Stepping in dog poop is embarrassing, though a simple rinse and a good laugh at oneself are sufficient remedies for the incident. However, slipping on it and hurting yourself is no laughing matter.
In fact, if you were on somebody else’s commercial property, slipped on animal pee or poop, and consequently suffered a painful sprain, bone fracture, or head injury, you have every right to sue the owner of the property, given that the latter:
Caused the surface to become slippery (i.e., the owner did not clean up after their pet);
Knew the floor was.
