I understand your opinion. I'm kind of cleanliness obsessive and I'm always said I think and do too much about cleanliness. However, my SO is not. He saw the dog urinated near BBQ grills in the courtyard. Even though he didn't care about cleanliness so much, he thought it was not good. Then he saw the dog pooped near the swimming pool entrance, he thought that was enough for him. He said it was like seeing people letting small kids excrete in the public places for him.
We understand animals in the nature come and excrete in our courtyard. However, we are assuming the dog owners can control their dogs in some level to excrete where they do. If they can, we would appreciate it if the fellow tenant takes her dog somewhere to excrete besides the courtyard where we cook and eat. It's a personal preference. I do understand some people agree with it and some don't.
