Chinese Crested and Chihuahua mix Elwood was the winner of the World's Ugliest Dog contest in 2007, and had placed second in 2006. His owner Karen Quigley of Sewell, New Jersey, says, "I think he's the cutest thing that ever lived."
The breeder was going to euthanize him as a pup, "because he was too ugly to sell," but Karen rescued him. So what might've been a short life became a good life with regality and awards.
Elwood's tongue was literally too big to stay in his mouth. Add to that a jaw with too few teeth and the "lolling to one side" effect was quite exaggerated.
He often had a drippy snotty nose to go with his shiveriness. Shaking is common among chihuahuas and is a neurological trait rather than caused by being cold. It's caused by emotional states more than temperature, so can indicate they're happy, worried, or filled with expectation. In skittish or poorly bred chihuahuas it can be endless vibrating.
Personally I find Elwood's looks rather pleasant. I mean compared to some of the annual winners with warts and discolorations that make them seem plague-ridden. Elwood also had a good personality so he won over people with ease.
