Unfortunately the yard itself is not huge, bigger then they had, but not as big as I would like. We have some changes to make. There is a covered pario deck, an above ground jacuzzi too in the back yard, BUT there are 2 huge covered patios and there is space all around the house they can run from one side to the other it's open from the front of the house to the side to the back to the other side. So they have room to run, but it's mostly concrete right now. We plan to add more grass in time. But I'm thinking of doing a fake grass system. They kill my grass every time. Their pee turns the grass yellow even if we water it every day. ARG!
