Do the dogs go potty on the triangular grass area? I would like to limit, as much as I can, where Binx goes potty. I figure it will be easier to clean up, and still keep some of the postage stamp sized lawn intact. I wondered about river rock, too...it would be small...but, I wonder if he wouldn't like the feel of it under his freezer sized paws.

I just think the brick work looks sharp. Did you mom do it herself? Just use a hand shovel to dig? Did she dig it all out a few inches deep, lay the brick, then roll the dirt over it again??
