Are you wondering how often you should wash your dog's water bowl? A vet has warned about the risks of improper cleaning — and shared how often it should really be done.

"I advise that owners wash their dog's water bowl daily," says Emma Chandley, a vet working with pet insurance brand Petgevity. "Rinse thoroughly in hot soapy water – scrubbing inside and out for around 30 seconds – ensuring all residue is gone. Leave to air dry or wipe with a clean towel."

Stagnant water bowls can harbour bacteria and other environmental contaminants, posing a risk to pets and, in some cases, leading to Chronic Kidney Disease (CKD). Stainless steel water bowls are the safest option, as plastic bowls can absorb odours and become breeding grounds for bacteria.

If you rinse the bowl without proper scrubbing, a slimy bacterial layer called 'biofilm' quickly builds up inside, posing a risk to your dog's health.

"In most healthy dogs, this will not lead to kidney damage, but repeated exposure to harmful bacteria could increase the risk of gastrointestinal illness or, in rare cases, ascending infections. Severe kidney infections, if left untreated, have the potential to cause longer-term renal damage.

"Regular cleaning of water bowls is therefore a sensible hygiene practice. While an unwashed bowl does not directly cause CKD, poor hygiene can contribute to health risks that may indirectly affect overall wellbeing."

If you think your dog may be unwell from a contaminated water bowl, always head to your local vet.

The signs of CKD to look out for include: "Increased thirst and urination are common but can develop gradually, so they may be overlooked. Some dogs lose weight slowly, are quieter than usual or seem slightly nauseous, which might present as lip licking or reduced appetite.

"As the disease advances, vomiting, lethargy, muscle loss and poor coat quality may become more obvious."
