Porch Potty is the #1 outdoor or indoor potty for dogs; great for patios, small yards, condos, balconys or apartments.  Eliminate the need to take your dog for a walk in poor weather in addition to the yellow dead areas in your lawn with this unique and easy to clean porch potty.  Check it out on the internet under "Porch Potty".  One of the recommendations reads:  "It really does put a nice grassy yard right outside your porch or patio door. I used the Training Sod for the first few weeks for the smell of fresh, real grass, then switched to the Synthetic Grass for a care free lawn for both my dog and myself. The Porch Potty truly does what it says and I highly recommend it for anyone!"  We bought this one because our aged female dog was killing our new grass but apparently you cannot teach old dogs new tricks so instead we replaced the entire yard with synthetic grass.  Now we have an unused porch potty for sale to some lucky customer out there.  Respond to "ladyblues@comcast.net" and come take a look.  Cost new is $259.00 plus shipping and handling.  Sale now for $100 or BO.
