Why Does My Dog Drink From the Toilet? How to Stop It

Why Dogs Drink From Toilets

Dogs may drink from toilets for several reasons. In one case, a Great Pyrenees puppy named Mighty Victor drank excessively from the toilet because he had been eating salty pretzels, which made him thirsty. The salty snacks caused him to guzzle water, leading him to seek out the nearest source—often the toilet. Similarly, dogs may prefer the cool, fresh water in a toilet bowl over stagnant water in their own bowl, especially in warm environments.

Another dog, Mazel, drank from the toilet because it was easily accessible and the water was cool. Even when owners tried simple fixes like closing the bathroom door or keeping the lid down, the dog could still push the door open with her nose and access the water.

Address the Root Cause First

Before trying to stop the behavior, it’s important to understand why your dog is doing it. If your dog is drinking more than usual, check their diet. Salty foods like pretzels or certain treats can increase thirst. Removing these items may solve the problem entirely.

In some cases, dogs seek out toilets because they’re hot or uncomfortable elsewhere. Mighty Victor preferred the cool tiled bathroom floor over the warm carpeted bedroom floor, which also made the bathroom a more appealing place to spend time—and drink water.

Make Your Dog’s Water More Appealing

Dogs often prefer fresh, cool water over stale water in a bowl. To encourage your dog to drink from their own bowl, make it more attractive. Wash the bowl daily with soap and hot water to remove bacteria and drool buildup. Refill it with cool, fresh water several times a day.

Some dogs are picky about water quality. For example, one dog refused to drink from a public bowl if another dog had touched it, while another preferred “filthiest water.” This shows that water preference varies. Try offering water in a clean, separate bowl that’s always fresh and cool—ideally placed in a quiet, cool area.

Use Management to Prevent Access

If your dog keeps getting to the toilet, use management tools to block access. Simple solutions like lidded garbage cans or baby-proof latches can be adapted to secure the toilet. You can also close bathroom doors or use barriers like boxes or upside-down chairs to prevent entry.

Avoid locking the toilet lid with glue or keys, as this can backfire—like in the case of Mike, who locked his dog’s toilet with a key but forgot it during an emergency. Instead, focus on making the toilet less tempting and the dog’s water source more rewarding.

Train and Reward Alternative Behaviors

Once you’ve managed the environment, train your dog to use their own water bowl. Reward them with praise or treats when they drink from it. Use commands like “Leave It!” or “Off!” to redirect attention from the toilet.

Consistency is key. Over time, your dog will learn that drinking from their own bowl is more rewarding than sneaking a drink from the toilet.
