Veterinary nurse issues dog drinking bowl warning

The expert said‌: “Don’t let your dogs drink out of communal water bowls. Communal water bowls are any bowls which are left outside of a person‘s house, a shop, maybe it’s at the dog park. These are basically dog bowls that multiple dogs can go and drink out of.”

She continued: “You don’t know how long that water has been sat there, you don’t know if it’s fresh, if it’s stagnant, you don’t know when the last time that bowl was washed or what it was cleaned with, and you don’t know what other animals have been drinking out of it. Don’t forget, wildlife can drink out of these bowls as well.”

She explained that dogs and other wildlife – from foxes to rodents – can “spread parasites like roundworms, tapeworm, giardia, and lung worm, because again, you’re going to get slugs that come up and go all around the edge of those bowls, which is a great way to transmit lung worm.”

Communal bowls can “also transmit infectious diseases, such as Leptospirosis” which she says is commonly spread through rodents from drinking or entering the water bowl.

While these dogs are put out with good intentions, she concluded: “I strongly advise any dog owners to not let your dogs drink out these water bowls.

“If you want to take some water with you, take a travel bowl and a bottle of water and stop occasionally to give your dog a drink. But please don’t let your dogs drink out of communal water bowl.”

Pets4Home dog bowl warning

Backing up her claims, Pets4Homes adds there are even more dangers lurking around you that you need to be aware of.

It notes: “Water bowls left uncleaned or rinsed only briefly can develop biofilm, a slimy layer where harmful bacteria such as Salmonella, Escherichia coli, and other pathogens thrive. These can provoke serious gastrointestinal upset in your dog, including vomiting and diarrhoea.

“Additionally, fungi and parasites like Giardia may contaminate water bowls or outside water sources such as puddles and lakes.

“Communal water bowls, often found outside pubs or parks, increase these risks due to multiple dogs sharing the same water. Viruses including kennel cough and canine papilloma virus may transmit through shared saliva. Studies in 2025 UK veterinary circles emphasise avoiding communal bowls to protect your dog from respiratory infections and other diseases.”
