How to Stop Your Dog from Drinking from the Toilet

Why Dogs Drink from Toilets

Dogs are naturally drawn to toilet water because it’s often cooler and fresher than the water in their bowl. According to research, dogs prefer fresh, cool water over warm, stale water that’s been sitting for hours. Toilet water is typically refreshed more often, making it taste better to dogs—even if it contains cleaning residue or bacteria.

Some dogs, like Jerome in one example, even prefer “filthiest” water and remain healthy, while others, like Maya, avoid water that’s been touched by other dogs. This shows that dogs have individual water preferences, and their behavior often reflects what they find most appealing.

Make Your Dog’s Water More Appealing

The best way to stop your dog from drinking from the toilet is to make their own water bowl more attractive. This means offering fresh, cool water that’s clean and inviting.

Wash your dog’s water bowl every day with soap and hot water. Even if you refill it with clean water, the bowl can quickly become dirty from drool and bacteria buildup—especially since dogs drink by lapping water with their tongues, which creates splashes and slobber. This mess makes the water unappealing and unsafe over time.

Refill the bowl several times a day, especially in warm weather. A cool, clean bowl is more tempting than a stale one—and far safer than toilet water.

Use Environmental Management

Instead of trying to lock the toilet or block access, focus on managing the environment to prevent the behavior.

Keep the dog’s water bowl in a quiet, low-traffic area where it’s not disturbed. Use a bowl that’s easy to clean and doesn’t retain odors. Some dogs avoid public or shared bowls, so having a dedicated, personal water source is key.

If your dog is drawn to the bathroom, consider closing the door when you’re not around. But don’t rely on locks—dogs like Mazel can open doors with their nose, and locking the toilet can lead to accidents, as one owner discovered when he forgot the key.

Train Your Dog to Choose the Right Water Source

While management is crucial, you can also train your dog to prefer their own water bowl.

Use positive reinforcement: reward your dog with praise or a treat when they drink from their bowl. Over time, they’ll learn that the bowl is the best source of water.

Avoid using punishment. Instead, redirect their attention with a command like “Leave it!” or “Off!” when they approach the toilet. Pair this with a reward when they go to their bowl instead.

Remember: It’s About Preference, Not Misbehavior

Dogs aren’t trying to be naughty—they’re responding to what tastes best and feels most refreshing. If your dog drinks from the toilet, it’s usually because their water bowl isn’t meeting their needs.

By offering clean, cool, fresh water in a clean bowl, you’re not just stopping a bad habit—you’re improving your dog’s overall well-being. A satisfied dog is a healthy, happy dog.
