Why does my dog poop on concrete instead of grass?

It can be quite perplexing when your dog chooses to poop on concrete instead of the grass. However, there are a few reasons why this behavior may occur. Understanding these reasons can help you address the issue effectively.

Different surfaces offer different experiences

One of the key reasons why dogs prefer to poop on concrete is the texture of the surface. Grass and concrete offer vastly different experiences for a dog.


  • Soft and comfortable surface for sensitive paws
  • Natural scent markers from previous dogs
  • The ability to dig and cover waste


  • Firm and stable surface
  • No need to worry about leaves, rocks, or other objects
  • No need to dig as waste does not need to be covered

Based on these differences, some dogs may prefer the simplicity and cleanliness of the concrete surface.

Preference for familiar scents

Dogs have a highly developed sense of smell, and they rely on scent markers to understand their surroundings. The grass holds a wide variety of smells from other animals, which may include unfamiliar or potentially threatening scents.

Concrete, on the other hand, may offer a more neutral scent environment. Dogs may feel more comfortable eliminating on concrete because it does not carry foreign smells that could make them feel vulnerable.

Desire for cleanliness

Many dogs have an innate instinct to keep their living space clean. While grass provides a natural environment for dogs to relieve themselves, some dogs may prefer the cleanliness and ease of maintaining their territory when using a concrete surface.

Furthermore, certain dogs may find it more difficult to locate and remove their waste on grass due to its uneven surface. Concrete provides a flat and easily accessible surface, making the removal of waste simpler for them.

Medical or physical conditions

In some cases, dogs may choose concrete over grass due to underlying medical or physical conditions. Dogs with joint pain, arthritis, or other orthopedic issues may find it uncomfortable or difficult to squat on grass.

Some dogs with gastrointestinal disorders or sensitivity to certain foods may have an increased urgency to defecate, leading them to choose the nearest available surface, which may be concrete.

Improper potty training or environmental factors

In a few instances, the preference for concrete may be a result of inadequate potty training. If a dog is not properly trained to eliminate outdoors on grass from an early age, they may develop a preference for concrete. Additionally, certain environmental factors such as limited access to grassy areas or the presence of specific smells or noises in grassy locations may deter a dog from pooping on grass.


In conclusion, there can be multiple reasons why your dog prefers to poop on concrete instead of grass. It could be their preference for a different texture, the desire for a cleaner environment, a need for familiar scents, underlying medical conditions, improper potty training, or specific environmental factors. Identifying the underlying cause and addressing it through proper training, environmental adjustments, or seeking veterinary advice if necessary can help encourage your dog to eliminate in more appropriate areas.
