Dog Licks Toilet Water? Here’s How to Stop It

Why Dogs Drink Toilet Water

Dogs may be drawn to toilet water because it’s cool, fresh, and often contains a mix of water and chemicals that some dogs find appealing. In one case, a dog named Mazel drank from the toilet despite closed doors and lids being used—she simply pushed the door open with her nose. This shows that even simple barriers may not be enough if the behavior is driven by strong preference or need.

Some dogs, like Mighty Victor, prefer the cool tile floor of bathrooms, especially in warm weather. This environmental preference can lead to prolonged time in the bathroom, increasing the chance of drinking from the toilet. The behavior isn’t always about taste—it can be about temperature, texture, or routine.

Address the Root Cause First

Before applying punishment or barriers, ask: Why is your dog drinking toilet water? In one case, a dog’s excessive drinking was linked to steroid medication for skin issues. Once the underlying medical cause was identified, the behavior decreased. This highlights the importance of checking with a vet if your dog suddenly starts drinking more water than usual.

If your dog is thirsty, the toilet may simply be the most accessible source. Providing a fresh, clean water bowl nearby can redirect this behavior. Make sure the water is changed frequently and the bowl is washed daily—dogs are sensitive to taste and bacteria buildup, which can make water unappealing.

Use Management to Prevent Access

Even if you solve the root cause, management is key to stopping the behavior. If your dog keeps getting to the toilet, use physical barriers. Options include: - Closing bathroom doors with secure latches. - Using covered garbage cans or cabinets to block access to tempting areas. - Placing boxes or upside-down chairs on furniture to prevent access.

For toilet access, consider using a lid that locks securely—though caution is needed. One owner tried locking the toilet with a key, but forgot it during an emergency. This shows that while locks can work, they must be reliable and accessible.

Make Fresh Water More Appealing

Dogs have preferences—some avoid water that’s been “polluted” by other dogs, while others love even the dirtiest water. To encourage drinking from their bowl, keep it clean and refill it often. Use cool, fresh water and wash the bowl daily with soap and hot water to prevent bacterial growth.

The way dogs drink—using their tongues to scoop water—creates drool and mess, which can quickly dirty the bowl. This means even clean water becomes unappealing fast. Refreshing the water several times a day helps keep it fresh and more tempting than toilet water.

Train and Redirect Behavior

Once access is managed and water is fresh, train your dog to go to their bowl instead. Reward them when they drink from it. Use positive reinforcement like treats or praise to build the habit.

If your dog is already used to drinking from the toilet, redirect their attention with a command like “Leave it” or “Off,” practiced in training sessions. However, training alone is not enough—management must support it. A tired dog is less likely to seek out forbidden water, so ensure your dog gets enough exercise.
