Definitely laziness.

My old townhouse was a middle unit of three. Myself and the lady to the left of me would just shovel out a section of the yard next to the patio for the dogs to go. The third tenant on the other side of me wouldn't clean up for MONTHS. The smell got so bad during the spring/summer thaw that I could smell it from the either of the two second floor bedrooms that were opposite the back yard.

I eventually had to knock on their door and tell them to get their "sh*t" straight and clean up their dog's mess.
