With the number of dogs we've got (7 total, 3 fosters) I don't think it would be practical for us. I've considered one before, because I hate the potty pad flooring look
If you do get one Mercury, do let us know how it goes. I'm interested in just how long that patch of sod will actually last.....with 7 dogs, I would give it a day or so
I love the fire hydrant, it's too cute!
