Yup, I have one because I have a small dog with a tiny bladder who likes to pee in the middle of the night. I didn't worry, until the morning DH got up really early for work while it was still dark out and saw a coyote standing on the street in front of my house!
So, we rigged up a 6x12 chain link dog kennel with a roof and a locking gate on the concrete slab against our garage, attached it to the wall, added some mulch and a "tree" (a big old stick screwed to a base) and our dog door opens up into it.
Its works great, and I can let them have access to a potty spot even when I am not home and no stray cats or raccoons can get in and the dogs are safe from scary predators.
