Veterinarian Reveals Why You Shouldn’t Let Your Dog Drink From Public Water Bowls

A Texas A&M veterinarian advises pet owners to be cautious about allowing their dogs to drink from public water sources due to potential health risks.

When walking your dog in the sweltering summer heat, it might seem convenient to let them drink from a nearby public water bowl. However, these shared water sources can pose serious health risks to your pet.

Dr. Lori Teller, clinical professor at the Texas A&M School of Veterinary Medicine and Biomedical Sciences, offers guidance on the safety concerns and potential dangers linked to public hydration stations for dogs.

Lurking Below The Surface

Teller advises pet owners to evaluate the quality of public water sources before allowing their pets to drink. Even well-intentioned offerings from local businesses or neighbors could contain hidden contaminants.

“This is of particular concern if the bowl is not cleaned regularly or if the water is left standing for extended periods of time,” Teller said. “Stagnant water can retain environmental contaminants, such as plant material, parasites, toxins, mold, and more. Dogs that have stepped in fecal matter and then played in the bowl could leave parasites and bacteria in the water.”

Teller said diseases that can be transmitted from public water bowls include:

• Kennel cough: a respiratory infection that leads to a gag-like cough, lack of appetite, and labored breathing;
• Canine papilloma: a virus spread through saliva that causes warts in and around the mouth;
• Salmonella: an infection that causes bloody diarrhea, fever, and vomiting;
• Giardia: a parasite leading to weight loss, diarrhea, and vomiting;
• E. coli: a bacteria that causes dehydration, diarrhea, and lack of appetite; and
• Leptospirosis: a bacterial disease commonly spread by rodent urination that can lead to kidney and liver disease, or even death, in dogs.

Best Judgment

Hydration awareness can help take away the risk of water contamination, especially if an owner considers their furry friend’s water needs before leaving the house.

“Ideally, owners would carry a collapsible, portable bowl and some fresh water with them to give to their dog,” Teller said. “Alternatively, they could stop at a restaurant or convenience store and request a cup of water for their dog.”

While a potential risk will always be present in publicly available water bowls, Teller believes there are certain situations when these risks are worth taking.

“If your dog is hot and thirsty and at risk of dehydration, then that may take precedence over avoiding the water in the bowl,” Teller said.

Two For One

In addition to considering the safety concerns associated with publicly shared water bowls, Teller recommends that owners also consider the risks of multiple pets sharing one food bowl in the same home. Sharing is caring in most cases, but, according to Teller, an owner may not be caring by making dinnertime a lesson in sharing.

“Often, dogs may need different portions of food, and in many cases, one dog may need a diet change due to a medical condition; that can be much more challenging to manage if the dogs share a bowl,” Teller said. “Or, one dog may prevent another from eating out of the bowl.”

On the other hand, having the same water bowl in a household of multiple pets does not bring about the same problems as food bowl sharing.

“In most cases, dogs living in the same house will be exposed to similar infectious agents, so sharing a water bowl will not have a tremendous impact on that,” Teller said. “It is still important that water bowls (and food bowls) be washed with soap and hot water on a regular basis.”

Deciding if a public water bowl is safe for your panting pup is a case-by-case decision for an owner. Teller insists that if it looks like pond water, a dog should not drink from it. When in doubt, it is always better to be cautious with the possibility of contaminated water, as owners should not gamble with the health of their cherished pet.
