9Munchkin the Mystery Mutt
Munchkin is perhaps one of the most decorated ugly dogs in recent history, having won several competitions for Ugly Dogs/Mutts and been featured on television and print media outlets all over the world.
Her breed is completely indeterminable; her vet calls her a "Canardly," as in "Can hardly tell [what she is]." Munchkin snorts when she walks (waddles?) and has wiry gray hair around her neck that sticks out on its own without the use of any combing or hair products. [Source]
