New item in development: I assume you've seen the commercial for "Doggy Steps," an item that allows your wuss-dog to climb onto your bed or couch. I'm developing what is essentially a wheelchair ramp for dogs who have lost the use of their hind legs. It's the next logical step. I will call it "The Rise Over Dog-Run."
You can already purchase it at any nearby hardware store. It's a piece of wood. But the secret formula for the length is the square root of the distance from your couch to your coffee table squared added to the height of your couch squared. This idea has been in the works since the time of the Pythagoreans.
