Can You Get Sick from Sharing Water with a Dog?

I. Introduction

The bond between humans and dogs is often deep and affectionate. Dogs are considered companions, friends, and even family members to many people around the world. As a result, it's not uncommon for dog owners to engage in the common practice of sharing water with their furry friends. However, there is a concern about potential health risks associated with this practice.

II. Understanding the Germs Dogs Carry

Dogs, like humans, can carry various types of bacteria and parasites. While many of these germs are harmless to humans, some can cause diseases. These diseases are known as zoonotic diseases because they can be transmitted between animals and humans.

Types of Bacteria and Parasites Dogs May Carry

Some common examples of bacteria and parasites that dogs may carry include:

  • Leptospirosis: This bacterial infection can be found in water contaminated by urine from infected animals.
  • Giardia: A parasite commonly found in the intestines of dogs, which can cause diarrheal illness in humans.
  • Salmonellosis: Salmonella bacteria can be present in a dog's feces, leading to gastrointestinal illness in humans.

III. Factors Influencing Disease Transmission

The transmission of zoonotic diseases from dogs to humans can be influenced by several factors:

The Dog's Health and Hygiene

A healthy and well-groomed dog is less likely to carry and transmit harmful bacteria and parasites.

The Person's Immune System and General Health

Individuals with compromised immune systems or pre-existing health conditions may be more susceptible to contracting diseases from dogs.

Environmental Factors and Cleanliness

The cleanliness of the environment, such as water sources and surfaces, can impact the risk of disease transmission.

IV. Examining the Risks

Sharing water with a dog carries certain risks that should be taken into consideration:

Contamination of Water Sources

If the water source, such as a pond or lake, is contaminated with bacteria or parasites from infected animals, both dogs and humans can be at risk.

Direct Transmission of Pathogens

Direct contact with a dog's saliva, urine, or feces can lead to the transmission of bacteria and parasites.

Routes of Infection

There are two primary routes of infection:


Drinking contaminated water or inadvertently ingesting the dog's saliva or fecal matter can introduce pathogens into the human body.

Skin Contact

Touching a dog's saliva or feces and then touching the face or mouth can also lead to infection.

V. Common Diseases and Symptoms


Leptospirosis is a bacterial infection that can be transmitted through contaminated water sources. Common symptoms in humans include high fever, muscle aches, vomiting, and jaundice. Treatment involves antibiotics, and prevention can be achieved through vaccination.


Giardia is a parasite found in dog feces and contaminated water. Symptoms in humans may include diarrhea, abdominal pain, and nausea. Treatment usually involves medication to eliminate the parasite.


Salmonellosis is caused by the Salmonella bacteria, which can be present in a dog's feces. In humans, symptoms include diarrhea, fever, and abdominal cramps. Treatment involves fluid replacement and antibiotics in severe cases.

VI. Precautions to Minimize Risks

While the risks of sharing water with a dog exist, there are several precautions that can be taken to minimize those risks:

Regular Veterinary Check-ups and Vaccinations

Keeping dogs up to date with vaccinations, including those against leptospirosis and other common diseases, can reduce the likelihood of them carrying and transmitting harmful pathogens.

Hygiene Practices for Dogs and Humans

Both dogs and humans should practice good hygiene to minimize the risk of disease transmission:

Proper Grooming and Cleanliness

Regular grooming, cleaning of water bowls, and prompt removal of dog waste can help reduce the spread of bacteria and parasites.

Handwashing and Sanitization

After interacting with dogs, particularly if there was contact with saliva, urine, or feces, thorough handwashing with soap and water or using hand sanitizer can help prevent the spread of pathogens.

Avoiding Sharing Water with Dogs

The simplest and most effective way to eliminate the risk of disease transmission is to avoid sharing water with dogs altogether.

VII. When Sharing Water Can Be Safer

In certain situations, sharing water with a dog may be considered safer:

Personal Factors to Consider

If an individual has a strong immune system and is aware of the dog's health and hygiene practices, the risks may be significantly reduced.

Filtered and Treated Water Options

Using filtered or treated water specifically designated for the dog's consumption can help minimize the risk of contamination.

VIII. Other Considerations

There are a few additional considerations regarding sharing water with dogs:

Additional Precautions for High-Risk Individuals

Individuals with compromised immune systems or pre-existing health conditions should take extra precautions and consult with their healthcare providers.

Traveling with Dogs and Water Safety

When traveling with dogs, it is essential to be mindful of the availability and safety of water sources, especially in unfamiliar environments.

Supervising Children and Dog Interactions

Children should be supervised when interacting with dogs to ensure proper hygiene practices and minimize the risk of disease transmission.

IX. Conclusion

While sharing water with a dog may seem like a harmless act, it carries potential health risks due to the transmission of bacteria and parasites. It is crucial to be aware of these risks and take necessary precautions to protect both humans and dogs. Responsible pet ownership involves regular veterinary care, good hygiene practices, and informed decision-making regarding water sharing.

By understanding the risks, practicing proper hygiene, and making informed choices, individuals can continue to enjoy the bond with their dogs while minimizing the potential for illness.


1. Can I get sick from simply being around a dog?

While the risk is generally low, certain diseases can be transmitted from dogs to humans through close contact or exposure to bodily fluids. Practicing good hygiene can help minimize this risk.

2. How often should I wash my hands after interacting with a dog?

It is recommended to wash your hands with soap and water after interacting with a dog, especially if there was contact with saliva, urine, or feces. Hand sanitizer can be used as an alternative if soap and water are not available.

3. Can I contract diseases from petting a dog?

The risk of contracting diseases from petting a healthy dog is generally low. However, practicing good hygiene, particularly handwashing, can further reduce this risk.

4. Are there any preventive measures specifically for pregnant women?

Pregnant women should consult with their healthcare providers regarding specific precautions related to interacting with dogs and potential disease transmission.

5. Is it safe to share water with my own dog?

While the risk may be lower when sharing water with your own dog, it is still advisable to avoid this practice to minimize the risk of disease transmission.

6. What if I accidentally ingest dog's saliva?

If you accidentally ingest a small amount of dog's saliva, the risk of illness is generally low. However, it is advisable to rinse your mouth and consult with a healthcare provider if you experience any unusual symptoms.

7. Can I let my dog drink from my cup or bottle?

It is not recommended to let your dog drink from your cup or bottle as it can introduce bacteria and potential pathogens into your own drink, increasing the risk of illness.

8. What should I do if I suspect my dog is sick?

If you suspect your dog is sick, it is important to consult with a veterinarian for proper diagnosis and treatment.

9. Are there any specific signs to look out for in dogs?

Signs of illness in dogs may vary depending on the specific disease. Common signs include changes in appetite, lethargy, vomiting, diarrhea, and abnormal behavior. It is best to consult with a veterinarian if you notice any concerning symptoms.

10. Can I get sick from drinking water from a dog's bowl?

Drinking water from a dog's bowl carries the risk of disease transmission if the water is contaminated with bacteria or parasites. It is advisable to avoid drinking from a dog's bowl to minimize this risk.
