I'd like to section off a 10x6 area of my yard for my new puppy to do her business and I'm wondering what material to use, she already uses this area now and it's a nice little distance away from the house and the rest of the yard.
My landscaper suggested 3/4" River Stone and said he's built them for other clients.
My neighbor has a "mulch pit" and he said his dogs loved it and he would just go out there and turn it over with a shovel once a week.
It seems like the mulch would get messy in the rain? Has anyone else built one of these? What materials would you recommend?
