<p>How old is the dog? If it is an older dog that has been very well trained, I wonder if this is a good idea. A couple of our adult dogs always acted embarrassed and shamed if they went any where but in the yard. We did have a handicapped dog that was accident prone and she didn’t mind if she had an accident.</p>

<p>How about a small barrel planter filled with dirt and some grass on top? Plant with sod and rotate dirt and sod as necessary.</p>
