Amenities are a great way for condos to differentiate themselves, and one way to do that is by appealing to dog owners. And one way to appeal to them is to have a dog run.
What's a dog run? It's a place where your dog . . . can run.
These are typically located in private spaces, often on rooftops or terraces, for convenient use exclusively by the energetic pooches of residents.
It's pretty awesome to be able to take an elevator to a terrace with a skyline view so your dog can get in some laps while you get some fresh air.
