> But how certain are you that the dog didn't actually poop on the property or entered indoors?

If the renter had video cameras in the house, and the only image he could find of the dog was sitting on the porch, it probably wasn't because the owner didn't bother looking.

The author didn't have a dog. Someone brought a dog, and they stayed on the porch. The owner believes they caught the renter in a gotcha, but they didn't.
