Above is a Japanese woodblock print from 1886. It depicts a half tiger half tengu beast defeating cholera by clobbering sick people with it's massive testicles... Yeah.
EDIT: There's some controversy as to whether it actually is half tengu (see comments). I know that tengu usually look like birds not dogs. It's possible that it's called a tengu because it's being mistaken for the Chinese tiangou, or maybe they're literally just calling it a heavenly dog. If any of you are experts in art history and/or Japanese mythology let me know.
