Why do people own rat dogs?

Out of all the adorable fun loving dopey dogs you could pick, why, why, why, why would you pick a rat dog? Can anyone offer some insight? Psychology behind this unsolvable problem? I can’t understand it. They’re clingy. They yap. They can’t go out in the cold without wearing a sweater, AND WHEN THEY DO, THEY SHAKE VIOLENTLY. At least the ones I’ve had experience with, anyhow. They are annoying in general. You can’t cuddle or play with them, or you risk smashing/killing them. They don’t play fetch, they are dumb in general, and they aren’t cute. In addition they obviously don’t protect you or your house while you’re away, instead they sit in a corner and lick the wall and, again, spend the day shaking violently and puking on the couch because they miss their owner.

PS I love dogs. All dogs. Except these.

Anyone?
