I have a run off a dog door with chain link fencing. It is currently 5 X10 and will soon be expanded to 10 X 10. It has gravel and some mulch for “footing” with some patio blocks along the edging.
What would anyone recommend as footing when I expand? It is for two small dogs that do not dig much. Would like it to be fairly easy to clean, not too hot in summer, and not too expensive.
