I would argue that buildings that allow dogs benefit as far as higher prices -- after all, if you lose the dog-owner as a potential buyer, your "demand" decreases.
This ignores the obvious fact that some buyers value a dog-free building.
Washington Plaza was a dog free rental building. Now it is a dog friendly co-op building. We love the barking and the urine.
The city recently cut down a young dead tree in the sidewalk. It was there for a couple of years. The dogs had been urinating on it. The other tree next to it is half dead.
Maybe they could make the pool into a dog friendly urinal.
