Why Dogs Poop in Crates & How to Stop It

Why Dogs Poop in Their Crates

Dogs naturally want to keep their den—like a crate—clean. This instinct is strong in most dogs, but certain situations can override it. A crate that’s too large may encourage a dog to use one corner as a bathroom while sleeping elsewhere. Conversely, a crate that’s too small can force the dog to lie in its own mess, which damages the natural instinct to avoid soiling the sleeping area.

Some dogs, especially those from puppy mills, may have lived in filthy conditions where they were forced to sleep in waste. This can lead to a long-term habit of not caring about cleanliness. In these cases, the dog may not understand the concept of keeping a clean sleeping space, even if the crate is now clean.

Crate Size Matters

The crate should be just big enough for the dog to stand up, turn around, and lie down comfortably. If it’s too large, the dog may eliminate in one corner and sleep in another. If it’s too small, the dog may be forced to lie in an accident, which can discourage the natural desire to stay clean.

Experts recommend checking the crate size and adjusting it as the dog grows. A properly sized crate helps the dog associate the space with cleanliness and rest, not elimination.

Timing and Routine Are Key

Puppies have little bladder control—especially at 8 weeks old. They need to go out immediately when they feel the urge. Keeping a puppy in a crate for too long without breaks increases the chance of accidents.

To prevent this, take the dog out frequently—after meals, drinks, naps, and play sessions. Use crate time to stretch out bathroom breaks, not to extend them. Short, consistent crate sessions help build bladder control over time.

Clean Up Immediately and Correctly

If an accident happens, clean it up right away. Use an enzymatic cleaner to remove all odor traces, especially on crate pads or floors. If using towels, replace them immediately after an accident and clean the crate surface.

Any lingering smell can signal to the dog that the area is acceptable for elimination. A clean crate experience helps retrain the dog’s instinct to keep the space clean.

Rebuild the Clean Crate Habit

For dogs with chronic crate soiling, start by ensuring the crate is the right size and always clean. Use consistent routines and positive reinforcement when the dog goes outside.

Some trainers recommend creating a “doggy RV” approach—making the crate a clean, safe, and rewarding space. This helps reestablish the dog’s natural den instinct. Patience and consistency are essential, especially for dogs with past trauma or poor training.
