If I would have had this dog pet chime when I was little, there never would have been any puddle accidents in the house. This cool chimer goes on the floor by the door, and when Fido (or Chip or Snickers) needs to go outside to pee, we just step on the pad and it alerts our humans that we need to go out. Why didn't we think of this and put it up on ebay for sale? It's because Linda was too busy cleaning the carpet from my accidents, thats why.
