In most cases, you can still eat the food your dog has licked without any problems. However, there are still potential health risks to be aware of. The main concern lies in the possible transfer of bacteria and parasites from your dog’s mouth to your food, which could potentially cause infections.

Moreover, the degree of risk is not the same for everyone. It can vary based on factors such as the health status of your dog, the type of food in question, and your health condition. Understanding these nuances will help you make an informed decision next time your canine companion decides to test your meal.

What Happens If I Eat Something My Dog Licked?

Living with a dog is a joyful and rewarding experience. But the joys of pet ownership can come with some unexpected twists, like finding your four-legged friend sneaking a lick of your food when you’re not looking. In general, eating something your dog has licked doesn’t pose a significant health risk, but there are potential implications that are worth noting.

Gastrointestinal illness

Gastrointestinal illnesses can be one of the more immediate implications when consuming food that your dog has licked. Dogs are naturally curious creatures that use their mouths to interact with their environment. This exploration can lead them to ingest various types of bacteria and parasites which can then be transferred to your food through their saliva.

Some common bacteria that dogs might carry in their mouths include Salmonella, Campylobacter, and E. coli. These bacteria, when ingested by humans, can lead to gastrointestinal illnesses characterized by symptoms such as nausea, vomiting, abdominal cramps, and diarrhea.

In addition to bacteria, dogs can also be hosts to a variety of parasites. Some of these, like Giardia and Cryptosporidium, can survive in the environment for long periods and may be picked up by dogs during their explorations. If transferred to humans, these parasites can cause giardiasis or cryptosporidiosis respectively, leading to symptoms such as diarrhea, gas, abdominal discomfort, nausea, and vomiting.

The impact of these illnesses can range from mild, causing a temporary upset, to more severe cases requiring medical intervention, especially in individuals with compromised immune systems. Preventative measures such as regular deworming and maintaining good hygiene can minimize the risk of your dog picking up these harmful agents.

Periodontal Gum Disease

The oral cavity of dogs, particularly those not receiving regular dental care, can harbor bacteria that cause periodontal disease. When a dog licks your food, these bacteria can be transferred and potentially lead to gum infections in humans. Symptoms of gum infections may include redness, swelling, bleeding, or tenderness in the gums and even bad breath. If left untreated, this can progress to more serious conditions such as periodontitis, potentially leading to tooth loss.

Allergic Reaction

Although relatively rare, some people may be allergic to certain proteins found in dog saliva. If you are allergic and consume food your dog has licked, this may trigger an allergic reaction. Symptoms can range from mild, such as itching or swelling around the mouth, face, or throat, to severe cases of hives, difficulty breathing, or even anaphylaxis, a potentially life-threatening condition. In case of a severe allergic reaction, it is crucial to seek immediate medical attention.

Skin Problems

Dogs can be carriers of this fungus, and it can be present in their saliva. When your dog licks your food, there’s a potential risk of this fungus being transferred.

If consumed, you might not necessarily get a ringworm infection in your mouth or throat, as the fungus typically affects the skin, scalp, or nails. However, if you touch the licked food and then touch other parts of your body, particularly if you have cuts or abrasions, you might risk a ringworm infection.

Ringworm infections are characterized by a red, circular rash that’s often itchy. The rash might also have a more clear or normal-looking center, which gives it a ring-like appearance, hence the name “ringworm.” Besides being itchy, the affected area might also be slightly raised or scaly and can cause discomfort.

While ringworm infections are typically not serious and can be treated effectively with antifungal medication, they can be bothersome due to their itchy nature and can be spread to other parts of the body or other individuals. Therefore, it’s important to seek treatment if you suspect you have a ringworm infection.

Common Infections You Can Get From Eating Food Your Dog Licked

When dogs lick food meant for human consumption, they can transfer bacteria, parasites, and fungi that could potentially lead to various infections if ingested. Here are some common ones:


Dogs can be asymptomatic carriers of Salmonella, a bacterium typically associated with foodborne illnesses. If this bacterium is present in your dog’s saliva and gets transferred to your food, it can cause salmonellosis in humans, leading to symptoms such as diarrhea, fever, and abdominal cramps.


Found in the mouths of many healthy dogs, Pasteurella can cause skin and soft tissue infections in humans, typically following an animal bite or scratch. If this bacterium is present in your dog’s saliva and makes its way into your mouth, it can theoretically lead to infection, characterized by redness, pain, and swelling at the site.

E. Coli

Escherichia coli, or E. coli, is another bacterium that dogs can carry in their intestines without showing any signs of illness. If transferred to humans through food, certain strains of E. coli can cause illnesses ranging from minor gastrointestinal upset to severe food poisoning, with symptoms like severe stomach cramps, diarrhea, and vomiting.


Campylobacteriosis, caused by the Campylobacter bacterium, is one of the most common causes of diarrheal illness in humans. Dogs can carry these bacteria and show no signs of illness. In humans, it can cause diarrhea, cramping, abdominal pain, and fever.

Clostridium difficile

Clostridium difficile, also known as C. diff, can be present in the intestines of both dogs and humans. In humans, overgrowth of this bacterium can lead to severe diarrhea and more serious intestinal conditions such as inflammation of the colon.


Hookworms are intestinal parasites that can cause infection if their eggs or larvae are ingested. Dogs can pass hookworm eggs in their feces, which can then contaminate environments. If accidentally consumed by humans, hookworms can cause anemia, abdominal pain, and in severe cases, malnutrition.


Roundworms are common parasites in dogs, and their eggs can be passed in dog feces. If ingested by humans, they can cause a disease known as toxocariasis, with symptoms ranging from mild (like cough or abdominal pain) to severe (including vision loss or organ damage).


Giardia is a microscopic parasite that can live in the intestines of dogs and humans. If a dog carrying Giardia licks your food and you consume it, you can get infected, leading to an illness called giardiasis, which causes diarrhea, stomach cramps, and nausea.


Dogs infected with ringworm can carry the fungus in their saliva. If transferred to humans, it can cause a skin infection, characterized by a red, itchy, circular rash.

While the risk of contracting these infections is generally low, it’s always wise to discourage your pet from licking your food. Ensuring your pet receives regular veterinary care, including deworming and vaccinations, can further mitigate these risks.

What Should I Do If I Ate Food My Dog Licked?

Discovering that you’ve eaten food your dog has licked can be a surprising and potentially unsettling experience. Here are some steps to consider if you find yourself in such a situation.

Don’t Panic

Firstly, don’t panic. In most cases, consuming food that your dog has licked won’t cause any serious health issues. Dogs and humans have cohabited for thousands of years, and our bodies have adapted to handle many of the common bacteria and microorganisms found in a dog’s mouth.

Assess Your Dog’s Health

The risk of getting sick from eating something your dog licked is significantly higher if your dog is currently unwell, especially if they have a bacterial or parasitic infection. If your dog is sick and has been diagnosed with a condition that can be transferred to humans, it’s essential to practice good hygiene and avoid sharing food.

Are you keeping up with your dog’s deworming schedule and vaccinations? Regular veterinary care plays a critical role in keeping your pet—and by extension, you—healthy. You should also ensure good hygiene when taking care of your pet as this can play a big role in determining whether you are likely to be infected sharing food with your dog.

Concerns For Special Populations

Certain populations are at greater risk of complications from zoonotic diseases—those that can jump from animals to humans. These include young children, the elderly, pregnant women, and individuals with compromised immune systems. These groups should be particularly careful about sharing food with pets.

Seek Medical Attention if Necessary

If you’ve eaten food your dog licked and start experiencing symptoms like diarrhea, vomiting, skin rashes, or other unusual signs, it’s important to seek medical advice. While it’s unlikely to be a severe issue, it’s always better to err on the side of caution.

In general, while the bond between you and your pet is precious, it’s a good practice not to share your food with them. Not only does this reduce the risk of potential infections, but it also discourages begging behavior and ensures your pet sticks to its nutritionally balanced diet.

Regular hand washing, especially before meals, can also go a long way in preventing the spread of bacteria and other microorganisms from your dog to you. By maintaining these healthy habits, you can enjoy the companionship of your pet while ensuring that both of you stay healthy.

Why Does My Dog Lick His Bowl?

Why Does My Dog Make Attempts To Eat My Food?

Ever wonder why your canine companion seems to have an insatiable interest in your food? There are several reasons why dogs may be inclined to partake in our meals, even when they have their own.

Your Food Smells and Tastes Better

Just like humans, dogs are drawn to foods that are aromatic and flavorful. Canine noses are vastly superior to ours, with up to 300 million olfactory receptors compared to our six million. This heightened sense of smell makes our cooking aromas incredibly enticing to dogs. In comparison, their regular dog food might seem bland and less appealing. Plus, human food often has a wider variety of textures and flavors, making it even more attractive.

Your Doggo is Spoiled

Yes, even dogs can be spoiled! If you’ve been sharing your food with your dog regularly, you may have inadvertently conditioned them to expect it. Once dogs learn that begging or showing interest in your food results in tasty treats, they’re likely to continue the behavior.

Boredom or Anxiety

Sometimes, your dog’s interest in your food might not be about hunger at all. Dogs can experience boredom and anxiety just like humans do. In these situations, they may turn to food as a source of comfort or distraction. If your dog is showing excessive interest in your food and is also displaying other signs of stress or boredom, it might be time to consider additional mental and physical stimulation.


If dogs are hungry, it can trigger their interest in taking a bite of your yummy food. This could be the case if their meals aren’t satisfying their dietary needs. All dogs are different and some may require more food than others based on their age, size, breed, and activity level. If your dog is always hungry and interested in your food, it might be worth talking to your vet about adjusting their diet.


Dogs are naturally curious creatures. They use their mouths to explore the world, and this includes tasting various foods. Your dog might just be interested in sampling something new and different. While a small nibble of safe, dog-friendly foods won’t harm them, it’s important to keep certain foods that are toxic to dogs, like chocolate, grapes, and onions, out of their reach.

Remember, while it’s often harmless to occasionally share a safe treat with your dog, regularly feeding them human food can lead to nutritional imbalances, obesity, and other health problems. It can also reinforce bad habits and lead to begging behavior. Instead, try reinforcing good behavior with dog-specific treats and maintaining a balanced diet appropriate for their specific needs.

How To Stop Dogs From Eating Human Food

Just as it’s important to understand why dogs may try to eat human food, it’s equally essential to know how to prevent this behavior. Here are some strategies to ensure your furry friend sticks to their meals and maintains a healthy diet.

Have A Fixed Feeding Routine

Dogs thrive on routine and consistency. Having a fixed feeding schedule can help manage your dog’s hunger and anticipation of meals. This also helps regulate their digestive system and decreases the likelihood of them begging for your food.

Sufficient And High-Quality Meals

Make sure you’re providing your dog with enough food that’s of good quality. Their diet should be nutritionally complete and balanced, containing the right mix of proteins, carbohydrates, and fats suitable for their age, breed, and health status. High-quality dog food is designed to be tasty and appealing to dogs, reducing their desire for human food.

Don’t Spoil Them With Human Foods or Table Scraps

While it might be tempting to share your dinner with those puppy dog eyes looking up at you, resist the urge. Regularly giving your dog human food or table scraps can condition them to expect it and can contribute to unhealthy weight gain and nutritional imbalances. Moreover, certain human foods can be harmful or even toxic to dogs.

Positive Reinforcement

Use positive reinforcement to train your dog not to beg for human food. This could involve praising them or giving them a dog-friendly treat when they stay away from your food. Conversely, if they beg or try to snatch food, ignore the behavior rather than give in or tell them to “leave it“. With consistent reinforcement, your dog will begin to understand that begging doesn’t yield rewards.

Shower Them With Attention

Sometimes, dogs may beg for human food simply to get your attention. By ensuring your dog gets plenty of love, affection, and mental and physical stimulation throughout the day, they’ll be less likely to seek attention during your meal times.

Implementing these strategies can not only help stop your dog from eating human food but can also contribute to their overall health and well-being. Remember, while it can be a process requiring patience and consistency, the effort you put into training now can prevent potential health issues and behavior problems in the future

I Accidentally Drank My Dog’s Water

Mistakenly drinking from your dog’s water bowl might occur more often than you think, but most times, it’s not cause for alarm.

Many bacteria found in a dog’s water bowl are usually transferred while drinking and are opportunistic bacteria like E. coli, and Salmonella, and Parasites like Giardia, Hookworms, and Roundworms. While these organisms may be harmless, they can potentially cause illness when there is a breach in their mechanical barrier or when the host’s resistance is compromised.

If your dog is healthy and their bowl is cleaned daily, the risk of falling sick is relatively low. If you start feeling unwell, such as experiencing diarrhea, vomiting, or fever, reach out to a healthcare provider, as there’s a small possibility of zoonotic transmission (infectious diseases transmitted from animals to humans).

To prevent future mix-ups, keep your water and your pet’s water in separate areas and ensure your pet’s dish is cleaned regularly.

What happens when dog saliva gets in your mouth

There is a popular belief that dogs’ saliva is cleaner than that of humans. However, this is untrue as they contain a multitude of bacteria. Some of these bacteria are specific to the canine oral environment and typically do not pose a risk to humans. However, in certain scenarios, some zoonotic pathogens can be present in a dog’s saliva.

Zoonotic diseases that could be present in dog saliva include Pasteurella, E. Coli, Salmonella, Giardia, Hookworms, Roundworms, and more. If dog saliva containing these pathogens enters the human body, it could potentially lead to infections. For instance, Pasteurella multocida, a common bacterium in the mouths of dogs, can cause a range of infections in humans, from skin and soft tissue infections to more severe conditions such as septicemia in rare cases.

Is it safe to share food with a dog?

Don’t be tempted by those puppy-dog eyes. Sharing your meals with your furry friend is generally not recommended. The primary concern is the potential transmission of various opportunistic bacteria and parasites, in your dog’s saliva. Additionally, many foods that humans consume can be toxic to dogs, such as chocolate, grapes, onions, garlic, and certain artificial sweeteners like xylitol.

Moreover, allowing your dog to taste your food can lead to the development of undesirable behaviors in dogs. Dogs may develop a habit of begging for food during human meal times, which can be disruptive and can lead to unhealthy dietary practices for the dog. Dogs have specific nutritional needs, and their diet should be tailored to those needs.

Furthermore, dogs can be allergic to certain types of human food, or they might have a sensitive stomach that doesn’t react well to sudden changes in diet. Some foods can also be a choking hazard for dogs, especially small ones

Final Thoughts

It’s clear that there is no one-size-fits-all answer to the question, “Can I still eat my food if my dog has licked it?” The factors influencing your decision range from the health status of your dog to the nature of the food they’ve licked, as well as your immune system health.

While there’s a low risk of contracting serious diseases from a healthy pet in a clean household, it’s important to bear in mind that pets’ mouths are not necessarily cleaner than ours and they can still transmit bacteria and parasites that could potentially cause illnesses. As such, if you have a compromised immune system or the food is something that can easily harbor bacteria, it might be best to err on the side of caution and not consume the food.

Moreover, developing a habit of allowing your dog to lick your food could lead to some unwanted behavioral problems. To prevent any such issues, it’s advisable to encourage good eating habits in your dog from an early stage.
